STP Maintenance Configuration

Introduction

In a large-scale network with MSTP enabled, there may be many MSTP instances, and so the status of a port may change frequently. In this case, maintenance personnel may expect that log/trap information is output to the log host when particular ports fail, so that they can check the status changes of those ports through alarm information.

Enabling Log/Trap Output for Ports of MSTP Instance

Follow these steps to enable log/trap output for ports of MSTP instance:

To do…	Use the command…	Remarks
Enter system view	system-view	—
		Required
Enable log/trap output for the	stp [ instance instance-id]	By default, log/trap output is
