FDDI Management
Configuration
The Concentrator Configuration window, Figure6-2, 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
