secondary , isolated , concatenated , or thru
downstream MAC address of this MAC’s downstream neighbor
downstreamType PC type of this MAC’s downstream neighbor
dupAddrTest Pass or fail test for a duplicate address
duplicateAddr Whether this address is duplicated on the FDDI ring
errorCount Number of SMT MAC errors
frameCount Number of frames that this MAC received
frameErrCond Active when the frameErrorRatio is greater than or equal
to frameErrorThresh.
frameErrorRatio Ratio of the number lostCount plus the frameErrorCount
divided by the frameCount plus lostCount
frameErrThresh Threshold for determining when a MAC condition report
is generated
lateCount Number of token rotation timer expirations since this
MAC last received a token
llcAvailable Whether this MAC can send or receive LLC frames
llcService Setting of the Logical Link Control service
lostCount Number of frames and tokens that this MAC lost during
reception
noRxBuffers Number of frames discarded because no buffer space was
available
notCopiedCond Active when the notCopiedRatio is greater than or equal
to notCopiedThresh.
