The following example shows that the appropriate ports on Switch Port 1 are forwarding:
RP/0/RP0/CPU0:router# show controllers switch 1 ports location 0/RP1/CPU0
Ports Active on Switch 1
FE Port 1 STP State : FORWARDING (Connected to - 0/RP0)
FE Port 2 STP State : FORWARDING (Connected to - 0/RP1)
FE Port 9 STP State : FORWARDING (Connected to - 0/SM0)
GE Port 1 STP State : FORWARDING // connected to External switch through the front
panel
GE Port 2 STP State : FORWARDING // connected to the other Internal switch
The following example displays the spanning tree details including the designated root (expected MAC
address for the external Catalyst switch):
RP/0/RP0/CPU0:router# show spantree mst 1 brief location 0/rp1/cpu0
