2 New Features, Changes, and Enhancements
2.1
Virtual Cable Diagnostics (VCD)
2.1.1
General
Virtual Cable Diagnostics (VCD) is used to identify and locate faults in electrical cables, connectors
and terminations. This feature can help in identifying opens, shorts, impedance mismatch, bad
connectors, termination mismatch and bad magnetics. The feature is supported by EM2004-8TP
modules of HW Rev 08 and later.
2.1.2

Commands
get-port-vcd [ports] – display cable diagnostics.
ports = `all` or ports list: S1.D1-...-Sn.Dn, <..> for range; default : all
2.2
Auto MDI/MDIX Crossover
This feature allows connection of straight or cross-wired cables independent of the pinout (MDI or
MDIX) of the co-port (port to which the EM-2004 module is directly connected). The feature is
supported by EM2004-8TP modules of HW Rev 08 and later.
2.3
New MAC Limit Action
2.3.1
General
In previous versions, when a MAC limit is exceeded on a port there are two alternatives: 1) to
disable the port and send a trap, or 2) to send a trap without disabling the port. Now, the following
third option is available when the mac-limit is exceeded:

Process traffic of learned stations.

Discard traffic of unlearned stations.
2.3.2


Commands
set-mac-limit-mode [dbase] [mode] – Set action mode when the mac limit is
exceeded on a port.
dbase = run, nvram, or all
mode = 1 or 2 or 3
1 = Disable the port and send a trap when the MAC limit is exceeded.
2 = Send a trap when the MAC limit is exceeded.
3 = Discard traffic from unlearned stations.
get-mac-limit-mode [dbase] – Show mode of action when Mac limit exceeded on a
port.
dbase = run or nvram

2.4
Authorized Customer’s Access
2.4.1
General
In many instances customers need to have access to the provider’s management equipment
located at the customer premises. In such a situation it is most important to restrict this access to a
limited set of operations and to block any other attempt by the customer to access the provider’s
management network. In most cases the access is needed in order to retrieve management
information and statistics related to the customers interfaces. The Authorized Customer’s Access
feature enables access to the local switch but blocks any attempts to access the management
VLAN.
2.4.2
Commands

set-secured-ports [database] [ports list] [mode] – enable/disable port’s secured
properties
database type = run, nvram or all
ports list = S1.D1-...-Sn.Dn, <..> for range
mode = enable or disable
 get-secured-ports [database] – display secured ports status
database type = run, nvram or all
 set-mgmt-secondary-tag [database] [tag] - Set Secondary Management tag
database type = run, nvram or all
tag = secondary management tag { 1..4095}
 get-mgmt-secondary-tag [database] – display the secondary management’s tag
database type = run, nvram or all
 del-mgmt-secondary-tag [database] – delete the secondary management tag.
database type = run, nvram or all
related commands:
 set-user-passwd - change the console USER`s password
 del-user-passwd - delete the USER`s password
2.5
IGMP enhancements
2.5.1
Multicast Tags List
2.5.1.1
General
When the OptiSwitch functions as IGMP proxy, it sends IGMP Query every “Query Interval”
(default=1sec). In this way, the OptiSwitch maintains it’s multicast data base and forwards it to other
devices participating in IGMP. This version enables the user to specify which VLAN tags will be
multicast tags. The OptiSwitch sends IGMP Queries only to ports that are members of the specified
VLANs.
This option is useful when a large number of VLANs is defined and only a few multicast VLANs
exist.
IMPORTANT: In previous versions, IGMP queries were sent to all VLANs listed in the VLANtable. In this version, if no multicast tags list exists, IGMP queries will be sent only to the
management VLAN.

2.5.1.2

Commands
mcast-set-tag-list [tag list] – define the multicast tag list for IGMP queries.
tag list = List of multicast tags. T1,..,Tn ‘-‘ for range.

mcast-get-tag-list – display the multicast tag-list.

mcast-del-tag-list – delete the multicast tag list for IGMP queries.
2.5.2
2.5.2.1
Static Multicast Groups
General
This version supports definition of static multicast group entries. This option is most useful in cases
where Multicast servers do not support the IGMP protocol and the multicast data is flooded.
2.5.2.2

Commands
mcast-set-static-entry [ip-address] [range] [tag] – Create static multicast range
Ip-address = Ip Address of the first multicast group
range = number of multicast groups to generate
tag = tag of the multicast group.

mcast-get-static-tbl – display the static multicast table

mcast-del-static-entry [index] – delete static multicast entry
index = index of entry
2.5.3
2.5.3.1
Querier Port Modes
General
This version allows to set one of the following modes for a port:

Forced – Sends Queries forever (default)

Standard – Sends Queries until a query from a lower IP Address Querier received.

Disabled – Do not send Queries.
2.5.3.2

Commands
mcast-set-querier [ports list] [querier mode] – set Querier port mode.
ports list = S1.D1-...-Sn.Dn, <..> for range
querier mode = standard, force or disable.
mcast-get-querier – display modes of querier ports.

3 Bug Fixes and Improvements
3.1
New Management Board Recognition
This version supports recognition of the new management board (with new flash technology). The
new management board will be recognized via the CLI `sys-stat` command as: “Management card
hardware revision: i960-Jx ver. 3”.
3.2
DiffServ Port Default Command
In previous versions, the default action for a DiffServ port was “Deny”. In this version, the default
action for access-ports (port-access, vlan-access, src-ip-access…etc) can be set to “Permit” or
“Deny”. The apply action permits traffic to be forwarded even if it’s parameters do not match any
flow of it’s associated port.
3.2.1
Commands:
 ds-set-default-port-command [ports list] [mode] – set default port command
ports list = S1.D1-...-Sn.Dn, <..> for range
mode = permit or deny
 ds-get-port-cfg [ports list] – display DiffServ ports configuration
ports list = S1.D1-...-Sn.Dn, <..> for range
3.3
SFP’s Digital Information

In previous versions, displaying the SFP’s Digital Information was possible only for
CWDM compliant units. In this version the information is valid for both CWDM and
DWDM units.

