Verifying the MSTP Protection Function Configuration

Verifying the MSTP Protection Function Configuration

After Multiple Spanning Tree Protocol (MSTP) protection functions are configured, verify the configuration.

Prerequisites

All configurations of MSTP protection functions are complete.

Procedure

  • Run the display stp [ instance instance-id ] [ interface { interface-type interface-number } ] [ brief ] command to view spanning-tree status and statistics.

Example

Run the display stp command, and you can view the Bridge Protocol Data Unit (BPDU) protection status and configured protection type on a switching device. For example:

<HUAWEI> display stp instance 0 interface gigabitethernet 0/1/0
