Cisco MC3810-IGX 8400 Interworking
Feature Summary
Using the Cisco MC3810-IGX 8400 Interworking functionality, you can configure the Cisco MC3810 multiservice access concentrator to act as an access device to the IGX 8400 switch. On the Cisco MC3810, a frame trunk card (FTC) trunk port is configured to send traffic to the IGX frame trunk module (FTM) port using the network management system (NMS) protocol. Using IGX Interworking, you can scale large networks of Cisco MC3810 concentrators to IGX 8400 switches.
Note This feature module provides only configuration information for the Cisco MC3810. For information about IGX switch configuration and commands, see the Cisco WAN Switching Command Reference for version 9.1.
Benefits
Cisco MC3810-IGX 8400 Interworking provides the following benefits:
- Enables the scaling of large networks of Cisco MC3810 concentrators to IGX 8400 switches.
- Provides central site solutions that minimize equipment costs, simplify network configuration, and provide end-to-end quality of service and prioritization.
- Unlike other vendors, whose products require multiple Frame Relay Access Devices (FRADs) at a central site to de-couple voice and data, the Cisco MC3810-IGX 8400 Interworking solution allows you to terminate voice and data directly on the switch. This minimizes central site management costs by eliminating extra cabling, equipment, and space requirements.

Configuration Tasks
When you configure IGX interworking on the Cisco MC3810, you must configure one interface to serve as the FTC trunk, and then you configure the specific connections over that FTC trunk.
This section is divided into the following sections:
This section assumes that you have already configured the following:
Configuring the Cisco MC3810 FTC Management DLCI
The Cisco MC3810 FTC management data link connection identifier (DLCI) is required when configuring Cisco MC3810-IGX Interworking. You can only have one FTC management DLCI on each Cisco MC3810, but that management DLCI can also carry data and/or voice connections, or data and/or voice connections in conjunction with a Frame Relay trunk or a voice DLCI. You can configure the FTC management DLCI, the FTC Frame Relay DLCIs and FTC voice DLCIs in the following combinations:
- FTC management DLCI only (management traffic + data traffic and/or voice traffic)
- FTC management DLCI (management traffic + voice traffic) + FTC Frame Relay DLCI (data traffic)
- FTC management DLCI (management traffic + data traffic) + FTC voice DLCI (voice traffic)
- FTC management DLCI (management traffic) + FTC Frame Relay DLCI (data traffic) + FTC voice DLCI (voice traffic)
Regardless of the combination, you can configure up to 100 connections over the FTC trunk port.
Note Whether you configure data traffic and/or voice traffic on the FTC management DLCI depends on your configuration needs. For example, configuring data traffic and voice traffic on the FTC management DLCI allows you to use one DLCI, saving you money if you are charged for each DLCI. On the other hand, configuring data traffic over an FTC Frame Relay DLCI, or voice traffic over an FTC voice DLCI, allows you to isolate the traffic types for greater control and quality of service over the WAN.
To configure the Cisco MC3810 FTC management DLCI to the IGX 8400 FTM, perform the following tasks on the Cisco MC3810 beginning in configuration mode:
You have a choice of how to proceed from here. Choose one of the following options:
- To configure data connections over a separate FTC Frame Relay DLCI, proceed to the "Configuring the Cisco MC3810 FTC Frame Relay DLCI for Data Traffic (Optional)" section.
- To configure voice connections over a separate FTC voice DLCI, proceed to the "Configuring the Cisco MC3810 FTC Voice DLCI for Voice Connections (Optional)" section.
- To configure all your data and voice connections on the FTC management DLCI, perform the following tasks:
Configuring the FTC Management DLCI on the Cisco IGX 8400 Switch
For Frame Relay management DLCI connections on the IGX FTM card, use the following command syntax to add the Frame Relay management trunk connection(s) to the Cisco MC3810:
The management DLCI must match the DLCI or remote-management DLCI configured using the Cisco MC3810 ftc-trunk management-dlci command.

For information on configuring the data channels on the IGX switch, see the next section "Configuring the Data Channels on the IGX Switch".
Configuring the Data Channels on the IGX Switch
For Frame Relay connections on the IGX switch, use the following command syntax to add the Frame Relay connection(s) to the Cisco MC3810:
Note The Cisco IGX switch command syntax differs from Cisco IOS command syntax. Items in brackets (< >) are required command arguments. Items in square brackets ([ ]) are optional command arguments. These commands are based on Cisco IGX System Software Release 9.1. For more information about IGX switch configuration and commands, see the Cisco WAN Switching Command Reference.
Configuring the Cisco MC3810 FTC Voice DLCI for Voice Connections (Optional)
In addition to the FTC management DLCI, you can optionally configure an FTC voice DLCI for voice traffic. The FTC voice traffic travels over the FTC management DLCI configured in the previous section.
To configure the FTC voice DLCI to support voice connections to the IGX 8400 switch, perform the following tasks on the Cisco MC3810 beginning in configuration mode:
Repeat this procedure on each Cisco MC3810 that will send voice traffic to an IGX 8400 switch via an FTC voice DLCI.
For information on configuring the voice channels on the IGX switch, see the next section "Configuring the Voice Channels on the IGX Switch."
Configuring the Voice Channels on the IGX Switch
For voice connections on the IGX switch, use the following command syntax to add connections to the Cisco MC3810:
When configuring the voice channels, make sure the same voice compression mode that was configured on the Cisco MC3810 using the codec command is configured on the IGX voice channels. For example, if the codec command was set to g729ar8 on the Cisco MC3810 voice port, make sure that the UVM connection is also configured to support g729ar8 compression.
Note The Cisco IGX switch command syntax differs from Cisco IOS command syntax. Items in brackets (< >) are required command arguments. Items in square brackets ([ ]) are optional command arguments. These commands are based on Cisco IGX System Software Release 9.1. For more information about IGX switch configuration and commands, see the Cisco WAN Switching Command Reference.
Configuration Example
This section provides an example of how to configure the Cisco MC3810 to act as an access device to an IGX 8400 switch.
Figure 1 shows an example of two Cisco MC3810 concentrators connected to an IGX 8400 FTM, with other connections to the UVM through a PBX. The configuration examples following the figure include commands to set up the session connections, the voice PVC connections, routing through switch 0, Common Channel Signaling (CCS) frame forwarding support, the Cisco MC3810-UVM connections, and the Cisco MC3810-CVM connections.
Because the voice connections between the two Cisco MC3810 concentrators are over a Frame Relay network, VoFR dial peers must be configured on both concentrators. The session target configured on both concentrators should be the same.
