The operational mode command
domain information such as the designated port and the port roles. The spanning-tree
interface parameters for instance 2 show that both ports are designated ports, which
means Switch 2 is the root bridge for this instance.
The operational mode command
domain information at either the bridge level or interface level. If the optional interface
name is omitted, all interfaces in the spanning-tree domain are displayed.
Verifying MSTP Configuration on Switch 3
Verify the MSTP configuration on Switch 3.
Issue the operational mode commands show spanning-tree interface and show
spanning-tree bridge:
user@switch3> show spanning-tree interface
