FDDI Management
Configuration
The Concentrator Configuration window, Figure 5-2, 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 beacon process. This state
