If the interface is in the "Shutdown/Down" state, as shown in the previous example, perform the
Step 5
following tasks:
Verify that the status of the interface is "shutdown":
a.
RP/0/RP0/CPU0:router# show running interface POS0/2/0/3
interface pos0/2/0/3
shutdown
keepalive disable
!
Bring the interface up with the following commands:
b.
RP/0/RP0/CPU0:router(config)# controller pos 0/2/0/3
RP/0/RP0/CPU0:router(config-sonet)# no shutdown
RP/0/RP0/CPU0:router(config-sonet)# commit
RP/0/RP0/CPU0:router(config-sonet)# exit
RP/0/RP0/CPU0:router(config)# interface pos 0/2/0/3
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#
If the interface state is still displayed as "Down," verify that the physical cable connections are correctly
Step 6
installed. The following message indicates that the interface either has a bad connection or no
connection:
LC/0/0/1:Sep 29 15:31:12.921 : plim_4p_oc192[183]: %SONET-4-
ALARM : SONET0_1_1_0: SLOS
Verify again that the interface is up by entering the show ipv4 interface brief command:
Step 7
RP/0/RP0/CPU0:router# show ipv4 interface brief
