CONFIGURING THE SWITCH

Table 3-11 Port Statistics (Continued)

Parameter	Description

Received Discarded	The number of inbound packets which were chosen
Packets	to be discarded even though no errors had been
	detected to prevent their being deliverable to a
	higher-layer protocol. One possible reason for
	discarding such a packet could be to free up buffer
	space.

Received Unknown	The number of packets received via the interface
Packets	which were discarded because of an unknown or
	unsupported protocol.

Received Errors	The number of inbound packets that contained errors
	preventing them from being deliverable to a
	higher-layer protocol.

Transmit Octets	The total number of octets transmitted out of the
	interface, including framing characters.

Transmit Unicast Packets	The total number of packets that higher-level
	protocols requested be transmitted to a
	subnetwork-unicast address, including those that were
	discarded or not sent.

Transmit Multicast Packets	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.

Transmit Broadcast	The total number of packets that higher-level
Packets	protocols requested be transmitted, and which were
	addressed to a broadcast address at this sub-layer,
	including those that were discarded or not sent.

Transmit Discarded	The number of outbound packets which were chosen
Packets	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.

Transmit Errors	The number of outbound packets that could not be
	transmitted because of errors.
