Physical interface event damping

Interface damping is supported on physical interfaces to address longer periodic flapping lasting 5 seconds or more, with an up and down duration of 1 second. This damping method limits the number of advertisements of longer interface up and down events to the upper-level protocols. For longer periodic interface flaps, configure interface damping with the damping statement at the [edit interfaces interface-name] hierarchy level. You use the show interfaces extensive command to view the interface damping values and link state.
