link-group timer

Function

The link-group timer command sets an interface status monitoring timer for a link-group.

The undo link-group timer command restores the interface status monitoring timer for a link-group to the default value (10 seconds).

Format

Usage Guidelines

After a faulty interface in the link-group recovers, the system sets the state of other interfaces in the link-group to Up and checks whether all interfaces in the link-group are Up after twice of the interface status monitoring timer. If any interface is still Down, the system sets the state of other interfaces in the link-group to Down. Therefore, before configuring a link-group, check whether the delayed Up function is configured on the local interface to be added to the link-group and the peer interface. If yes, ensure that the interface status monitoring timer is longer than half of the interface Up delay to prevent frequent interface flapping, which interrupts services.

The default value of the interface status monitoring timer is 10 seconds.

Example

# Set the interface status monitoring timer to 5 seconds for link-group 1.
