IGX Line Configuration
This section provides information on setting up and configuring a line on an IGX node.
Setting Up a Line
Before setting up a line, finish setting up the node(s) and network trunks. You must set up lines before
provisioning voice, data, FR, or ATM services that use these lines. To set up a circuit line, use the
following procedure:
Step 1 Confirm that the desired slot contains the appropriate front and back cards (see “Cisco IGX 8400 Series
Cards”).
Step 2 Activate a line in the desired slot with the switch software upln command.
Step 3 Configure the line with the switch software cnfln command.
IGX Line Management
Line management tasks are similar to node and trunk management tasks (see “Cisco IGX 8400 Series
Nodes” and “Cisco IGX 8400 Series Trunks”). Changes to connections configured onto a line should be
carefully planned to avoid over-provisioning a node or exceeding available bandwidth.
To monitor line operation, use the following switch software commands:
• dsplns displays all lines on the node.
• dspln or dsplncnf displays configuration details for a line.
To make changes to a line configuration, use the following switch software command:
• cnfln reconfigures the line.
For information on troubleshooting a line, see the “IGX Line Troubleshooting” section on page 5-3.
IGX Line Troubleshooting
