This value, ranging from 200 to 6000 centiseconds (2 to 60 seconds), sets the MRP LeaveAll timer for a port, which periodically forces all MRP participants to re-declare their registered VLANs or multicast groups, acting as a periodic cleanup mechanism to purge stale registrations. An administrator adjusts this when tuning how often the network performs this full re-registration cycle, balancing timely cleanup of stale entries against the burst of protocol traffic each LeaveAll cycle generates. With the default value of 1000 centiseconds (10 seconds), the switch triggers a LeaveAll re-registration cycle on this port roughly every ten seconds.
