FDDI Ring State Descriptions
Ring State
Description
Isolated
The concentrator is not attached to the ring.
Non-Op
The concentrator 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
concentrator 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 concentrator and all stations between the concentrator
and its upstream neighbor will run self-tests.

Ring Connection Descriptions
Configuration
Description
Isolated
Both PHY-A and PHY-B are disconnected from the ring. There
are no connections at either the A or B FDDI port.
Wrap-A
PHY-A is wrapped via the MAC (from PHY-A/Primary In to MAC
to Secondary Out/PHY-A) and PHY-B is disconnected.
Wrap-B
PHY-B is wrapped via the MAC (from PHY-B/Secondary In to
MAC to Primary Out/PHY-B) and PHY-A is disconnected.
Wrap-AB
PHY-B is connected to the MAC (from PHY-B/Secondary In to
MAC to Primary Out/PHY-B) and PHY-A is wrapped (connecting
Primary In to Secondary Out), isolating PHY-A from the MAC.
