NOTE
The usage precautions are as follows:

l
A device can store keys in plaintext, reversible algorithm encryption, or irreversible algorithm
encryption mode. The plaintext mode has the low security level, and the irreversible algorithm
encryption mode has the highest security level. Use different storage modes for different scenarios.
Exercise caution when using an insecure storage mode. The system automatically selects the
irreversible algorithm encryption mode to store local user keys. Generally, the reversible algorithm
encryption mode is used to store protocol keys to meet interworking requirements.
If the plaintext mode is used, a password is stored in plaintext in the configuration file. This results
in high security risks. The plaintext mode applies only to scenarios with special requirements, such
as compatibility and interworking requirements.
Using a password or a key without a change leaves the password prone to being stolen or cracked,
which is more likely in a longer duration. Changing the password on a regular basis may avoid such
incidences, and therefore is recommended.

Logging In to the ATN
About This Chapter
This chapter describes how to log in to the ATN for later commissioning. Three login methods,
login by using the console interface, Telnet, and SSH, are introduced.
NOTE
Command levels are associated with user privilege levels. A user can run only the commands at the same
or lower level than the user privilege level. This mechanism ensures device security.
For more information about user privilege level configurations, see ATN Multi-service Access
Equipment Configuration Guide - Basic Configurations - Configuring User Login..
l When you log in using the SSH (STelnet) method for the first time, the default user name is root, and
the default password is Changeme_123. To improve service security, change the user name and
password immediately after configuring services.
l When you log in through a console interface for the first time, no default user name or password is
available. Therefore, configure a user name and password after the login.
l The console interface login method is still available if you log in not through a console interface.
Therefore, to prevent unauthorized users from logging in through the console interface, configure a
user name and password for the console interface login method immediately after you log in using
another method and configure services. This configuration prevents unauthorized users from querying
or modifying service configurations.
l After the ATN device is powered on, it will automatically bind the management network interface to
the VPN for exclusive use (__LOCAL_OAM_VPN__) and configure the IP address 129.0.0.1/24 for
the management network interface.
Use the IP address 129.0.0.1 to stelnet to the ATN that is powered on for the first time.
The user can configure any other IP address for the network segment 129.0.0.0/24 on the PC, and
directly log in to the ATN device using the user name and password for on-site equipment maintenance.
The IP address of the management network interface can be changed or deleted. The management
interface can be disabled as required.
2.1 Logging In to the ATN by Using SSH
This section describes how to log in to the ATN by using SSH. SSH is a secure remote login
protocol developed based on the traditional Telnet protocol. Compared with Telnet, SSH is
greatly improved in terms of the authentication mode and data transmission security.

This section describes how to log in to the ATN by using Telnet. A Telnet operation allows you
to log in to a remote device for device management.
2.3 Logging In to the ATN by Using the Console Interface
This section describes how to use the HyperTerminal in Windows on the PC to log in to the
ATN after setting up a local configuration environment with the console interface.
2.4 Clearing the Password
This section describes how to clear the password by setting DIP switches when a user cannot
log in a device due to an invalid login password.

The ATN is running properly.The status indicators are green.
The ATN has been logged in using the console interface and an IP address for each interface
has been configured on the ATN.
A direct or reachable route exists between the SSH client and the ATN.
Perform the following configurations on the ATN that serves as the SSH server:
Procedure
Step 1 Configure a VTY user interface to support SSH.
1.
Run the system-view command to enter the system view.
2.
Run the user-interface [ ui-type ] first-ui-number [ last-ui-number ] command to enter the
user interface view.
3.
Run the authentication-mode aaa command to specify AAA authentication as the
authentication mode.
4.
Run the protocol inbound ssh command to configure SSH as the access protocol in the
VTY user interface view.
NOTE
AAA authentication must be configured in the VTY user interface view; otherwise, the protocol
inbound ssh command does not take effect.
Step 2 Run the ssh user user-name command in the system view to create an SSH user.
Step 3 Create an RSA or DSA key pair.
l Run the rsa local-key-pair create command to create a local RSA key pair.

NOTE
l Configure the rsa local-key-pair create command to generate a local key pair before completing
other SSH configurations. The minimum length of the server key pair and the host key pair is 512
bits, and the maximum length is 2048 bits.
l After a local key pair is generated, you can run the display rsa local-key-pair public command
to view the public key in the local key pair.
l To clear the local RSA key pair, run the rsa local-key-pair destroy command to destroy all local
RSA key-pairs, including the local key-pair and server key-pair.
Check whether all local RSA key pairs are destroyed after running the rsa local-key-pair
destroy command. The rsa local-key-pair destroy command configuration takes effect only once
and therefore will not be saved in the configuration file.
l Run the dsa local-key-pair create command to generate the RSA local-key-pair.
NOTE
l You must configure the dsa local-key-pair create command to generate a local key pair before
completing other SSH configurations. The length of the server key pair and the host key pair can
be 512 bits, 1024 bits and 2048 bits. By default, the length of the key pair is bits.
l After a local key pair is generated, you can run the display dsa local-key-pair public command
to view the public key in the local key pair.
l To clear the local DSA key pair, run the dsa local-key-pair destroy command to destroy all local
DSA key-pairs, including the local key-pair and server key-pair.
Check whether all local DSA key pairs are destroyed after running the dsa local-key-pair
destroy command. The dsa local-key-pair destroy command configuration takes effect only once
and therefore will not be saved in the configuration file.
Step 4 Perform the operations as described in Table 2-1 based on the configured SSH user
authentication mode.

to configure RSA authentication.
-
2. Run the rsa peer-public-key keyname [ encoding-type { der |
openssh | pem } ] command to
configure an encoding format for an
RSA public key and enter the RSA
public key view.
Huawei data communications
devices support only the DER
format for RSA keys before VRP
V500R012C01 version. If you use
an RSA key in non-DER format,
use a third-party tool to convert
the key into a key in DER format.
The default encoding format is
distinguished encoding rules (DER)
for an RSA public key.
In addition to DER, RSA keys
need to support the privacyenhanced mail (PEM) and
OpenSSH formats since VRP
V500R012C01 to improve RSA
usability.
Third-party software, such as
SecureCRT, PuTTY, OpenSSH,
and OpenSSL, can be used to
generate RSA keys in different
formats. The details are as
follows:
l The SecureCRT and PuTTY
generate RSA keys in PEM
format.
l The OpenSSH generates RSA
keys in OpenSSH format.
l The OpenSSL generates RSA
keys in DER format.
3. Run the public-key-code begin
command to enter the public key
edit view.
4. Enter hex-data to edit the public

Troubleshooting
If the SSH login fails, perform the following operations:
1.
Check that network connections are proper.
Check whether unstable connections that cause packet loss or occasional login failures exist
in the network. If network connections are improper, follow the procedure described in
"The Ping Operation Fails" in the ATN Multi-service Access Equipment Troubleshooting
to locate and rectify the fault and ensure a stable connection between the SSH client and
the SSH server.
2.
Check that SSH services are enabled.
Run the display ssh server status command to view configurations on the SSH server.

command line prompt such as <HUAWEI> is displayed. It indicates that you have entered
the user view.
Troubleshooting
If the Telnet login fails, perform the following operations:
1.
Check that network connections are proper.
Run the ping command on the client to check network connections. If ping results are
negative, network connections are faulty and Telnet connections cannot be set up.
Check whether unstable connections that cause packet loss or occasional login failures exist
in the network. If network connections are faulty, follow the procedure described in "The
Ping Operation Fails" in the ATN Multi-service Access Equipment Troubleshooting to
locate and rectify the fault and ensure that the Telnet client can successfully ping the Telnet
server.
2.
Check whether login users on the ATN have reached the maximum.

