Usage Guidelines

Usage Scenario

After an Eth-Trunk in manual 1:1 master/backup mode is working properly, you can run the port-master command to specify a new master interface. Specifying a new master interface causes a short data interruption. To prevent the data interruption, you can run the protect-switch command in the view of the Eth-Trunk interface in manual 1:1 master/backup mode to manually switch the active and inactive interfaces. Each time the protect-switch command is run, the active and inactive interfaces are switched once.

Prerequisites

An Eth-Trunk interface in manual 1:1 master/backup mode has been created.

Example

# Manually switch the active and inactive interfaces in Eth-Trunk 1 that work in manual 1:1 master/backup mode.
