MAC Configuration
The actual configuration of the station. Table 17 lists
the possible configurations and their descriptions.
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 can perform self-tests.

Ring States 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.
Table 16: FDDI Ring States (Continued)
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.
C_Wrap_B The primary and secondary paths are joined
internally in the station and wrapped to the B
port. Regarding token flow, all resources on
the secondary path precede those of the
primary path.
C_Wrap_S The primary and secondary paths are joined
internally in the station and wrapped to the S
port. Regarding token flow, all resources on
the secondary path precede those of the
primary path.
Thru The primary path enters the A port and
emerges from the B port. The secondary path
enters the B port and emerges from the A
port.
