The view contains the following information:
SMT Index
Displays the value of the SMT index associated with this MAC.
MAC Index
Provides an index variable for uniquely identifying the MAC object instances.
Token Count
Displays a count that should as closely as possible match the number of times
the station has received a token (total of non- restricted and restricted) on this
MAC. This count is valuable for determination of network load.
Tvx Expired Count
Displays a count that should as closely as possible match the number of times
that TVX has expired.
Late Count
Displays a count that should as closely as possible match the number of TRT
expirations since this MAC was reset or a token was received.
Ring Optional Count
Displays the count of the number of times the ring has entered the
“Ring_Operational” state from the “Ring_Not_Operational” state. This count
is updated when a change in the “Ring_Operational” status occurs. Because of
implementation considerations, this count may be less than the actual
“RingOp_Ct”. It is not a requirement that this count be exact.
Frame Count
Displays a count of the number of frames received by this MAC.
Transmit Count
Displays a count that should as closely as possible match the number of
frames transmitted by this MAC. This count does not include MAC frames.
Error Count
Displays a count of the number of frames that were detected in error by this
MAC that had not been detected in error by another MAC.
Lost Count
Displays a count of the number of instances that this MAC detected a format
error during frame reception such that the frame was stripped.
Frames Copied
Indicates the number of frames addressed to this MAC and which were copied
into its receiving buffers.
Frames Not Copied
Displays a count that should as closely as possible match the number of
frames that were addressed to this MAC but were not copied into its receive
buffers. For example, this might occur due to local buffer congestion. Because
of implementation considerations, this count may not match the actual
number of frames not copied. It is not a requirement that this count be exact.
This count does not include MAC frames.
