Cisco Systems Cisco IOS XR manual Configure the interfaces, as shown in the following examples

Chapter 7 Troubleshooting the Cisco IOS XR Software

Interfaces Not Coming Up

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

Interface	IP-Address	Status	Protocol
POS0/1/0/0	unassigned	Shutdown	Down
POS0/1/0/1	unassigned	Shutdown	Down
POS0/1/0/2	unassigned	Shutdown	Down
POS0/1/0/3	unassigned	Shutdown	Down
POS0/1/0/4	unassigned	Shutdown	Down
POS0/1/0/5	unassigned	Shutdown	Down
POS0/1/0/6	unassigned	Shutdown	Down
POS0/1/0/7	unassigned	Shutdown	Down
POS0/1/0/8	unassigned	Shutdown	Down
POS0/1/0/9	unassigned	Shutdown	Down
POS0/1/0/10	unassigned	Shutdown	Down
POS0/1/0/11	unassigned	Shutdown	Down
POS0/1/0/12	unassigned	Shutdown	Down
POS0/1/0/13	unassigned	Shutdown	Down
POS0/1/0/14	unassigned	Shutdown	Down
POS0/1/0/15	unassigned	Shutdown	Down
POS0/2/0/0	10.10.1.101	Down	Down
POS0/2/0/1	unassigned	Shutdown	Down
POS0/2/0/2	unassigned	Shutdown	Down
POS0/2/0/3	unassigned	Shutdown	Down
TenGigE0/3/0/0	unassigned	Shutdown	Down
TenGigE0/3/0/2	unassigned	Shutdown	Down
MgmtEth0/RP0/CPU0/0	unassigned	Shutdown	Down

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:

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
