Introduction
1.1
Overview
Purpose and Use
This manual describes the technical characteristics, applications, installation and
operation of the HS-ETH/SW Ethernet bridge I/O module for the Megaplex-2100
and Megaplex-2104 modular E1/T1 multiplexer systems.
Note
In this manual, the generic term Megaplex is used when the information is
applicable to both the Megaplex-2100 and Megaplex-2104 chassis types. The
complete designation is used only for information applicable to a specific
equipment version.
The HS-ETH/SW has four independent LAN ports, all handled by an internal
Ethernet switch. The connection to the WAN is made over timeslot bundles
routed to the main links. The number of WAN ports is configured by the user (up
to a maximum of 16).
Main Features
LAN Ports
The four LAN ports have 10/100BaseT Ethernet interfaces that use
auto-negotiation for plug-and-play Ethernet connectivity. Each Ethernet interface
is terminated in an eight-pin RJ-45 connector.
Traffic Handling
The LAN ports are connected to an Ethernet switch with full compliance with the
IEEE 802.3/Ethernet V.2 standards. The switch supports port-based and IEEE
802.1Q tag-based VLANs, with characteristics configurable on a per-port basis.
The switch operates in the IEEE 802.1Q shared VLAN learning mode (SVL): this
means that any MAC address learned in one VLAN is also used for forwarding
decisions affecting that address in all the other VLANs.
The maximum frame size supported by the switch is 1536 bytes.
HS-ETH/SW
MP-2100/2104 Ver. 11
Overview
1-1
Chapter 1 Introduction
Installation and Operation Manual
The algorithm used for frame forwarding can be configured in accordance with
the application requirements:
•
Bridge only
•
Bridge and Spanning Tree Protocol (STP), with selection between standard
STP and Rapid STP (RSTP)
•
IP subnet switching.
The WAN side of the Ethernet switch is connected to a packet processor, that
supports transmission to up to 16 separate WAN destinations over separate,
independent timeslot bundles that serve as WAN ports. Bandwidth can be
assigned to each WAN port in multiples of 64 kbps, up to 31 × 64 kbps per port
(but not more than 62 × 64 kbps for the whole module), in accordance with the
desired throughput. The timeslot bundle of each WAN port can be routed,
through the internal TDM buses, to any main link port.
The packet processor can also provide Layer 3 subnet switching for any WAN
port: the port to be used for reaching a specific subnet is configured by means of
static routes (up to 100 routes can be defined, each one associated with a
specific port of HS-ETH/SW modules installed in the chassis).
A default gateway can also be defined, together with default ports for sending
traffic to destinations for which the path is unknown.
HS-ETH/SW is fully compatible with other bridges/routers which support the HDLC
protocol on the WAN.
Note
The HS-ETH/SW module handles only IP traffic. Even in bridge mode, it needs a
MAC header and a valid IP header in order to operate. However, in the
point-to-point service, when IP is not used, you can add VLAN in the ingress port
and remove it on the remote egress port.
Management Access
Any one of the external LAN ports of one HS-ETH/SW module installed in the
Megaplex can be used to support management communication with the Megaplex
management subsystem, as an alternative to the Ethernet port of the CL module.
The HS-ETH/SW module also supports the use of management VLANs.

Installation and Operation Manual
Chapter 1 Introduction
Figure 1-1. Typical Point-to-Point HS-ETH/SW Application
Each port of a HS-ETH/SW module operates independently of the other ports,
therefore a HS-ETH/SW module can simultaneously provide several bridging
connections, each supported by an internal WAN port. The WAN ports can either
use different timeslots on the same Megaplex main link, or timeslots on different
main links of the same Megaplex chassis. Therefore, the required connectivity is
provided over legacy TDM links.
The main link bandwidth assigned to each HS-ETH/SW WAN port can be selected
in 64 kbps steps, in accordance with the volume of traffic expected between the
nodes attached to two LANs, and the requirements of the applications running
on these nodes.
Another application for HS-ETH/SW modules is to provide the connectivity needed
to distribute the video generated by VID modules to multiple locations, as shown
in Figure 1-2.

