Configuration

The Concentrator Configuration window, Figure 6-2, informs you about the configuration and operating state of the FDDI ring associated with the selected SMT entity, and displays parameters relating to ring initialization.

MAC State

This field indicates the current state of the selecting ring’s 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
