Interfaces Not Coming Up
	F I N A L D R A F T — C i s c o C o n f i d e n t i a l
	RP/0/RSP0/CPU0:router(config-if)# end
	RP/0/RSP0/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/RSP0/CPU0:router# show ipv4 interface brief
	Interface	IP-Address	Status	Protocol
	gi0/1/0/0	unassigned	Shutdown	Down
	gi0/1/0/1	unassigned	Shutdown	Down
	gi0/1/0/2	unassigned	Shutdown	Down
	gi0/1/0/3	unassigned	Shutdown	Down
	gi0/1/0/4	unassigned	Shutdown	Down
	gi0/1/0/5	unassigned	Shutdown	Down
	gi0/1/0/6	unassigned	Shutdown	Down
	gi0/1/0/7	unassigned	Shutdown	Down
	gi0/1/0/8	unassigned	Shutdown	Down
	gi0/1/0/9	unassigned	Shutdown	Down
	gi0/1/0/10	unassigned	Shutdown	Down
	gi0/1/0/11	unassigned	Shutdown	Down
	gi0/1/0/12	unassigned	Shutdown	Down
	gi0/1/0/13	unassigned	Shutdown	Down
	gi0/1/0/14	unassigned	Shutdown	Down
	gi0/1/0/15	unassigned	Shutdown	Down
	gi0/2/0/0	10.10.1.101	Up	Up
	gi0/2/0/1	10.1.1.1	Up	Up
	gi0/2/0/2	10.1.1.2	Up	Up
	gi0/2/0/3	unassigned	Shutdown	Down
	TenGigE0/3/0/0	unassigned	Shutdown	Down
	TenGigE0/3/0/2	unassigned	Shutdown	Down
	MgmtEth0/RSP0/CPU0/0	unassigned	Shutdown	Down

Step 8 Repeat these steps for every interface, until every interface shows both Status and Protocol as “Up.”
