Parameter
enable-threshold: Percentage of the available bandwidth that the traffic load must
exceed to bring up a standby interface or logical channel. It is in the range 2 to 99.
disable-threshold: Percentage of the available bandwidth that the traffic load must be
less than to close a standby interface or logical channel. It is in the range 1 to 99.
Description
Use the standby threshold command to configure backup load sharing on an
interface or logical channel.
Use the undo standby threshold command to disable backup load sharing on the
interface or logical channel.
By default, backup load sharing is disabled.
This command applies to the main interface in the backup center. When the traffic on all
the active interfaces reaches the enable-threshold, the backup center enables the
standby interface with the highest priority. When the total traffic on all active interfaces
decreases below the disable-threshold, the backup center disables the standby
interface with the lowest priority.
The enable-threshold argument must not be less than the disable-threshold argument.
Executing the undo standby threshold command shuts down all standby interfaces
that have been enabled, if there is any. After that, only the main interface works.
Related command: standby interface.
