This command displays the switch's global and regional
spanning-tree status, plus the per-port spanning-tree
operation at the regional level. Note that values for the
following parameters appear only for ports connected to active
devices: Designated Bridge, Hello Time, PtP, and Edge.
This command displays the spanning-tree status for the
designated port(s). You can list data for a series of ports and
port trunks by specifying the first and last port or trunk of any
consecutive series of ports and trunks. For example, to display
data for port A20-A24 and trk1, you would use this command:
show spanning-tree a20-trk1