Figure 1-3 shows an application that uses the IP subnet switching feature of
HS-ETH/SW modules to provide Layer 3 routing services.

TDM Bus Interfaces
The HS-ETH/SW module has four independent TDM bus interfaces, one for each
Megaplex TDM bus. Each TDM bus interface is used to connect timeslots from the
corresponding bus to the internal routing matrix of the HS-ETH/SW module, in
accordance with the commands received from the CL module.
Routing Matrix
The HS-ETH/SW module includes a routing matrix that controls the signal flow
between the four TDM buses and the 16 WAN-side internal ports of the packet
processor (these internal ports are designated IN2 to IN17). This enables
connecting any internal WAN port to any main link port in the Megaplex chassis.
Matrix routing is user-programmable, under the control of the CL module and
enables connecting any timeslot to any port.

Installation and Operation Manual
Chapter 1 Introduction
The user can configure the bandwidth (number of timeslots) assigned to each
internal port in multiples of 64 kbps (the range is 1 to 31, corresponding to
throughputs of 64 to 1984 kbps). Note however the following restrictions:
•
The maximum number of timeslots that can be connected from any internal
WAN port to TDM buses is 31
•
The total number of timeslots that can be connected from all the module
internal WAN ports to TDM buses is up to 62 (corresponding to a maximum
data rate of 3968 kbps)
•
The maximum number of timeslots that can be actually connected to any
main link port depends on the port type and framing (E1 or T1).
Packet Processor
Traffic Sources
The packet processor handles traffic from the following sources:
•
One internal port from the Ethernet switch, designated IN1. This port carries
traffic received and/or transmitted through the four external Ethernet ports
of the HS-ETH/SW module, after processing by the Ethernet switch.
•
Up to 16 internal WAN ports, designated IN2 to IN17, which are connected by
the routing matrix to the internal TDM buses. These ports carry the traffic
directed to the WAN. The number of active ports is configured by the user.
•
The IP connectivity test subsystem, which can be used to test IP connectivity
between the HS-ETH/SW module and the desired remote IP host using the
ping function.
•
Megaplex management subsystem, located on the CL module.
Packet Processor Functions
The main function of the packet processor is to manage the flow of packets
through the internal WAN ports, IN2 to IN17. The functions to be performed
depend on the selected mode:
•
For traffic associated with ports using the bridge mode: forwarding is
performed in accordance with the MAC address or VLAN.
•
For traffic associated with ports using the L3 subnet switching mode, the
packet processor determines the packet routing using preconfigured static
routes.
The packet processor also collects performance monitoring statistics for the
internal WAN ports, and for the traffic exchanged over the internal port IN1 with
the Ethernet switch.
Ethernet Switch Subsystem
Ethernet Switch Description
The HS-ETH/SW includes an Ethernet switch with VLAN support that fully complies
with the IEEE 802.3/Ethernet V.2 standards and has user-selectable forwarding