If an ACL is configured but the IP address of a client from which the access is permitted
is not specified in ACL rules, the client cannot telnet to the ATN. This means that to allow
a client to telnet to the ATN, you must specify the IP address of the client in the permit rule
of the ACL bound to VTY user interfaces.
4.
Check that the access protocol has been correctly configured in the VTY user interface
view.

protocol inbound ssh
The protocol inbound { all | ssh | telnet } command is used to specify protocols supported
by the current user interface. telnet is the default parameter. If ssh is specified, Telnet login
is prohibited. If all is specified, both Telnet login and SSH login are allowed.
5.
Check whether extended VTY user interfaces 16 to 20 are available to login users.
These user interfaces are reserved for NMS users. Whether VTY user interfaces 0 to 14 are
all used, VTY user interfaces 16 to 20 are open to NMS users (whose user type is netmanager) only, not common login users.
The display users command can be used to check the user login information of every VTY
user interface.
6.
Check that a password has been set in the user interface view.
If the authentication-mode password command has been run in the VTY user interface
view to set the authentication mode to password, the set authentication password
command must be run to set an authentication password.
The authentication mode can also be set to aaa by running the authentication-mode aaa
command.
7.
Check that the user level is correct.
If the authentication mode in the VTY user interface view is set to password or none, you
need to check the user level. Low-level users, after login, are not allowed to run high-level
commands such as the system-view command.
If you use an administrator account to log in to the ATN, you can run the user privilege
level level command to configure the level of commands that the user logging in through
the current user interface can use.

If the login fails, click Disconnect and then Call. If the login still fails, repeat Step 1 to check
whether the parameters or physical connections are correct. If they are correct, log in to the
ATN again.
2.4 Clearing the Password
This section describes how to clear the password by setting DIP switches when a user cannot
log in a device due to an invalid login password.
Prerequisites
The device has been normally powered on.
Context
This operation is performed when an attempt to log in to a device fails because the user forgets
the password.
ATN 910/ATN 950B support this operation.
Procedure
Step 1 Remove the system control board.
NOTE
For a device equipped with active and standby control boards, remove both boards and then perform related
operations on them.
Step 2 Set DIP switches 1 to 4 on the system control board to 1, 1, 0, and 1 respectively.
The number 1 indicates that the DIP switch is set to the side with numbers while the number 0
indicates that the DIP switch is set to the side with letters.
Step 3 Install the removed system control board back.
When the device starts, it identifies the status of DIP switches and clears the configuration files
loaded onto it. In this way, the password is also cleared.
Step 4 Five minutes later, the configuration files are cleared, then remove the system control
board.
Step 5 Set DIP switches 1 to 4 to 0 each.
NOTE
This operation prevents the configurations files from being cleared each time the device restarts.
Step 6 Install the removed system control board back.
Default settings of the device are restored.

Troubleshooting
If the physical status is Down, perform the following operations:
1.
Run the display this command on both the local and remote interfaces to check whether
they have been shut down. If either one of them or both of them have been shut down, run
the undo shutdown command in the interface view. After that, run the display this
interface command to check whether the interfaces have gone Up.
2.
At this step, optical interfaces and electrical interfaces are handled differently.
l If optical interfaces are used for connection, skip this step.
– Check that the fiber is properly installed. If the fiber is improperly installed, reinstall
the fiber. After that, run the display this interface command to check whether the
interface status is Up. If the fiber is properly installed but the interface status is Down,
perform the next step.
– Check that the optical modules on the interfaces of the local match that of peer
devices, including interface types, wavelengths, and optical powers of optical
modules. If they are not matched, replace optical modules. Then, run the display
this interface command to check whether the interface status is Up.
l If electrical interfaces are used for connection, check that the network cable is properly
installed. If the network cable is improperly installed, reinstall the network cable. After
that, run the display this interface command to check whether the interface status is
Up. If the network cable is properly installed but the interface status is Down, perform
the next step.
3.
If optical interfaces are used for connection, use a fiber or optical modules. If electrical
interfaces are used for connection, use a network cable or electrical modules. After that,
run the display this interface command to check whether the interface status is Up.
4.
Run the display trapbuffer command to check whether interface-related alarms have been
generated. If such alarms have been generated, consult the Alarm Reference of the ATN.
5.
If the physical status is still down, collect the following information and contact Huawei
technical support personnel:
l Results of the preceding operation procedure
l Configuration files, log files, and alarm files of the ATN

– Check that the interface configurations such as the MTU, TTL of packets, format
of transmitted Ethernet frames, and maximum QoS bandwidth on the local and
peer ends are consistent. If they are inconsistent, adjust them to ensure consistency.
– Check that the traffic is normal.
3.
Check that the fiber is properly and correctly installed. This means that the fiber is
connected to the correct transmit optical module and receive optical module.
4.
Perform self-loop detection on interfaces to check whether the interfaces are normal.
After you run the undo shutdown command in the interface view, connect the RX
end and TX end of an optical module on the local interface using a fiber. Check
whether the interface is Up. If the interface is Up, the local interface is normal. Perform
the same operation on the remote interface. If the remote physical layer is Up, the
remote interface is normal. You need to replace the fiber.
5.
l
If the fault persists after the preceding operations are complete, contact Huawei
technical support personnel.
If an Ethernet interface cannot be pinged, perform the following operations:
1.
Check that the local end is correctly connected to the peer end. Observe the Link
indicator on the NPU where the local Ethernet interface resides. If the indicator is on,
the link works properly. If the indicator is off, check the optical module, interface,
fiber, and the device.
2.
Check that the auto-negotiation modes on the local and peer Ethernet interfaces are
consistent.
3.
Check that the IP address of the local Ethernet interface belongs to the same subnet
as that of the peer Ethernet interface. This means that the two IP addresses must have
the same network address and different host addresses. If the two IP addresses do not
belong to the same subnet, reconfigure the IP addressesand the masks.
4.
If the fault persists after the preceding operations are complete, contact Huawei
technical support personnel.

