Administering FDDI MACs 8-13
oldDownstream Previous value of the MAC address of this MAC’s downstream
neighbor
oldUpstream Previous value of the MAC address of this MAC’s upstream
neighbor
ringOpCount Number of times that this MAC has entered the operational state
from the nonoperational state
rmtState State of the ring management as defined in SMT
rxByteRate Average number of bytes received per second by this MAC during
the most recent sampling period
rxBytes Number of bytes received by this MAC, including framing
characters
rxDiscards Number of good frames received by this MAC and discarded
before being delivered to a higher-level protocol or application.
This count does not include frames that were not received into
receive buffers, such as missed frames.
rxFrameRate Average number of frames received per second by this MAC
during the most recent sampling period
rxFrames Number of frames received by this MAC
rxInternalErrs Number of frames discarded because of an internal hardware
error during reception
rxMulticasts Number of multicast frames delivered by this MAC to a
higher-level protocol or application
rxPeakByteRate Peak value of fddiMACByteReceiveRate for this MAC since the
station was last initialized
rxPeakFrameRate Peak value of fddiMACFrameReceiveRate for this MAC since the
station was last initialized
rxUnicasts Number of unicast (nonmulticast) frames delivered to a
higher-level protocol or application by this MAC
smtAddress Address of the MAC used for SMT frames
tMax Maximum value of the target token rotation time
tMaxCapab Maximum supported target token rotation time this MAC can
support
tNeg Target token rotation time negotiated during the claim process
tokenCount Number of tokens received by this MAC
tReq Target token rotation time requested by this MAC
