selected port are described in the following table.
Tab le 12 Port Statistics Summary Page - Field Description
Field Description
Octets Input The total number of octets received on the interface,
including framing characters.
Octets Output The total number of octets transmitted out of the
interface, including framing characters.
Unicast Input The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were not addressed to a
multicast or broadcast address at this sub-layer.
Unicast Output The total number of packets that higher-level protocols
requested be transmitted, and which were not
addressed to a multicast or broadcast address at this
sub-layer, including those that were discarded or not
sent.
Discard Output The number of outbound packets which were chosen to
be discarded even though no errors had been detected
to prevent their being transmitted. One possible reason
for discarding such a packet could be to free up buffer
space.
Error Input For packet-oriented interfaces, the number of inbound
packets that contained errors preventing them from
being deliverable to a higher-layer protocol. For
character- oriented or fixed-length interfaces, the
number of inbound transmission units that contained
errors preventing them from being deliverable to a
higher-layer protocol.
Error Output For packet-oriented interfaces, the number of outbound
packets that could not be transmitted because of errors.
For character-oriented or fixed-length interfaces, the
number of outbound transmission units that could not
be transmitted because of errors
QLen Output The length of the output packet queue (in packets).
Multicast Input The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast
address at this sub-layer.
Multicast Output The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to
a multicast address at this sub-layer, including those that
were discarded or not sent.
Broadcast Input The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a broadcast
address at this sub-layer.