Check that the physical layer is Up.
a.
Run the display controller e1 command to view interface information on each end.
If the physical status is displayed as Administratively Down, the shutdown
command has been run on the interface. Run the undo shutdown command to enable
the interface.
If the physical status is displayed as Down, check the following items:
l Fiber is properly connected to the local interface and the indicator for the interface
is in a normal state.
l Fiber is properly connected to the peer interface. Run the display this interface
command in the interface view to check if the physical status of the peer interface
is Administratively Down and if loopback is configured on the peer interface.
l Interface configurations, such as the operation mode and line coding/decoding
format, on the two ends are consistent, and the clock modes configured on the two
ends are correct.
b.
If the fault persists, run the loopback command in the CE1 interface view.
If the physical status of the interface is Up, the hardware on the local end works
properly. The problem lies in the cable, and you need to replace the cable. If the
physical status of the interface is Down, the board where the interface resides is faulty.
The board needs to be repaired.
2.
Check that the link layer is Up.
If the link status is Down, run the display interface serial command on each end to check
the link status.
3.
a.
Check whether the two ends use the same link layer protocol. The link layer can go
Up only when the two ends of the link use the same link layer protocol.
b.
If the physical layer is Up, check whether correct IP addresses are configured for the
interfaces on the two ends.
c.
If the LCP negotiation status is not opened, LCP negotiation has not been completed
yet. LCP negotiation is completed only when the LCP negotiation status is opened.
d.
If the LCP negotiation status is opened and the IPCP negotiation status is not opened,
IPCP negotiation has not been completed. IPCP negotiation is completed only when
the IPCP negotiation status is opened.
If the interfaces on the two ends of the link still cannot ping each other even if all
configurations are correct, run the display interface serial command to view statistics on
the interfaces and contact Huawei technical support personnel.
4.3 Checking the Optical Power of Interfaces
This section describes how to verify whether the optical power of SFP optical modules meets
requirements.
You need to check whether the optical power of SFP optical modules meets requirements. If the
output optical power of SFP optical modules does not meet requirements, packets will be lost
and communication will be interrupted on the network layer.

on the two ends against the "List of LPU Interface Attributes" to determine if the input optical
power is within the allowed range.
NOTE
See "List of LPU Interface Attributes" in the appendix. To use the optical module on the local end, the following
two conditions for the input optical power of the optical module must be met:
l The input optical power must be greater than the receiver sensitivity of the optical module (3dBm).
Otherwise, the peer end will not receive any signals.
l The input optical power must be lower than the overload optical power (3dBm). Otherwise, the optical
module may be damaged.

Alarm: none
As shown in the command output, the CT1 interface should be up and there should be no alarms
or errors on the link.
----End
Handling Common Faults
After the T1 interface is configured, the interface state is down or alarms are reported for the
interface. The following describes the fault handling procedure for each possible cause.
1.
Cause 1: The T1 interface is shut down.
Handling procedure:
a.
Run the display this interface command to view the basic configurations of the T1
interface.
[HUAWEI-T1 0/3/0]display this interface
T1 0/3/0 current state : Administratively DOWN
Description : HUAWEI, T1 0/3/0 Interface
Physical layer is Packet Over ESF
clock master, linecode b8zs, loopback none
lbo none, cablelength short 0-133 feet
Alarm: LAIS
If the interface is shut down, "Administratively DOWN" is displayed in the first row
of the command output. In this situation, run the undo shutdown command to the
interface to turn on the interface. After that run the previous command to check the
interface configurations again. If the interface has been shut down, the interface state
should change to up after you run the undo shutdown command. If the interface state
remains down, see the fault handling procedure for cause 2 or 3.
2.
Cause 2: Alarms have been reported for the interface.
Handling procedure:
a.
In the T1 interface view, run the display this interface command to view the alarm
information.
[HUAWEI-T1 0/3/0]display this interface
T1 0/3/0 current state : DOWN
Description : HUAWEI, T1 0/3/0 Interface

Alarm: LOF
Issue 02 (2014-04-30)
b.
If a LOF alarm is displayed in the command output, the channelized mode or frame
format for the T1 interface is inconsistent with that of the connected interface. Correct
the settings make the channelized modes or frame formats consistent for the two
interfaces.
c.
If a LOS alarm is displayed in the display this interface command output, check
whether the specified lbo and cablelength values are consistent with the actual

physical cable type and length. If not, correct the settings to make them consistent. If
the LOS alarm persists after you correct the settings, the physical line is faulty. See
the fault handling procedure forfor cause 3.
d.
If an LAIS or LRDI alarm is reported for the interface and the alarm has been
configured as a condition for the interface to become down, handle the alarm by
referring to the procedures for handling link layer protocol faults. Then determine
whether to disable the alarm from being a condition for the interface to enter the down
state depending on the actual situation.

3.
Cause 3: The T1 interface is connected incorrectly, the T1 cable or the interface is damaged.
Handling procedure:
a.
In the T1 interface view, run the display this interface command to view the basic
configurations of the T1 interface.
[HUAWEI-T1 0/3/0]display this interface

clock master, linecode b8zs, loopback none
lbo none, cablelength short 0-133 feet
Alarm: LOS
If a LOS alarm has been reported for the interface, then no signal is sent to the interface.
b.
Perform a loopback on the T1 interface by running the loopback command to check
whether the T1 interface state will change to up.
NOTE
The interface loopback mode is associated with the interface clock mode. To be more specific, clock
master corresponds to loopback local and clock slave corresponds to loopback remote. Therefore,
when running the loopback command, ensure that the correct loopback mode is used for the
corresponding clock mode.
The following figure shows the loopback modes and the following table describes the
loopback modes.

Loopback
Mode
Description
loopback local
In the loopback local mode, a local signal is transmitted by the
Tx interface to the Rx interface to determine whether the local
T1 line is normal. If the physical state of the local T1 interface
changes to up after you run the loopback local command, then
the local T1 line is damaged or the T1 interface is damaged.
loopback remote
In the loopback remote mode, a signal received by the Rx
interface is directly sent to the Tx interface to determine
whether the T1 line from the remote T1 interface to the local
T1 interface is normal. If the physical state of the remote T1
interface changes to up after you run the loopback remote
command, then the T1 line from the remote T1 interface to the
local T1 interface is normal. Otherwise, the T1 line between
the two T1 interfaces is damaged or the connection between the
two T1 interfaces is incorrect.
Select the required loopback on the T1 interface. If the T1 interface becomes up after
the loopback is performed and the configurations for the local and remote T1 interfaces
are the same, the T1 cable between the two interfaces is connected incorrectly or the
T1 interface is in poor contact. Check whether the T1 cable is connected correctly. If
not, correct the connection. If so, the T1 cable is damaged, so replace the T1 cable. If
the connection is correct and the physical state of the T1 interface is still down after
the loopback is performed, some physical component on the T1 interface is damaged.
In this situation, contact Huawei technical support engineers.
4.5 Commissioning XDSL Interfaces
This section describes how to ensure XDSL interfaces function properly.
Prerequisites
Hardware commissioning has been completed and the ATN device to be commissioned is
running properly.
NOTE
Only the ATN 910 supports XDSL interface.
Context
As shown in Figure 4-3, a static routing protocol has to be deployed in the network to ensure

Handling Common Faults
An ATM interface is faulty.
1.
Cause 1: The AC-side interfaces that carry the ATM service are not up. These interfaces
include the E1, serial, and IMA interfaces.
Handling procedure:
2.
a.
In the system view, run the display interface brief command to check the status of
the ATN service interfaces. If the physical state and protocol state of the interfaces
are up, see the fault handling procedure for cause 2.
b.
If the sub-interfaces or the main interfaces are shut down (the physical state of these
interfaces are displayed as down), enter the interface view and run the undo
shutdown command to turn on the sub-interfaces or interfaces.
c.
If the physical state of the serial interface is down, then the E1 interface is not up.
Handle the E1 interface fault.
d.
If the physical state of the serial interface is up but the protocol state is down, in the
serial interface view run the display this command to check whether the protocol type
of the serial interface is ATM. If it is not ATM, change it to ATM. In the E1 interface
view, run the display this command to check whether the timeslot configurations
specified by the channel-set command for the E1 interface on the ATN device are
consistent with the timeslot configurations for the E1 interface on the CX600. If they
are inconsistent, correct the configurations.
e.
If the interface for which ATM services are created belongs to an IMA group and the
physical state or protocol state of the IMA group is down, see the procedure for
handling an IMA group being down.
Cause 2: The PW or tunnel carrying the ATM service is down.
Handling procedure:

