MAC State

This Þeld indicates the current state of the selecting ringÕs MAC component. (The RMT component of SMT monitors MAC operation and takes actions necessary to aid in achieving an operational ring.) Possible states are:

Not Available	There is no MAC on the FDDI ring associated with the
	SMT entity.
Ring-Op	The ring is functioning normally. While in this state, the
	MAC being managed is part of an operational FDDI ring.
Isolated	SMT has just initialized RMT or RMT has entered this
	state during a path test (trace) after ring beaconing; RMT
	is not aware of the ring path or state.
Non-Op	The MAC being managed by the selected SMT is
	participating in ring recovery; the ring is not operational.
Detect	The claim (beacon) process of the FDDI ring protocol has
	exceeded one second. There may be a problem on the
	ring; any duplicate address conditions are being
	detected. In this state, the ring is still alive, but no data is
	being transmitted.
Non-Op-Dup	The ring is not operational; the address of the MAC
	under control of the SMT entity has been found to
	duplicate that of another MAC on the ring. The duplicate
	address condition prevented ring recovery and
	initialization after a claim and beacon process. This state
	will not occur unless you are using locally- administered
	addresses, as factory-set MAC addresses are guaranteed
	to be unique.
Ring-Op-Dup	The ring is operational; however, the address of the MAC
	under control of the SMT entity has been found to
	duplicate that of another MAC on the ring. Corrective
	actions will be attempted before the duplicate address
