Displaying Information About Ports
Octets – The number of received and transmitted bytes (good and
■
bad), including Frame Check Sequence, but excluding framing bits.
Unicast – The number of received and transmitted unicast packets
■
(good and bad).
Multicast – The number of received and transmitted multicast
■
packets (good and bad).
Broadcast – The number of received and transmitted broadcast
■
packets (good and bad).
Pause – A count of the MAC Control frames received or transmitted
■
on this port that have an opcode indicating a PAUSE operation.
Receive/Transmit Size Counters – The number of received and
◆
transmitted packets (good and bad) split into categories based on their
respective frame sizes.
Receive/Transmit Queue Counters – The number of received and
◆
transmitted packets per input and output queue.
Receive Error Counters
◆
Rx Drops – The number of inbound packets which were discarded
■
even though no errors had been detected to prevent their being
delivered to a higher-layer protocol. One possible reason for
discarding such a packet could be to free up buffer space.
Rx CRC/Alignment – The number of frames received with CRC or
■
alignment errors.
Rx Undersize – The total number of frames received that were less
■
than 64 octets long (excluding framing bits, but including FCS
octets) and were otherwise well formed.
Rx Oversize – The total number of frames received that were
■
longer than the configured maximum frame length for this port
(excluding framing bits, but including FCS octets) and were
otherwise well formed.
Rx Fragments – The total number of frames received that were
■
less than 64 octets in length (excluding framing bits, but including
FCS octets) and had either an FCS or alignment error.
Rx Jabber – The total number of frames received that were longer
■
than the configured maximum frame length for this port (excluding
framing bits, but including FCS octets), and had either an FCS or
alignment error.
Rx Filtered – The number of received frames filtered by the
■
forwarding process.
Transmit Error Counters
◆
Tx Drops – The number of frames dropped due to output buffer
■
congestion.
Tx Late/Exc. Coll. – The number of frames dropped due to late or
■
excessive collisions.
