accumulated. When the accumulated penalty exceeds the configured suppress threshold (2400), the interface state is set to Error-Disabled state. After the flap (flap 3), the interface flap stops. Then, the accumulated penalty decays exponentially and when it reaches below the set reuse threshold (300), the interface is unsuppressed and the interface state changes to "up" state. Enabling Link Dampening To enable link dampening, use the following command. • Enable link dampening. INTERFACE mode dampening Examples of the show interfaces dampening Commands To view the link dampening configuration on an interface, use the show config command.
