Viewing the MSTP configuration
Viewing the global MSTP configuration
This command displays the switch's basic and MST region spanning tree configuration, including
basic port connectivity settings.
Syntax:
show spanning-tree config
The upper part of this output shows the switch's global spanning tree configuration
that applies to the MST region. The port listing shows the spanning tree port
parameter settings for the spanning tree region operation configured by the
spanning-tree port-list command.
Syntax:
show spanning-tree port-list config
This command shows the same data as the above command, but lists the spanning
tree port parameter settings for only the specified port or trunk. 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 andtrk1, use the command: show spanning-tree a20-a24,trk1