3.
4 Commissioning the Link Layer
a.
In the system view, run the display mpls l2vc command to view the status of the PW
where the ATM service is interrupted. If the VC is up, see the fault handling procedure
for cause 3.
b.
If the VC is down, check whether the VC ID, VC type, and control word of the ATN
device are consistent with those of the CX600. If they are inconsistent, correct the
configurations. Note that the VC ID and control word can be manually specified but
the VC type is determined by the sub-interface type (P2P or P2MP) and the connection
type (PVC or PVP).
c.
If they are consistent but the VC is down, handle the fault by referring to the MPLS
fault handling procedure.
Cause 3: The MAP PVC or MAP PVP on the ATN device is inconsistent with that on the
CX600.
Handling procedure:
4.
a.
In the sub-interface view, run the display this command to retrieve the MPA PVC
value of the PVC or the MAP PVP value of the PVP and compare the value with that
of the CX600. If the values are the same, see the fault handling procedure for cause
4.
b.
If the values for the ATN device and CX600 are different, change the value of the
ATN device or CX600 to the required value.
c.
If they are the same but the VC is down, handle the fault by referring to the MPLS
fault handling procedure.
Cause 4: The board hardware is faulty, or the board fails to function properly because of
an excessively high ambient temperature.
Handling procedure:
a.
In the system view, run the display temperature command to check whether the board
temperature exceeds the upper threshold. If this is the case, replace the board.
b.
If the service is still interrupted, collect the diagnose log and other logs of the ATN
device and collect the fault data using the one-click fault data collection function. Send
the logs and fault data to Huawei for further fault diagnosis.
The IMA group is down.
1.
Cause 1: The IMA group has been shut down manually.
Handling procedure: In the IMA group view, run the display this command to view the
buildrun information. If shutdown is displayed in the buildrun, run the undo shutdown
command. Otherwise, see the fault handling procedure for cause 2.
2.
Cause 2: No active link is available.
Handling procedure:
Issue 02 (2014-04-30)
a.
In the system view, run the display interface brief command to check the IMA group
status. If the physical and protocol states of at least one link in the IMA group are up,
then there are active links. In this case, see the fault handling procedure for cause 3.
b.
If the physical state is displayed as *down for all the links in the IMA group, then the
serial interface has been shut down manually. Enter the serial interface view and run
the undo shutdown command.
c.
If the physical state is displayed as down for all the links in the IMA group, then the
E1 line is faulty. Handle the fault by referring to the E1 fault handling procedure.

4 Commissioning the Link Layer
If the physical state is up but the protocol state is down for all the links in the IMA
group, check whether the E1 line on the ATN device and CX600 is bound to an IMA
group. If you cannot check the configurations of the CX600, remove the links from
the IMA group on the ATN device and change the scrambling setting (scramble or
undo scramble) or the timeslot setting (1-31 or 1-15,17-31) for the IMA group. After
that, add the links to the IMA group again and check whether the protocol is up. If the
protocol on the ATN device cannot go up after the preceding operations, then the
configurations of the CX600 contain errors.
Cause 3: The number of active links is smaller than the number of activated links.
Handling procedure:
a.
In the IMA group view, run the display this interface command to view the IMA
group information. In the command output, if "IMA_GRP_NE_STATE" is displayed
as "insufficientLinks", change the min-active-links value of the IMA group to a
smaller value or bind the IMA group to other links.
b.
If the IMA group is still down, collect the diagnose log and other logs of the ATN
device and collect the fault data using the one-click fault data collection function. Send
the logs and fault data to Huawei for further fault diagnosis.
The ATM bundle interface is down.
1.
Cause 1: The bundle interface has no member interface.
Handling procedure: Run the display current-configuration command to check whether
a sub-interface is added to the bundle interface. If no sub-interface is present, add the subinterface to the bundle interface.
2.
Cause 2: All member interfaces in the bundle interface are down.
Handling procedure:
a.
Determine which sub-interfaces that the bundle interface must contain.
b.
Run the display interface brief command to check the status of the sub-interfaces. If
the sub-interfaces are all down, determine the causes and handle the fault accordingly.
4.7 Commissioning TDM Interfaces

a.
If the AC status is displayed as down in the command output, see the fault handling
procedure for cause 3. If the session state is displayed as down, handle the fault by
referring to the MPLS fault handling procedure.
b.
If the AC status and the session state are displayed as up but the VC is down, check
whether the VC ID, VC type, and control word of the ATN device are consistent with
those of the CX600.
c.
If they are inconsistent, make changes properly to make them consistent. If they are
consistent but the VC is down, handle the fault by referring to the tunnel fault handling

Handling procedure 2:
a.
Check whether the QoS is configured for the network interface. If QoS is configured,
handle the fault by referring to the QoS fault handling procedure.
b.
If the physical state of the TDM link is displayed as *down, then the serial interface
has been shut down manually. Enter the serial interface view and run the undo
shutdown command.
c.
If the physical state of the TDM link is displayed as down, then the E1 line is faulty.
Handle the fault by referring to the E1 fault handling procedure.
d.
If the physical state is up but the protocol state is down, check whether the E1 line on
the ATN device and CX600 is bound to an IMA group If you cannot check the
configurations of the CX600, remove the links from the IMA group on the ATN device
and change the scrambling setting (scramble or undo scramble) or the timeslot setting

(1-31 or 1-15,17-31) for the IMA group. After that, add the links to the IMA group
again and check whether the protocol is up. If the protocol on the ATN device cannot
go up after the preceding operations, then the configurations of the CX600 contain
errors.
The bandwidth allocated to the TDM service on the NNI side is insufficient, or the service
packets of a higher priority occupied the bandwidth allocated to the TDM service.
1.
Handling procedure:
a.
Check whether the QoS is configured for the network interface. If QoS is configured,
handle the fault by referring to the QoS fault handling procedure.
b.
Check whether the bandwidth on the NNI side is sufficient for transmitting the TDM
service. For example, if n timeslots have been configured for the TDM service,
calculate the bandwidth required by one TDM service using the following formula:
TDM service bandwidth = n x 8 x 8000/8 + Length of the Ethernet packet header.
4.8 Commissioning MP Interfaces
This section describes how to commission MP interfaces.
Prerequisites
Hardware commissioning has been completed, the ATN device to be commissioned is running
properly, and the E1 cables on the AC sides of the PPP link are correctly connected.
Context
As shown in Figure 4-6, a static routing protocol has to be deployed in the network to ensure
normal communication between the ATN device and the network segment 192.167.1.0 where
the CX600B is located.

