Description: This table lists any locked MAC address for each port along with their entry types. On each port in the system, MACs can be locked. For each MAC locked to a port, a row appears in this table.

When MAC locking is enabled on a port, the first n packets received by the port has its source MAC locked to the port and the locked cause displays firstArrival(2) The value n is equal to the etsysMACLockingFirstArrivalStationsAllocated object.

Additionally, management may explicitly lock a MAC to a port by using the etsysMACLockingStationStaticTable. For each entry in the static table that is active(1), a corresponding entry appears in this table with its etsysMACLockingLockedEntryCause object set to static(1).
