Usage Guidelines STP is not supported on UNIs. Valid spanning-tree information is available only for NNIs or ENIs.
If the vlan-id variable is omitted, the command applies to the spanning-tree instance for all VLANs.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
