Step 5 If the interface is in the “Shutdown/Down” state, as shown in the previous example, perform the following tasks:

a.Verify that the status of the interface is “Shutdown”:

RP/0/RP0/CPU0:router# show running-config interface POS0/2/0/3

interface pos0/2/0/3 shutdown keepalive disable

!

b.Bring the interface up with the following commands:

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#

Step 6	If the interface state is still displayed as “Down,” verify that the physical cable connections are correctly
	installed. The following message indicates that the interface has either 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
Step 7	Verify again that the interface is up by entering the show ipv4 interface brief command:
	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