Chapter 1 Introduction
Installation and Operation Manual
algorithms. The switch has memory-based switch fabric with true non-blocking
switching performance.
The switch collects a wide range of performance monitoring parameters, which
can be read by management.
The Ethernet switch has five ports:
•
Four external ports, connected to the four LAN ports of the module (these
ports are designated EX1 to EX4).
•
One internal port for connection to the WAN side, designated IN1. This port is
connected to the packet processor port.
Each port is supported by an independent MAC controller that performs all the
functions required by the IEEE 802.3 protocol.
The frames passed by the MAC controller are analyzed by the ingress policy
controller of the corresponding port before being transferred to an internal
queue controller, which controls the frame egress policy and the internal egress
queues of the Ethernet switch. The queues are connected to the ports through
separate port egress policy controllers, thereby ensuring that congestion at one
port does not affect other ports.
Forwarding Algorithms
The Ethernet switch operates as a MAC bridge, that automatically learns the MAC
addresses located on each LAN and WAN port, and forwards the frames
accordingly. The Ethernet switch LAN table can store up to 1024 MAC
address/port number mappings. Only active MAC address/port number mappings
are actually stored: after a user-defined aging interval, inactive mappings are
removed from the switch memory.
When used in more complex networks, the forwarding algorithm can be extended
to include Spanning Tree Protocol (STP), where the user can select between the
basic STP version and the Rapid STP (RSTP) version. The selection is separately
made for each WAN port.
The STP parameters, which are used in common by the whole switch, can also be
selected by the user, to fine-tune the performance. To help locating forwarding
problems, the user can read the STP algorithm status and current parameter
values.
Note
1-8
When a HS-ETH/SW port is configured to use the L3 subnet switching mode, the
traffic is forwarded to the packet processor, which performs the routing
decisions in accordance with the static routes prepared for the HS-ETH/SW
module with respect to the corresponding subnet.
Functional Description
HS-ETH/SW
MP-2100/2104 Ver. 11
Installation and Operation Manual
Chapter 1 Introduction
VLAN Support
The Ethernet switch can use VLAN information to select the ports among which
traffic can be forwarded. There are two basic methods:
Note
•
Port-based VLANs. See description in the Support for Port-Based VLANs
section below
•
Tag-based VLAN switching per IEEE 802.1Q. This mode is used to handle
traffic in accordance with user-defined forwarding rules that are based on
the IEEE 802.1Q tags of the frames. See description in the Support for
802.1Q Tag-Based VLAN Switching section below.
The switch operates in the IEEE 802.1Q shared VLAN learning mode (SVL): this
means that any MAC address learned in one VLAN is also used for forwarding
decisions affecting that address in all the other defined VLANs.
Support for Port-Based VLANs
The Ethernet switch supports user-defined port-based VLANs. A port-based VLAN
is a logical group of ports defined by the user: VLAN traffic is forwarded only
among the VLAN member ports. Therefore, in addition to their functional value as
tools for controlling traffic flow, port-based VLANs are an important security tool.
The Ethernet switch enables defining port-based VLANs that include any of its
four external LAN ports, as well as the port connecting to the HS-ETH/SW packet
processor, IN1. See for example Figure 1-6, this VLAN includes the four external
LAN ports and the internal port IN1.

