Table 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.
