Note
Line cards in Cisco CRS-1 routers are called modular services cards (MSCs). The show platform
command output is different for Cisco CRS-1 routers and Cisco XR 12000 Series Routers. When this
command is entered in EXEC mode, the display shows only those nodes assigned to the SDR.

Step 2
Enter the show ipv4 interface brief command to verify IP address configuration and protocol status:
RP/0/RP0/CPU0:router# show ipv4 interface brief

Step 3
Configure the interfaces, as shown in the following examples.
Note
You must enter the commit command to make the new configuration part of the active running
configuration. If you end the configuration session, you are automatically prompted to commit
the changes, as shown in the second example:
configuration. If you end the configuration session, you are automatically prompted to commit
the changes, as shown in the second example:
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface pos0/2/0/1
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0
RP/0/RP0/CPU0:router(config-if)# no shutdown
RP/0/RP0/CPU0:router(config-if)# commit
RP/0/RP0/CPU0:router(config-if)# end
RP/0/RP0/CPU0:router#
RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface pos0/2/0/2
RP/0/RP0/CPU0:router(config-if)# ipv4 address 10.1.1.2 255.255.0.0
RP/0/RP0/CPU0:router(config-if)# no shutdown
RP/0/RP0/CPU0:router(config-if)# end
Uncommitted changes found, commit them? [yes]: yes
RP/0/RP0/CPU0:router#
Step 4
Enter the show ipv4 interface brief command to verify that the interfaces are “Up” in the Status column:
RP/0/RP0/CPU0:router# show ipv4 interface brief
