the main interface, you cannot configure the standby track command on both the main interface and its backup interface; if you have associated an interface with a Track object, you cannot configure the interface as the main interface or a backup interface.

Related commands: standby track.

Example # Specify interface Serial 2/1 to back up interface Serial 2/0, and assign it the priority of 50.

Parameter enable-threshold: Specifies upper value of the load sharing threshold. It indicates the percentage of the available main-interface bandwidth that the traffic load must exceed for the backup interface to come up for load sharing. It ranges from 1 to 99.

disable-threshold: Specifies lower value of the load sharing threshold. It indicates the percentage of the available main-interface bandwidth that the traffic load must be less than for the backup interface in load sharing to shut down. It ranges from 1 to 99. The disable-threshold must be smaller than the enable-threshold.

Description Use the standby threshold command to configure load sharing thresholds.

Use the undo standby threshold command to remove the configuration.

By default, load sharing threshold is disabled.

The following is how backup/load sharing works:

■When the traffic on the main interface increases above the enable-threshold, the backup center brings up the highest-priority backup interface, and then other backup interfaces in decreasing priority order depending on traffic size.

■When the traffic on the main interface decreases below the disable-threshold, the backup center shuts down the lowest-priority backup interface first and then other participant backup interfaces in increasing priority order depending on traffic size.
