Through-A Indicates that the primary ring is connected to the
MAC (from PHY-A/Primary In to MAC to Primary Out/
PHY-B). The secondary ring is isolated from the MAC
(from PHY-B/Secondary In to PHY-A/Secondary Out).
Through-B Indicates that the secondary ring is connected to the
MAC (from PHY-B/Secondary In to MAC to Secondary
Out/PHY-A). The primary ring is isolated from the
MAC (from PHY-A/Primary In to PHY-B/Primary Out).

State Description
Isolated The EFDMIM is not attached to the ring.
Non-Op The EFDMIM is attempting to enter the ring.
Ring-Op The ring is operational.
Detect The claim/beacon process of the FDDI ring protocol has
exceeded 1 second. This indicates a potential problem.
Non-Op-Dup The ring failed to complete the claim/beacon process
because a duplicate FDDI address has been detected.
Ring-Op-Dup The ring is operational but a duplicate FDDI address
has been detected.
Directed The claim/beacon process did not complete within 9
seconds. The EFDMIM is now sending directed
beacons to indicate a problem.
Trace A problem has been detected with the station or its
upstream neighbor. A trace is being sent to notify the
upstream neighbor of the problem. The EFDMIM and
all stations between the EFDMIM and its upstream
neighbor will run self-tests.
