Description
The number of packets received by a port that have a length
(excluding framing bits but including FCS) between 64 and 1522
bytes inclusive, and have a bad FCS with an integral number of
bytes.
The total number of bytes in all good packets received by a port
(excluding framing bits, but including FCS).
The number of good packets received by a port that were
dropped due to lack of resources or were dropped due to a lack
of resources before a determination of the validity of the packet
was able to be made. This counter is only incremented if the
receive error was not counted by either the
RX_EXCESS_SIZE_DISC, the RX_ALIGNMENT_ERRORS, or
the RX_FCS_ERRORS counters.
The number of good packets received by a port that are
addressed to a unicast address.
The number of good packets received by a port that are directed
to a multicast address. This counter does not include errorred
multicast packets or valid broadcast packets.
The number of good packets received by a port that are directed
to a broadcast address. This counter does not include errored
broadcast packets or valid multicast packets.
The number of times the SA of good receive packets has
changed from the previous value. A count greater than 1
generally indicates the port is connected to a repeater based
network.
The number of packets received by a port that are less than 64
bytes (excluding framing bits) and have either an FCS error or
an alignment error.
The number of good packets received by a port that are greater
than 1536 bytes (excluding framing bits, but including the FCS)
and were discarded due to excessive length. Note the
RX_OVERSIZE_PKTS counter alone is incremented for packets
in the range 1523-1536 bytes inclusive; whereas, both this
counter and the RX_OVERSIZE_PKTS counter are
incremented for packets of 1537 bytes and higher.
