Interface backup configuration task list

Configuring strict active/standby interface backup:

• (Method 1.) Explicitly specifying backup interfaces without traffic thresholds

• (Method 2.) Using interface backup with the Track module

You cannot use these two methods at the same time for a primary interface and its backup interfaces.

Use method 1 if you want to monitor the interface state of the primary interface for a switchover to occur.

Use method 2 if you want to monitor any other state, such as the link state of the primary interface.

Configuring load-shared interface backup

A primary interface and its backup interfaces operate in load sharing mode after you specify the traffic thresholds on the primary interface.

This method cannot be used with the other two methods at the same time for an interface.
