display spantree Displays STP configuration and port-state information.
Syntax —

port-list — List of ports. If you do not specify any ports, MSS
displays STP information for all ports.
vlan vlan-id — VLAN name or number. If you do not specify a VLAN,
MSS displays STP information for all VLANs.
active — Displays information for only the active (forwarding) ports.
Defaults — None.

History — Introduced in MSS Version 3.0. Version 4.2 added a value STP

disabled on the port. The Disabled state is still used, but only to indicate
that the port is not forwarding traffic.