In previous versions, it was possible to retrieve Digital Information only from
external calibrated SFPs. This problem is now fixed.

In previous versions, it was not possible to retrieve Digital information from GBIC’s.
This problem is now fixed.

In previous versions, intensive reading of SFP digital information caused the switch
to restart. This problem is now fixed.

In this version, when the digital information for the rx_power and tx_power is out of
range or not applicable –99 is displayed.
3.4
SAVE CONFIGURATION
This version enables saving the whole running configuration to NVRAM using just one CLI
command.
3.4.1

3.5
Command:
save-running-cfg – stores the whole run-time configuration to NVRAM.
SFP’s MIB
This version supports private SFP MIB (oasfp.mib).

3.6
DiffServ Counter Mode
In previous versions, the DiffServ counters mode (set-counter-mode) was not saved while using the
command ds-save-cfg. This is now fixed.
3.7
User Level Privilege under RADIUS
In this version, Administrators can apply user’s privilege (execute GET operations only) to users who
are accessing the OptiSwitch through a radius server. This option is available once the User’s
privilege password (defined in the OptiSwitch) and the User’s password (defined in the Radius
Server) are the same.
3.8
Flow Aging Mechanism
In previous versions, when packets in a stream, associated with a specific flow are stopped for more
than 30 seconds, in certain circumstances, the first few packets would be lost after the stream is
restarted. This problem is now fixed.
 ds-set-flows-aging-mode [mode] [aging-time] – set DiffServ flows aging mode.
mode = enable or disable
aging-time = Time in seconds for flows aging cycle. (default 30 sec)

3.9
ds-get-flows-aging-mode – display DiffServ flows aging mode
64 Bit Counters
In previous versions, reading the ifMIB objects ifHCInUcastPkts and ifHCOutUcastPkts, could
show apparently conflicting results. The problem occurs when only broadcast/multicast packets
without unicast packets flow at a high rate. This problem is now fixed.
3.10
MIB-WALK
In previous versions, MIB-WALK application sometimes failed. This problem is now fixed.
3.11
GER Module
In this version, a trap will be sent whenever the link switches from one port of the GER module to
the other.
3.12
Bridge MIB
In this version, when browsing through the SNMP, Bridge-MIB dot1dTpFdbTable is skipped by
default. This table is skipped by default since it may cause problems because it does not support
VLAN tags. To prevent skipping use the command:
set-snmp-dot1d-fdb [mode]
mode = enable or disable
Enable – do not skip dot1dTpFdbTable
Disable – skip dot1dTpFdbTable
3.13
L2PT Mode

In the previous version, in some scenarios activating the L2PT caused unstable
network operation. The problem was caused by random setting of ports to enable
operation mode following upgrade to 3.73. This problem is now fixed.

In the previous version, setting a port to L2PT mode ENABLE, caused BPDU’s and
CDP’s packets to be tunneled across the provider network. In this version a new
command enables setting the type of packets to be tunneled.
MRV International Confidential
9
set-l2pt-mode [mode] – Set L2PT mode
mode = bpdu or all
bpdu – BPDU packets will be tunneled.
all – BPDU and CDP packets will be tunneled.
get-l2pt-mode – Display L2PT mode.
IMPORTANT: After upgrading, all ports will be set to l2pt mode=DISABLE. In case
this feature is used, l2pt ports mode should be manually restored to the previous
configuration.
3.14
TFTP

In previous versions, after invoking ‘app-sw-dnld’ command, it was impossible to
configure the switch to perform any configuration upload/download operation unless
application software download was performed. In this version, the problem is
resolved by invoking the new command `init-sw-dnld`.

In previous versions, in scenarios of packet loss (due to network problems) during
upload configuration in client mode, the switch continually retransmits without
terminating the TFTP session. This problem is now fixed.

4. Known limitations
4.1.
Firmware upgrade to this version should be done from the released 3.70/3.71/3.72/3.73
versions only. If that is not possible, please consult with customer support department
before upgrading.
4.2.
When RSTP is enabled - configuring or deleting an Etherchannel when at least one of its
ports is connected (link up) is not possible (blocked by application). If modification in
Etherchannel definition is needed – first disconnect all the ports in the Etherchannel.
4.3.
GVRP protocol is not supported in this version.
4.4.
Downgrading from this version to earlier versions is not fault-proof and may require an
init-nvram procedure.
4.5.
This version is only compiled for new hardware suits. Meaning JX CPU agent of higher
than ‘1’ version and CX CPU agent of higher than ‘2’ version.
4.6.
Before using new modules with this version please make sure they are supported in it.
4.7.
Except for special cases, this version is not to be used with modules based on GT48310 / GT-48320 chipsets, to make sure you are not using these old chipsets enter the
command sys-stat. All modules revisions (in parenthesis) should be equal or greater
than 3. This is relevant to L2 modules only; All L3 modules are supported in current
software revision.
4.8.
When inserting a voice module (E1/T1 modules) that was previously configured as T1
into another OptiSwitch where it is defined as E1, there may be some noticeable noise
on voice sessions. The solution: after inserting a voice module into the OptiSwitch, it is
recommended to perform the ‘vo-line-type’ command with the required type (E1 or T1).
This operation is required only once since the updated information is saved on the
module’s flash (NVRAM) and will be used for next reboots.
