Verify the Spanning Tree

For each RP and SCGE card in the system, verify that:

•One GE port in the Switched Interface column is in the forwarding (FWD) state.

•Each RP and SCGE card displays the same designated root MAC address.

•The designated root address matches the expected Catalyst switch, as defined by the Catalyst switch configuration. The root address should be the switch with the lowest priority number (0).

The following EXEC commands display RP and SCGE card information that you can use to verify the spanning tree:

RP/0/RP0/CPU0:router(admin)# show spantree mst 1 detail location 0/rp0/cpu0

Instance	1
Vlans mapped:	1
Designated Root	00-0e-39-fe-70-00
Designated Root Priority	1	(0 + 1)
Designated Root Port	GE_Port_0