Commissioning Guide
4 Commissioning the Link Layer
Procedure
Step 1 Create a PPP serial interface and specify the protocol type of the interface as PPP. If necessary,
specify a CRC mode for the PPP link. The following uses serial interface 0/2/0:1 and mp-group
0/2/1 to describe how to commission MP interfaces. The default CRC32 mode is used for the
interfaces.
Step 2 Create an MP interface and configure the interface attributes, such as the long and short serial
numbers and fragment size. In this example, the default values are used.
Step 3 Create an MP group and add the PPP link to the MP group.
For the detailed procedure, see the guides to configure PPP and MP interfaces for ATN devices.
Then run the display this interface command on the ATN device to view the configurations of
the serial interface.
[HUAWEI-Serial0/2/0:1] display this interface
#

#
return
Step 4 On the CX600, use the same way to configure the same number of timeslots for the E1 link and
add the timeslots to an MP group. In addition, advertise the IP address of the MP group to the
OSPF routing table. After that, the LCP state of the PPP link is opened and the MP state is open
as negotiated by the device. If MPLS is also configured, the MPLS state will be also opened.
When the MP interface is used as a network interface, the service is forwarded correctly and no
packet is lost.

b.
If the VC is down, check whether the VC ID, VC type, and control word of the ATN
device are consistent with those of the CX600. If they are inconsistent, correct the
configurations to make them consistent. Note that the VC ID and control word can be
manually specified but the VC type is determined by the sub-interface type (P2P or
P2MP) and the connection type (PVC or PVP).
c.
If they are the same but the VC is down, handle the fault by referring to the MPLS
fault handling procedure.
Cause 3: A loopback has been performed for the interface.
Handling procedure:
a.
In the interface view, run the display this interface command to check the physical
state of the serial interface.

b.
2.
Select the member links and activate them to make the protocol state of the links up.
By doing so, you can ensure that the number of links of which the protocol state is up
is larger than or equal to the minimum number of activated links in the MP group.
Cause 2: The IP address of the MP group is incorrect.
a.
In the interface view, run the display this or display this interface command to check
the IP address of the MP group.

Troubleshooting
If static routes are correctly configured but the commissioning device fails to receive some or
all routes, complete the following:
1.
Check that static route parameters are correctly configured.
Run the display current-configuration | include route-static command to check whether
static route parameters are correct and destination addresses, outbound interfaces, and next
hops of IPv4 static routes are configured.
2.
Check that the precedence of static routes is correctly configured.
Run the display ip routing-table command to check the precedence of static routes in the
IPv4 routing table.
The precedence of static routes is 60 by default, being lower than OSPF routes (10) and
IS-IS routes (15). Therefore, if OSPF or IS-IS is also configured, to make static routes take
effect, run the ip route-static default-preference preference command to set the default
precedence of static routes to be higher than that of OSPF routes or IS-IS routes before
configuring static routes. The smaller the preference value, the higher the preference.
3.
If the fault persists, collect the following information and contact Huawei technical support
personnel.

The boldfaced items in the command output show the OSPF neighbor information. Then check
the number of neighbors, whether or not the neighbor relationships are in the Full state (indicating
that the neighbors have finished LSDB synchronization and established the Full adjacency) and
whether or not the neighbors can remain in the Up state for a long time. If a neighbor stays in
the Up state for a short period of time, the OSPF neighbor relationship has been recently
interrupted. Pay attention to such a symptom.
Step 2 Run the display ospf routing command on the commissioning device to view information about
the OSPF routing table.

Troubleshooting
If the OSPF neighbor relationship is Down after OSPF is configured, complete the following:
1.
Check logs to find the cause of the Down OSPF neighbor relationship.
Run the display logbuffer command to view the following log information:
NBR_DOWN_REASON(l): Neighbor state leaves full or changed to Down. (ProcessId=
[USHORT], NeighborRouterId=[IPADDR], NeighborAreaId=[ULONG],
NeighborInterface=[STRING],NeighborDownImmediate reason=[STRING],
NeighborDownPrimeReason=[STRING], NeighborChangeTime=[STRING])
Check the NeighborDownImmediate reason field which records the cause of the Down
OSPF neighbor relationship. Possible causes are as follows:
l Neighbor Down Due to Inactivity
It indicates that the local end does not receive any Hello packet from its neighbor within
the deadtime, and hence the OSPF neighbor relationship becomes Down. In this case,
go to Step 2.
l Neighbor Down Due to Kill Neighbor
It indicates that the interface or BFD session is in the Down state, or the reset ospf
process command is run and hence the OSPF neighbor relationship becomes Down. In
this case, check the NeighborDownPrimeReason field to find the specific cause of the
fault.
– If the NeighborDownPrimeReason field displays Physical Interface State
Change, the interface status has changed. In this case, run the display interface
[ interface-type [ interface-number ] ] command to check the interface status, and
then rectify the interface fault.
– If the NeighborDownPrimeReason field displays OSPF Process Reset, the reset
ospf process command has been executed. Whether or not this command has been
run can be ensured by checking the operation records or log information.
– If the NeighborDownPrimeReason field displays BFD Session Down, the BFD
session status has become Down. In this case, rectify the BFD fault.
l Neighbor Down Due to 1-Wayhello Received or Neighbor Down Due to SequenceNum
Mismatch
It indicates that the OSPF status on the remote end becomes Down before the remote
end sends a 1-Way Hello packet to the local end, causing the OSPF status on the local
end to become Down as well. In this case, rectify the fault on the remote end.

l In other cases, go to Step 9.
2.
Check that the link between the two ends works normally.
Check that the link between the two ends is working normally, including the transmission
devices. If the link works properly, go to Step 3.
3.
Check that the CPU usage is within the normal range.
Check whether or not the CPU usage on the MPU or LPU of the faulty device is too high.
If the CPU usage is too high, OSPF fails to receive and send protocol packets, causing the
neighbor relationship to flap. In this case, rectify the high CPU usage fault. If the CPU
usage is within the normal range, go to Step 4.
4.
Check that the interface status is Up.
Run the display interface [ interface-type [ interface-number ] ] command to check the
physical status of the interface. If the physical status of the interface is Down, rectify the
interface fault.
If the physical status of the interface is Up, run the display ospf interface command to
check that the OSPF status of the interface is Up.

l If the OSPF status of the interface is normal (for example, DR, BDR, DR Other, or P2P),
go to Step 5.
5.
Check that the IP addresses of the two ends are on the same network segment.
l If the IP addresses of the two ends are on different network segments, modify the IP
address of one end.
l If the IP addresses of the two ends are on the same network segment, go to Step 6.
6.
Check that MTUs of the interfaces on both ends are consistent.
If ospf mtu-enable is enabled on the interfaces, the interface MTUs must be consistent.
Otherwise, OSPF neighbors cannot negotiate with each other successfully.
l If MTUs of the interfaces on both ends are inconsistent, run the mtu mtu command in
the interface view to change MTUs of the interfaces to be consistent on both ends.
l If the MTUs of the interfaces on both ends are consistent, go to Step 7.
7.
Check that there is at least one interface whose priority is not 0.
On the broadcast and NBMA networks, there should be at least one interface whose priority
is not 0, which ensures that a DR is elected correctly. Otherwise, the state of the OSPF
neighbor relationship can only reach 2-Way.
Run the display ospf interface command to view the interface priority.

l Check the Bad authentication type field. If the value of this field continually
increases, the OSPF authentication types of the two ends that establish the neighbor
relationship are different. In this case, you need to set the same authentication type
for both ends.
l Check the Hello timer mismatch field. If the value of this field continually
increases, the values of the Hello timers on the two ends that establish the neighbor
relationship are different. In this case, you need to check the interface
configurations of the two ends and set the same value for their Hello timers.
l Check the Dead timer mismatch field. If the value of this field continually
increases, the dead timers on the two ends that establish the neighbor relationship
are different. In this case, you need to check the interface configurations of the two
ends and set the same value for their dead timers.
l Check the Extern option mismatch field. If the value of this field continually
increases, the area types of the two ends that establish the neighbor relationship
are different (the area type of one device is common area, and that of the other
device is stub area or NSSA). In this case, you need to set the same area type for
both ends.
If the fault persists, proceed to Step 9.

