Displaying STP Bridge and Port Information

To display STP bridge and port information, use the following command:

show spantree [port-listvlan vlan-id] [active]

By default, STP information for all ports and all VLANs is displayed. To display STP information for specific ports or a specific VLAN only, enter a port list or a VLAN name or number. For each VLAN, only the ports contained in the VLAN are listed in the command output.

To list only the ports that are in the active (forwarding) state, enter the active option.

To display STP information for VLAN mauve, type the following command:

23x0# show spantree vlan mauve
