tReq Target token rotation time that this MAC requested
tvxCapab Maximum time value of the valid transmission timer that
this MAC can support
tvxExpiredCount Number of times that this MAC’s valid transmission timer
has expired
tvxValue Value of the valid transmission timer that this MAC uses
txByteRate Average number of bytes that this MAC transmitted per
second during the most recent sampling period
txBytes Number of bytes that this MAC transmitted
txDiscards Number of frames discarded because LLC service was not
enabled or the FDDI ring was not operational
txFrameRate Average number of frames that this MAC transmitted per
second during the most recent sampling period
txFrames Number of frames that this MAC transmitted. This
number does not include MAC frames.
txInternalErrs Number of frames discarded because of an internal
hardware error during transmission
txMulticasts Number of multicast frames queued for transmission by a
higher-level protocol or application, including frames not
transmitted successfully
txPeakByteRate Peak value of fddiMACByteTransmitRate for this MAC
since the station was last initialized
txPeakFrameRate Peak value of fddiMACFrameTransmitRate for this MAC
since the station was last initialized
txQOverflows Number of frames discarded because the transmit queue
was full
txUnicasts Number of unicast frames queued for transmission by a
higher-level protocol or application, including frames not
transmitted successfully
upstream MAC address of this MAC’s upstream neighbor
upstreamDupAddr Whether the address upstream of this address is
duplicated on the ring
