Configuration for IGX Switch Portions of the Cisco IGX 8410, 8420, and 8430 ATM-LSRs
Note IGX nodes must be set up and configured in the ATM network (including links to other nodes) before
beginning configuration for MPLS support on the node.
To configure the IGX nodes for operation, set up a virtual interface and associated partition by using the
cnfrsrc command.
To link the Cisco router to the IGX, use the addctrlr command to add the router as a VSI controller.
This allows the router label switch controller function to control the MPLS operation of a node.
For information on configuring the IGX partition, including distribution of IGX partition resources, see
the “VSI Configuration” section on page 10-34.
In this example, assume that a single external controller per node is supported, so that the partition
chosen is always 1.
Configuration for IGX 1 Portion of ATM-LSR-1
To configure the Cisco IGX 8410, 8420, and 8430 label switch routers, ATM-LSR-1 and ATM-LSR-2:
Command Description
Step 1
Check card status:
dspcds 3
The display status of the UXM card. UXM cards
that you are configuring should be “Standby” or
“Active.”
Step 2
Enable UXM interfaces:
upln 3.1
upport 3.2
In this example, line 3.1 is the link to the LSC
controller, and line 3.2 is set up as cross-connect
for use by LVCs.
Note A UXM interface is a trunk if it connects
to another switch or MGX 8220 feeder.
The VSI connection to an LSC is either a
trunk or line. Other interfaces are ports,
typically to service interfaces.