Troubleshooting
If the IS-IS neighbor relationship cannot be established after IS-IS is configured, complete the
following:
1.
Check that IS-IS can receive and send Hello packets properly.
Run the display isis statistics packet [ interface interface-type interface-number ]
command to check that IS-IS can normally receive and send Hello packets.
NOTE
The default interval at which IS-IS sends Hello packets is 10s. Therefore, run this command every
10s to check whether or not the packet statistics increase.
On a broadcast interface, IS-IS Hello packets have IS-IS levels, and therefore you can view Hello
packet statistics based on the levels of established neighbor relationships. On a P2P interface, IS-IS
Hello packets have no IS-IS levels and are recorded as L2 IIH packets.
l If the number of received Hello packets does not increase for a certain period, check
whether or not packet loss has occurred at the lower layer or at the link between the two
ends.
l If the number of received Hello packets increases gradually, perform the following
operations based on interface types:

– If the interfaces on both ends are trunk interfaces, check that the numbers of the
trunk member interfaces in the Up state are the same on both ends.
– If the interfaces on both ends are not trunk interfaces, go to next step.
2.
Check that the interface status is Up.
Run the display ip interface [ interface-type interface-number ] command to check the
status of a specified interface.
l If the interface status is not Up, rectify the interface fault. For detailed troubleshooting
procedures, see "Interface & Physical Connection Troubleshooting" and "Layer 2
Network Troubleshooting."
l If the interface status is Up, go to next step.
3.
Check the status of IS-IS interfaces.
Run the display isis interface command to check the status of the interfaces enabled with
IS-IS.
l If the interface status is Mtu:Dn/Lnk:Up/IP:Up, run the display currentconfiguration interface interface-type [ interface-number ] command to check the
MTUs of the interfaces. Run the display current-configuration configuration isis
command to check the LSP length configured in the IS-IS process. On a P2P interface,
the LSP length should not be greater than the MTU. On a broadcast interface, the value
obtained by subtracting the LSP length from the MTU should be greater than or equal
to 3. If these conditions are not met, change the MTU of the interface or the LSP length.
l If the interface status is Down, run the display current-configuration configuration
isis command to check the configuration of the IS-IS process. Check that the NET is
configured in the IS-IS process. If not, configure the NET in the IS-IS process.
l If the interface status is Mtu:Up/Lnk:Dn/IP:Dn, check that IS-IS interfaces are
configured with IP addresses.
l If the interface status is Up, go to next step.
4.
Check that the IP addresses of the two ends are on the same network segment.
l If the IP addresses of the two ends are on different network segments, modify the IP
address of one end.
l If the IP addresses of the two ends are on the same network segment, go to next step.
5.
Check that both ends are configured with different system IDs.
Run the display current-configuration configuration isis command to check whether or
not the system IDs of the two ends are the same.
l If the system IDs of the two ends are the same, set different system IDs for each end.
l If the system IDs of the two ends are different, go to next step.
6.
Check that the IS-IS levels of the two ends are consistent.
Run the display current-configuration configuration isis | include is-level command to
check the levels of the IS-IS processes on both ends. Then, run the display currentconfiguration interface interface-type interface-number | include isis circuit-level
command to check whether or not the IS-IS levels of the interfaces at both ends are
consistent. The IS-IS neighbor relationship can only be established when the IS-IS levels
of the two interfaces are consistent.

l If the IS-IS levels of the interfaces at both ends are inconsistent, run the is-level
command in the IS-IS view to change the IS-IS level of one end, or run the isis circuitlevel command in the interface view to change the IS-IS level of the interface.
l If the IS-IS levels of the interfaces at both ends are consistent, go to next step.
7.
Check that the area addresses of the two ends are the same.
When the area addresses of the two ends are different, the alarm isisAreaMismatch is
generated.
NOTE
If the two ends establish a Level-1 neighbor relationship, ensure that they are both in the same area.
An IS-IS process can be configured with a maximum of three area addresses. As long as one of the
area addresses of the local IS-IS process is the same as one of the area addresses of the remote IS-IS
process, the Level-1 neighbor relationship can be established.
When an IS-IS Level-2 neighbor relationship is established between two ends, you do not need to
determine whether or not the area addresses of the two ends are the same.
l If the area addresses of the two ends are different, run the network-entity command in
the IS-IS view to set the same area address for both ends.
l If the area addresses of the two ends are the same, go to next step.
8.
Check that the authentication configurations on the two ends are the same.
If the authentication modes configured on the two ends are different, the alarm
isisAuthenticationTypeFailure or isisAuthenticationFailure is generated.
Run the display current-configuration interface interface-type interface-number |
include isis authentication-mode command to check IS-IS authentication configurations
on the interfaces of the two ends.
l If the authentication modes configured on both are different, run the isis authenticationmode command in the IS-IS interface view on both ends to set the same authentication
mode.
l If the authentication password configured on both are different, run the isis
authentication-mode command in the IS-IS interface view on both ends to set the same
authentication password.
l If the authentication modes configured on both ends are the same, go to next step.

Troubleshooting
If the BGP peer relationship cannot be established on a BGP-deployed network, complete the
following:
1.
Run the ping command to check that BGP peers can ping each other successfully.
l If they can ping each other successfully, it indicates that there are available routes
between the BGP peers and that link transmission is normal. Proceed to Step 2.
NOTE
Run the ping -a source-ip-address -s packetsize host command to detect the connectivity of each
end. Because the source address is specified in this command, you can check whether or not
routes between the two ends are accessible. By specifying the size of a Ping packet, you can also
check whether or not long Ping packets can be normally transmitted over the link.
l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the
ATNMulti-service Access Equipment Troubleshooting to find whether or not the
routing tables on each end have available routes to each other.
2.
Check that no ACL is configured to filter packets whose destination port is TCP port 179.
Run the display acl all command on both ends to check whether or not an ACL is configured
to filter packets whose destination port is TCP port 179.
<HUAWEI> display acl all
Total nonempty ACL number is 1
Advanced ACL 3001, 2 rules
Acl's step is 5
rule 5 deny tcp source-port eq bgp
rule 10 deny tcp destination-port eq bgp
l If an ACL is configured to filter packets whose destination port is TCP port 179, delete
the ACL configuration.

l If no ACL is configured to filter packets whose destination port is TCP port 179, go to
Step 3.
3.
Check that the peer router ID does not conflict with the local router ID.
Check information about BGP peers to ensure that their router IDs do not conflict. For
example, if the IPv4 unicast peer relationship fails to be established, you can run the display
bgp peer command to check whether or not the peer router ID conflicts with the local router
ID. Use the following command output as an example:

NOTE
To check information about BGP peers in the BGP-VPNv4 address family or the BGP-VPN instance
address family, you can run the display bgp vpnv4 all peer command.
l If the peer router ID conflicts with the local router ID, run the router id command in
the BGP view to modify the router IDs to agree. Generally, a loopback interface address
is used as the local router ID.
l If the peer router ID does not conflict with the local router ID, go to Step 4.
4.
Check that the peer AS number is configured correctly.
Run the display bgp peer command on each end to check that the displayed peer AS
number is the same as that of the remote end.

l If the peer AS number is configured incorrectly, change it to be the same as that of the
remote end.
l If the peer AS number is configured correctly, go to Step 5.
5.
Check whether or not BGP configurations affect the establishment of the BGP peer
relationship.
Run the display current-configuration configuration bgp command to check BGP
configurations.
Table 5-1 describes the checklist for BGP configurations.

