7.6.3.5 Checking the Configuration. Huawei AR550 Series, AR530 Series

Huawei AR530&AR550 Series Industrial Switch Routers

Configuration Guide - Ethernet Switching 7 MSTP Configuration

NOTE

An alternate port is a backup port for a root port. If a switching device has an alternate port, you need to configure loop protection on both the root port and the alternate port.

Perform the following steps on the root port and alternate port on a switching device in an MST region.

Procedure

Step 1 Run: system-view

The system view is displayed.

Step 2 Run: interface interface-type interface-number

The Ethernet interface view is displayed.

Step 3 Run: stp loop-protection

Loop protection for the root port is configured on the switching device.

By default, loop protection is disabled.

Root protection and loop protection cannot be configured simultaneously.
