128 – 255 Total frames received with a length of between 128 and 255 octets

inclusive, including those with errors.

256 – 511 Total frames received with a length of between 256 and 511 octets

inclusive, including those with errors.

512 – 1023 Total frames received with a length of between 512 and 1023 octets

inclusive, including those with errors.

1024 - 1522 Total frames received with a length of between 1024 and 1522

octets inclusive, including those with errors. The maximum packet

size is 1518 for non-tagged frames, 1522 for tagged frames.

Octets Total data octets received in frames with a valid FCS. Undersize and

Oversize frames are included. The count includes the FCS but not the

preamble.

Pkts The number of packets.

UnicastPkts Total valid frames received with a unicast Destination Address.

BroadcastPkts Total valid frames received with a Destination Address equal to

FF:FF:FF:FF:FF:FF.

PauseFrames Total valid pause frames received.

MulticastPkts Total valid frames received with a multicast Destination Address that

are not counted in BroadcastPkts or PauseFrms.

Discards Total valid frames received that are discarded due to a 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.

AlignmentErros Total frames received with a valid length (between 64 octets and

MaxPktSz octets inclusive) that have an invalid FCS and a non-

integral number of octets.

BadOctets Total data octets received in frames with an invalid FCS. Fragments

and Jabbers are included. The count includes the FCS but not the

preamble.

UndersizePkts Total frames received with a length of less than 64 octets but with a

valid FCS.

Fragments Total frames received with a length of less than 64 octets and an

invalid FCS.

Jabber Total frames received with a length of more than MaxPktSz octets

but with an invalid FCS.

OversizePkts Total frames received with a length of more than MaxPktSz octets

but with a valid FCS.

Filtered If Ingress Filtering is disabled on this port: 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 Ingress Filtering is enabled on this port: 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).

Transmit

Counters for traffic transmitted.
