■Statistics — The Ethernet and RMON statistics displayed for the

selected port are described in the following table.

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.
