Secondary Indicates that the secondary FDDI ring is being used.
Primary Indicates that the primary FDDI ring is being used.
Concatenated Indicates the port is inserted in both the primary and secondary paths in a
concatenated wrap configuration.
Thru Indicates that the port is inserted in both the primary path and secondary
paths in a thru configuration.
Downstream Port Type The type of the first port that is downstream from this MAC (the exit port).
Possible types are A, B, S, M, or None.
T-Max Value The maximum supported value of Token Rotation Timer (TRT), displayed in
nanoseconds. T_Max is the length of time that an unsuccessful claim process
persists before a MAC on the ring begins to beacon.
TVX Value The Valid Transmission Timer (TVX) passed to the MAC, displayed in
nanoseconds. This is reset whenever a valid transmission is received. In the
event that TVX expires on a particular station, that station will start the
ring recovery process.
Frames Received The number of frames received by this MAC.
Frames Copied The number of frames addressed to and successfully copied into the station’s
receive buffers by this MAC. Note that this count does not include MAC
frames.
Frames Transmitted The number of frames transmitted by this MAC. Note that this count does
not include MAC frames.
Errors The number of frames that were detected in error by this MAC that had not
been detected in error by another MAC.
Format Errors The number of instances in which this MAC detected a format error during
frame reception such that the frame was stripped.