Item
Description
peer connect-interface interfacetype interface-number
If two ends use loopback interfaces to establish
the BGP peer relationship, you need to run the
peer connect-interface command to specify
the associated loopback interface as the source
interface that sends BGP packets.
peer route-limit limit
If the peer route-limit limit limit command is
configured, check whether or not the number of
routes sent by the peer exceeds the limit that is
specified by limit. If it is exceeded, you need to
reduce the number of routes sent from the peer,
and run the reset bgp ip-address command to
reset the BGP peer relationship and trigger the
reestablishment of the BGP peer relationship.
peer ignore
If the peer ignore command is configured on
the peer, it indicates that the peer is not required
to establish the BGP peer relationship with the
local end temporarily. To establish the BGP
peer relationship between the remote peer and
local peer, run the undo peer ignore command
on the peer.
peer enable
Check that the address family capabilities of the
two ends match. For example, before
establishing the BGP VPNv4 peer relationship,
you need to configure the peer enable
command in the BGP-VPNv4 address families
of the two ends. If the peer enable command is
only configured on one end, the BGP peer
relationship of the other end is displayed as No
neg.

Troubleshooting
If the established LDP session is in the Down state on an LDP-deployed network, complete the
following:
1.
Check whether the interface on which the LDP session is established is shut down.
Run the display this command in the interface view. If the command output contains
shutdown, the interface is shut down.
l If the interface is shut down, run the undo shutdown command in the interface view
to start the interface.
l If the interface is not shut down, go to Step 2.
2.
Check whether commands for deleting MPLS configurations have been executed.
Run the display current-configuration command to check whether commands for deleting
MPLS configurations have been executed.
l If the command output does not contain mpls, MPLS is disabled.
l If the command output does not contain mpls ldp, MPLS LDP is disabled.
l If the command output does not contain mpls ldp remote peer, the session established
with the remote LDP peer has been deleted.
l If any command for deleting MPLS configurations has been run, run corresponding
commands to restore the deleted configurations.
l If no command for deleting MPLS configurations has been run but the fault persists, go
to Step 3.

Check that routes are available.
Run the display ip routing-table command and check the Destination/Mask field in the
command output to find out whether there is a route to the peer device. If there is no route
to the peer device, the TCP connection cannot be established.
l If the route to the peer device is unreachable, follow the procedure described in "The
Ping Operation Fails" in the ATNMulti-service Access Equipment Troubleshooting to
rectify the IGP route fault.
l If the route to the peer device is reachable, go to Step 4.
4.
Check whether an LDP Hello-hold timer expires.
Run the display mpls ldp interface command to check that both ends of the LDP session
can send Hello messages. It is recommended that the display mpls ldp interface command
be run every 3 seconds. If the statistics on sent or received messages remain unchanged,
the transmission of Hello messages is abnormal, and the Hello-hold timer expires.
l If the Hello-hold timer expires, see the troubleshooting of high CPU usage.
l If the Hello-hold timer does not expire, go to Step 5.
5.
Check whether the LDP Keepalive-hold timer expires.
Run the display mpls ldp session command to check that both ends of the LDP session
can send Keepalive messages. It is recommended that the display mpls ldp session
command be run every 5 seconds. If the statistics on sent or received messages remain
unchanged, the transmission of Keepalive messages is abnormal, and the Keepalive-hold
timer expires.
l If the Keepalive-hold timer expires, follow the procedure described in "The Ping
Operation Fails" in the ATNMulti-service Access Equipment Troubleshooting to rectify
the fault in message forwarding.
l If the Keepalive-hold timer does not expire, go to Step 6.

Troubleshooting
If the established TE tunnel is in the Down state on a TE-deployed network, complete the
following:
1.
Check that the commit command has been executed to commit tunnel configurations.
Run the display current-configuration command on the ingress that is configured with
the TE tunnel.
l If the commit command has not been executed, run it in the tunnel view.
l If the commit command has been executed in the tunnel view, go to Step 2.
2.
Check that CSPF has been successfully calculating paths.
Run the display mpls te cspf destination ip-address explicit-path path-name command
on the TE tunnel ingress. If command output is displayed, CSPF has been successfully
calculating paths; if no command output is displayed, CSPF failed to calculate a path.
l If CSPF failed to calculate a path, check that routes to the destination of the TE tunnel
exist.
– If no route exists, follow the procedure described in "The Ping Operation Fails" in
the ATNMulti-service Access Equipment Troubleshooting to rectify the route fault.
– If reachable routes exist and they satisfy the requirements to establish a TE tunnel,
rectify the fault by referring to the section "CSPF Calculation Fails."
l If CSPF has been successfully calculating paths but the fault persists, go to Step 3.
3.
Check that RSVP is enabled on every device along the TE tunnel.
The command output of display mpls te cspf destination ip-address explicit-path pathname in Step 2 contains a series of IP addresses. These IP addresses indicate the hops along
the TE tunnel. On the interface mapped to each IP address, run the display currentconfiguration interface interface-name command to check if RSVP is enabled.
l If an interface is not enabled with RSVP, enable RSVP on the interface.
l If all interfaces are enabled with RSVP but the fault persists, go to Step 4.
4.
Check that devices along the TE tunnel have been successfully exchanging RSVP Path and
Resv messages.
Run the display mpls te tunnel-interface command on the TE tunnel ingress and check
fields Ingress LSR ID, LSP ID, and Session ID in the command output. In Step 3, LSR
A, LSR B, and LSR C represent the nodes along the TE tunnel.
Complete the following to check that the RSVP Path message and RSVP Resv message
are correctly transmitted:
l Check that RSVP Path messages are correctly sent and received on every node along
the LSP in the sending direction (LSR A -> LSR B -> LSR C).
Run the display mpls rsvp-te psb-content command on every node the RSVP Path
message travels through.
– If the command output is not empty on any node, it can be concluded that RSVP
Path messages are correctly sent and received between these nodes.

– If the command output is empty on a node, it can be concluded that the node fails
to receive RSVP Path messages from the upstream node.
l Check that RSVP Resv messages are correctly transmitted in the sending direction (LSR
C -> LSR B -> LSR A).
Run the display mpls rsvp-te rsb-content command on every node the RSVP Resv
message travels through.
– If the command output is not empty on any node, it can be concluded that RSVP
Resv messages are correctly transmitted.
– If the command output is empty on a node, it can be concluded that the node fails
to receive RSVP Resv messages from the upstream node.
l If messages fail to be properly exchanged, follow the procedure described in "The Ping
Operation Fails" in the ATNMulti-service Access Equipment Troubleshooting to rectify
the message forwarding fault.
l If messages are properly exchanged but the fault persists, go to Step 5.

Check that the sent and received BGP routes are correct. First check whether the routes sent by
the PE are correct, meaning whether some necessary routes are not sent but some unnecessary
routes are sent. Then do the same for the routes received from the peer PE.
Step 4 Run the display ip routing-table vpn-instance command on the commissioning device to view
the routing table of the VPN instance.

