6.4 MSTP Troubleshooting 6.4.1 Monitoring And Debugging Command

6.4.1.1 show spanning-tree

Command: show spanning-tree [mst [<instance-id>]] [interface <interface-list>]

[detail]

Function: Display the MSTP Information.

Parameter: <instance-id> sets the instance ID. The valid range is from 0 to 48;

<interface-list> sets interface list; detail sets the detailed spanning-tree information.

Command mode: Privileged Mode

Usage Guide: This command can display the MSTP information of the instances in the

current bridge.

Example: Display the bridge MSTP.

Switch#sh spanning-tree

-- MSTP Bridge Config Info --

Standard : IEEE 802.1s

Bridge MAC : 00: 03: 0f: 01: 0e: 30
