Usage Guidelines

Usage Scenario

By default, the interface which is first added to an Eth-Trunk interface in manual 1:1 master mode or inter-board interface standby mode is the master interface. Only the master interface can forward traffic. To enable a backup interface to forward data, run either of the following commands:

Run the port-master command to specify the backup interface as the master interface.
Run the protect-switch command to manually switch the active and inactive interfaces.

Prerequisites

The following conditions are met:

The Eth-Trunk interface is configured to work in manual 1:1 master/backup mode using the mode command.
The Eth-Trunk member interfaces are physically Up.

Configuration Impact

This switching between active and inactive interfaces will cause a short data interruption.

Example

# Switch the backup interface of Eth-Trunk 1 as the active interface.

<sysname> system-view

[sysname] interface eth-trunk 1

[sysname-Eth-Trunk1] portswitch

[sysname-Eth-Trunk1] mode manual backup

[sysname-Eth-Trunk1] protect-switch