Figure 1-6. Example of Port-Based VLAN Functionality
Support for 802.1Q Tag-Based VLAN Switching
To support VLANs, the MAC header of Ethernet frames is increased in size by four
bytes. The additional information carried by these bytes includes a tag that
identifies the VLAN membership and frame priority. Such tags can therefore be
used to differentiate among various types of traffic in accordance with:
HS-ETH/SW
•
VLAN number (identifier – ID). The range of VLAN IDs that can be assigned by
users is 1 to 4094.
•
Priority (desired QoS). The range of priority values is 7 (highest priority) to 0
(lowest priority).
MP-2100/2104 Ver. 11
Functional Description
1-9
Chapter 1 Introduction
Installation and Operation Manual
Using the VLAN tags, the Ethernet switch can make forwarding decisions, that is,
determine the port(s) to which the frame is to be forwarded.
The user can also specify how to handle the frame tags, in accordance with the
specific requirements of each application. The available selections include:
Unmodified: the port transfers the tags of the frames forwarded to it
without change. Therefore, untagged frames egress the port as untagged
frames, and tagged frames egress the port as tagged frames (with their
original tag).
Untagged: the port removes one tag from the frames forwarded to it,
before egress. Therefore, untagged frames egress the port unmodified,
whereas tagged frames are converted to untagged frames before
egressing the port (this is performed by removing their tag and
recalculating the frame CRC). In addition, double tagged frames are
converted to tagged frames before egressing the port (this is performed
by removing the first tag and recalculating the frame CRC).
Tagged: all the frames egress the port as tagged frames. Therefore,
tagged frames egress the port unmodified, whereas untagged frames are
converted to tagged frames before egressing the port (this is performed
by adding a tag with the VLAN ID defined for the original ingress port,
and recalculating the frame CRC).
Double tagged: a tag is always added to all the frames that egress the
port.
Management Access
When the Ethernet port of the CL module is disabled, any one of the external LAN
ports of one HS-ETH/SW installed in the Megaplex can be used by management
stations to communicate with the Megaplex management subsystem.
The selected HS-ETH/SW port must be specifically configured to enable
management: in this case, the Ethernet switch transfers all the management
traffic to the CL module, via the internal control buses of the chassis.
The HS-ETH/SW module supports the use of management VLANs: the user can
enable tagging for management access and specifying the management VLAN ID
and the priority assigned to the VLAN.
Note
Only one Ethernet port in the whole Megaplex chassis may be used for
management access. Therefore, if the chassis includes an ML-IP module, it is
necessary to prevent management traffic from reaching the ML-IP ports.
External LAN Port Interface Characteristics
Each of the HS-ETH/SW module LAN ports has a 10/100BaseT Ethernet interface
for connection to user’s LANs.
Each Ethernet interface supports auto-negotiation, and therefore its data rate
(10 or 100 Mbps) and operating mode (half-duplex or full-duplex) are
automatically selected. The advertised data rate and mode are always 100 Mbps
full-duplex.
1-10
Functional Description
HS-ETH/SW
MP-2100/2104 Ver. 11
Installation and Operation Manual
Chapter 1 Introduction
Each port is terminated in an RJ-45 connector. The interface supports MDI/MDIX
crossover and therefore the port can always be connected through a “straight”
(point-to-point) cable to any other type of 10/100BaseT Ethernet port (hub or
station).
IP Connectivity Test Subsystem
This subsystem is used to test IP connectivity between the HS-ETH/SW module
and a remote IP host using the ping function, part of the ICMP protocol.
The user can select the destination IP address, the number of ping packets being
transmitted and their size, together with a time-out interval that automatically
ends pinging in case it is not possible to transmit the full number of packets
before the time-out expires (for example, because no response is received from
the destination, or the transmission of the requested number of ping packets has
not been completed).
After pinging is ended, the user can read the information collected by the
HS-ETH/SW module:
Note
•
Packet transmission reliability: the total number of ping packets sent and the
number received, and their difference (the number of lost packets)
•
Transmission delays: minimum and maximum round trip times, and the
average round trip time for the received packets.
In bridge operation, the pings are sent only to LAN ports.
Timing Subsystem
The HS-ETH/SW timing subsystem generates the various internal clock and timing
signals required by the module. These signals are derived from the Megaplex
nodal timing, and by local oscillators.
The HS-ETH/SW module cannot provide any timing signals to the Megaplex
chassis.
Management Subsystem
The local management subsystem of the HS-ETH/SW module performs two main
functions:
HS-ETH/SW
•
Controls the operation of the various circuits located on the module in
accordance with the commands received from the CL module through the
Megaplex management channel.
•
Controls the routing of traffic through the various interfaces.

