The mac-move command enables the feature at the service level for SAPs and spoke SDPs, as only
those objects can be blocked by this feature. Mesh SDPs are never blocked, but their re-learn rates
(sap-to-mesh/spoke-to-mesh or vice versa) are still measured.
The operation of this feature is the same on the SAP and spoke SDP. For example, if a MAC address
moves from SAP to SAP, from SAP to spoke SDP, or between spoke SDPs, one will be blocked to
prevent thrashing. If the MAC address moves between a SAP and mesh SDP or spoke SDP and mesh
SDP combinations, the respective SAP or spoke SDP will be blocked.
The re-learn rate is computed as the number of times a MAC moves in a 5 second interval. Therefore,
the fastest a loop can be detected and broken is 5 seconds.
The no form of this command disables MAC move.
Default not enabled
