Allied Telesis AT-9000/28 - Displaying STP Settings

AT-9000 Switch Command Line User’s Guide
Section VI: Spanning Tree Protocols 493
Displaying STP Settings
To view the STP settings on the switch, use the SHOW SPANNING-TREE
in the Privileged Exec mode. The command has this format:
show spanning-tree [interface port ]
Use the INTERFACE parameter to view the settings of the specified ports.
Otherwise, omit the parameter to view all the ports. Here is an example of
the information the command displays:
Figure 97. SHOW SPANNING-TREE Command
The one item this command does not display is which spanning tree
protocol, STP or RSTP, the switch is currently using. The words “Spanning
Tree” in the first line signal whether spanning tree is enabled or disabled,
not which spanning tree protocol is activated on the switch. For that, you
have to use the SHOW RUNNING-CONFIG command in the Privilege
Exec mode.
