InDiscards
Total valid frames received that are discarded due to lack of
buffer space. This includes frames discarded at ingress as well as
those dropped due to priority and congestion considerations at
the output queues. Frames dropped at egress due to excessive
collisions are not included but are counted in the Excessive
counter.
InFiltered
If 802.1Q is disabled on the port, these are the total valid frames
received that are not forwarded to a destination port. These are
frames for which the destination
port vector is 0 or are not
forwarded due to the state of the portState bits. valid frames
discarded due to a lack of buffer space are not included.
If 802.1Q is enabled on the port, then these are the total valid
frames received (tagged or untagged) that were discarded due
to an unknown VID (i.e., the frame's VID was not in the VTU)
OutUnicasts
Total valid
frames transmitted with a unicast destination
address
OutBroadcasts
Total valid frames transmitted with destination address equal to
FF:FF:FF:FF:FF:FF.
OutPause
Total pause frames transmitted.
OutMulticasts
Total valid frames transmitted
with multicast destination
address that are not counted in OutBroadcasts or OutPause.
OutFCSErr
Total frames transmitted with a valid length and an invalid FCS.
OutGoodOctets
Total data octets transmitted. The count includes the FCS but
not the preamble.
Out64Octets
Total frames transmitted with a length
of exactly 64 octets,
including
those with errors.
Out127Octets
Total frames transmitted with a length
of between 65 and 127
octets inclusive, including those with errors.
Out255Octets
Total frames transmitted with a length
of between 128 and
255 octets inclusive, including those with errors.
Out511Octets
Total frames transmitted with a length
of between 256 and
511 octets inclusive, including those with errors.
Out1023Octets
Total frames transmitted with a length
of between 512 and
1023 octets inclusive, including those with errors.
OutMaxOctets
Total frames transmitted with a length of between 1024 and
1522 octets inclusive, including those with errors.
Collisions
Total number of collisions during frame transmission.
Late
Total number of times collision is detected later than 512 bit-
times into the transmission of a frame.
Excessive
Total number of frames not transmitted because the frame
experienced 16 transmission attempts and was discarded. The
discard will only occur if DiscardExcessive is set to a 1 (in global
control register).
Multiple
Total number of successfully transmitted frames that
experienced more than on collision.