Troubleshooting and
Diagnostics
This chapter describes the HS-ETH/SW module diagnostic functions. The
diagnostic functions available on the HS-ETH/SW module include:
•
Collection of performance monitoring data
•
Ping for IP connectivity testing.
These functions can be used to identify problems in the network incorporating
HS-ETH/SW modules and rapidly locate the cause of the fault: within the
HS-ETH/SW module, in its connections to the network or to a user’s equipment
unit, or in another network component.
The alarm messages generated by the HS-ETH/SW module are explained in
Appendix B of the Megaplex-2100/2104 Installation and Operation Manual.
4.1
Performance Monitoring
The HS-ETH/SW module enables the collection of transmission performance data.
The collected data enables the system administrator to monitor the transmission
performance for the payload carried by the HS-ETH/SW module, and thus the
quality of service provided to users, for statistical purposes.
In addition, when problems are reported, the collected data can be used for
diagnostic purposes, because it can help identify the source of the problem.
The following types of performance statistics are available:
•
External LAN interface performance statistics, which can be used to monitor
the traffic received handled by the external Ethernet port.
•
WAN performance statistics for each internal WAN port. Two types of WAN
port performance statistics are collected:
Performance statistics for the WAN side, which can be used to monitor
the quality of transmission through the network
Performance statistics for the Ethernet traffic sent through the WAN
port.
In addition to the performance statistics, the HS-ETH/SW also displays routing
information for the selected port.
Separate statistics are collected for the transmit and for the receive directions.

Chapter 4 Troubleshooting and Diagnostics
Installation and Operation Manual
The performance parameters are continuously collected during equipment
operation. A separate 32-bit counter is used for each performance parameter,
thereby enabling collection of data over very long intervals.
The performance parameters collected by the HS-ETH/SW module are explained
below.
External LAN Port Interface Performance Statistics
The external LAN port performance statistics are displayed using the DSP STAT CH
SS EX# or DSP CH SS # command, where SS is the HS-ETH/SW slot number and #
is the LAN port number.
Two groups of parameters are collected:
•
Receive statistics
•

Checking IP Connectivity – Ping
Overview
The HS-ETH/SW module supports the ping function, part of the ICMP protocol.
This function enables checking the IP connectivity between the HS-ETH/SW
module and a remote IP host.
When sending ping packets from the HS-ETH/SW module, the ping source address
is the module IP address defined by means of the DEF CH SS command (where SS
is the HS-ETH/SW module I/O slot).
Notes
1. You can use the ping function only for a HS-ETH/SW module that is physically
installed in the specified I/O slot.
2. On the bridge mode, the module sends and accepts pings only through its
LAN ports.
The ping parameters are defined by means of the DEF PING SS command. Using
this command, the user can select the destination IP address, the number of ping
packets being transmitted and their size, together with a time-out interval that
automatically ends the test in case the test cannot be completed before the
time-out expires (for example, because no response is received from the
destination, or the transmission of the requested number of ping packets has not
been completed).
After completing the test, use the DSP PING SS command to display the
information collected by the HS-ETH/SW module as a result of the last DEF PING
command (any previous results for the same I/O slot are erased when the DEF
PING command is executed).
Two types of information are displayed:
•
4-10
Packet transmission reliability: the total number of ping packets sent and the
number received, and their difference (the number of lost packets)

Troubleshooting
In case a problem occurs, check the displayed alarm messages and refer to
Appendix B of the Megaplex-2100/2104 Installation and Operation Manual for
their interpretation.
Note
If the problem is detected the first time the module is put into operation,
perform the following preliminary checks before proceeding:
• Check for proper module installation and correct cable connections, in
accordance with the system installation plan.
• Check the module and all the port configuration parameters in accordance
with the specific application requirements, as provided by the system
administrator.
If after collecting all the relevant information, the problem appears to be related
to the operation of the HS-ETH/SW module, perform the actions listed below,
until the problem is corrected:
•
Check IP connectivity to the required destinations using the DEF PING/DSP
PING commands.
If the test fails, there is a problem with the transmission through the IP
network (you can use the DSP STAT CH command to display the performance
monitoring statistics for the external LAN ports) or with the HS-ETH/SW
module.

If the HS-ETH/SW answers pings to its IP address, repeat the test after
carefully checking all the configuration parameters of the module and its
internal ports. If the problem persists, replace the module and check again.
•
If pings are satisfactorily answered, use the DSP STAT CH command to display
the performance monitoring statistics for the internal port IN1 and for the
internal WAN ports that are configured to carry the traffic to the to the
required destinations. Analyze the results and try to locate the problem to
