Chapter 3 Bringing Up the Cisco IOS XR Software on a Multishelf System

Verifying the Spanning Tree

	Command or Action	Purpose
Step 2
	show platform	Displays the status of all hardware components.
		• The state for all modules should be IOS XR RUN or
	Example:	OK.
	RP/0/RP0/CPU0:router(admin)# show platform	• It can take a few minutes for all LCC modules to start
		up.
		Note To view the status of all cards and modules, the
		show platform command must be executed in
		administration EXEC mode.
Step 3
	show spantree mst 1 detail location	Verifies the spanning tree.
	rack/slot/cpu0	• Enter this command for each RP and SCGE card in the
	Example:	system.
		• The output for each RP and SCGE card should display
	RP/0/RP0/CPU0:router(admin)# show spantree mst
		the following:
	1 detail location 0/rp0/cpu0
	RP/0/RP0/CPU0:router(admin)# show spantree mst	– In the Switched Interface column, one GE port
	1 detail location 0/rp1/cpu0
		should be in the forwarding (FWD) state.
	RP/0/RP0/CPU0:router(admin)# show spantree mst
	1 detail location 1/rp0/cpu0	– Each RP and SCGE card should display the same
	RP/0/RP0/CPU0:router(admin)# show spantree mst
		designated root MAC address.
	1 detail location 1/rp1/cpu0
	RP/0/RP0/CPU0:router(admin)# show spantree mst	• Verify that the designated root address matches the
	1 detail location F0/SC0/cpu0	expected Catalyst switch, as defined by the Catalyst
	RP/0/RP0/CPU0:router(admin)# show spantree mst
		switch configuration. The root address should be the
	1 detail location F0/SC1/cpu0
		switch with the lowest priority number (0).
		• For more information to configure and verify the
		external Catalyst switches, see the “Verifying the
		Catalyst Switch” section on page 3-18.

Examples

This section contains examples for the following subjects:

•Verify That the FCCs and Non-DSC LCC Are Communicating with the DSC, page 3-40

•Verify the Spanning Tree, page 3-41

Verify That the FCCs and Non-DSC LCC Are Communicating with the DSC

In the following EXEC mode example, all modules are displayed and the state for all modules is “IOS XR RUN.”

RP/0/RP0/CPU0:router# admin

RP/0/RP0/CPU0:router(admin)# show platform
