MAC Configuration
The actual configuration of the station. Table 18 lists
the possible configurations and their descriptions.
Table 17: FDDI Ring States
Ring States 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 one 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 nine 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 can perform self-tests.

Description
Isolated The path is not inserted into any path.
Local_A The A port is inserted into a local path and
the B port is not.
Local_B The B port is inserted into a local path and
the A port is not.
Local_AB Both A and B are inserted into a local
path.
Local_S The S port is inserted into a local path.
Wrap_A The secondary path is wrapped to the A
port.
Wrap_B The secondary path is wrapped to the B
port.
Wrap_AB The primary path is wrapped to the B port
and the secondary path is wrapped to the
A port.
Wrap_S The primary port is wrapped to the S port.
C_Wrap_A The primary and secondary paths are
joined internally in the station and
wrapped to the A port. Regarding token
flow, all resources on the secondary path
precede those of the primary path.