The command output shows whether the received BGP routes are injected into the routing table
of the VPN instance. If BGP routes are received but are not injected into the routing table of the
VPN instance, the probable cause is that the public network tunnel is not established, or the
routes are filtered by a routing policy. The boldfaced items in the command output show the
route to the interface on the remote CE.
Step 5 Run the ping command on CE1 to test the connectivity of the link between CE1 and CE2.

The preceding command output shows that two CEs in the same VPN can communicate with
each other.
----End
Troubleshooting
If BGP traffic in the VPN is interrupted, complete the following:
1.
Check that next hops of routes are reachable.
Run the display bgp vpnv4 vpn-instance vpn-instance-name routing-table ipv4address [ mask | mask-length ] command on the PE that sends routes (the local PE) to check
that the target route exists. ipv4-address specifies the prefix of the target route.
l If the target route does not exist, check whether the route of a CE is advertised to the
local PE.
l If the target route exists, check that it is active. The following is an example:
Assume that the target route is a route to 1.1.1.1/32. The following command output shows
that this route is active and selected. The original next hop and iterated next hop of this
route are 3.3.3.3 and 20.1.1.2 respectively.

l If the target route is inactive, check whether there is a route to the original next hop in
the IP routing table. If there is no route to the original next hop, the BGP route is not
advertised, because its next hop is unreachable. Then, find out why there is no route to
the original next hop (this fault is generally associated with IGP or static routes).
l If the target route is active but not selected, check whether there is a route with a higher
protocol preference in the IP routing table. If there is a route with a higher protocol
preference, import it into BGP or adjust its protocol preference. If there is no route with
a higher protocol preference, contact Huawei technical support personnel.
NOTE
In the BGP routing table, multiple routes may have the same prefix. One of these routes can be
selected at most, and only the selected route is added to the IP routing table and sent to the peer.
When an optimal route needs to be selected from among BGP routes and other protocol routes,
the route with the highest protocol preference is selected.
l If the target route is active but not selected, contact Huawei technical support personnel.
NOTE
If there are active BGP routes, one of them is preferred.
l If the target route is active and selected but there is no information indicating that this
route is sent to the remote PE, perform Step 2 to check the outbound policy applied to
the local PE.
Run the display bgp vpnv4 all routing-table network { mask | mask-length } command
on the remote PE to check that it has received the target route.
– If the remote PE has received the target route, perform Step 1 again to check whether
the next hop of the route is reachable and whether this route is selected.
– If the remote PE has not received the target route, perform Step 2 to check the
inbound policy applied to the remote PE.
2.
Check that the routing policies are configured correctly.
Run the display current-configuration configuration bgp command on the local PE and
remote PE to check that inbound and outbound policies are configured.
NOTE
You only need to focus on peers of the BGP-VPNv4 address family or BGP-VPN instance address
family when private network traffic is interrupted.

5.
Check that the number of labels does not exceed the limit.
Check that MPLS is enabled on the local PE. Then, run the display bgp vpnv4 all routingtable ipv4-address [ mask | mask-length ] command to check whether the target route has
been assigned a VPN label.
If there is no Label information field in the command output, labels may be insufficient.
As a result, the target route is not assigned a label and is not advertised to the peer.

l If labels are insufficient, run the apply-label per-instance command in the VPN
instance view to configure the device to assign a label to each instance to save labels.
You can also configure route summarization to reduce the number of routes.
l If labels are sufficient, go to Step 6.
6.
Check that the number of routes does not exceed the limit.
Run the display current-configuration configuration bgp | include peer destinationaddress command and the display current-configuration configuration bgp | include
peer group-name command (if the peer is added to a peer group) on the remote PE to check
whether the limit on the number of routes to be received is configured on the remote PE.
For example, if the limit is set to 5, subsequent routes are dropped and a log is recorded
after the remote PE receives five routes from the local PE at 1.1.1.1.
<HUAWEI> display current-configuration configuration bgp | include peer
1.1.1.1

If the peer is added to a peer group, there may be no configurations about the route limit
in the command output.
<HUAWEI> display current-configuration configuration bgp | include peer
1.1.1.1
peer 1.1.1.1 as-number 100

l If the Send Packets value does not increase, go to Step 4.
l If both the Received Packets and Send Packets values increase properly, go to Step 7.
l If none of the Received Packets, Send Packets, Received Bad Packets, and Send Bad
Packets values increases, go to Step 5.
l If the Down Count value increases, the BFD session flaps. In this case, go to Step 5.
3.
Run the display bfd statistics session all command repeatedly to check that the Received
Bad Packets value increases properly.
l If the Received Bad Packets value increases, the local end receives but discards the
BFD packets sent from the remote end. In this case, go to Step 7.
l If the Received Bad Packets value does not increase, the local end does not receive
BFD packets. In this case, go to Step 5.
4.
Run the display bfd statistics session all command repeatedly to check that the Send Bad
Packets value increases properly.
l If the Send Bad Packets value increases, the BFD packets are sent but discarded. In
this case, go to Step 7.
l If the Send Bad Packets value does not increase, the local end does not send BFD
packets to the remote end. In this case, go to Step 5.
5.
Run the display bfd statistics session all command repeatedly. If the BFD session still
does not go Up, run the ping command on one end to ping the other end of the BFD session.
l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the
ATNMulti-service Access Equipment Troubleshooting to rectify the packet forwarding
fault.
l If the ping succeeds, go to Step 6.
6.
Run the display current-configuration configuration bfd-session command to check the
min-tx-interval and min-rx-interval values and determine whether or not the detection
time value is larger than the delay value.
l If the detection time value is smaller than the delay value, run the detect-multiplier,
min-rx-interval, or min-tx-interval command to change the detection time value of
the BFD session to be larger than the delay value.
l If the detection time value of the BFD session is larger than the delay value, go to Step
7.

If the ATN device is in the downstream direction, it must synchronize to the clock of the upstream
device. In this case, check the text in bold displayed in the command output to determine whether
the clock source is correct and whether the ATN device synchronizes to this clock source. If the
clock source is empty or not the expected one, ensure that the clock source is correctly configured
for the ATN device. If the 2M external clock loop is used, ensure that the 2M-1 or 2M-2 clock
source is correctly configured for the ATN device and the ATN device has correctly
synchronized to the clock source.
Step 2 On the ATN device, run the display ptp all command to view the IEEE 1588v2 time information.

If the ATN device is in the downstream direction, it must synchronize to the time of the upstream
device through its external time interface. In this case, check the text in bold displayed in the
command output. In this example, the ATN device is expected to synchronize to the BITS0 time
source. Therefore, ensure that the BITS0 source is in normal input state and is correctly
synchronized. If the bold text shows the time source is BITS0 but is not locked by the ATN
device, wait for 5 minutes and then check it again. If the BITS0 clock source is still unlocked,
check whether the clock source is normal. If not, configure a normal clock source for the ATN
device.
Step 3 On the ATN device, run the display ptp-adaptive all command to view the IEEE 1588ACR

If the ATN device is in the downstream direction, it must synchronize to the clock of the upstream
device. In this case, check the text in bold displayed in the command output. In this example,
the ATN device is expected to synchronize to the 1588ACR clock of the upstream device. Check
whether the ATN device has successfully negotiated with the clock servers and is in stable state.
If the state is stable, the ATN device has successfully synchronized to the clock of the upstream
device.
