Table 5-7Interface Statistics for Port (/stats/port/if)

Statistics	Description
ifInOctets	The total number of octets received on the interface, including framing
	characters.
ifInUcastPkts	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.
ifInBroadcastPkts	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.
ifInMulticastPkts	The total number of packets that higher-level protocols requested to be
	transmitted, and which were addressed to a multicast address at this sub-
	layer, including those that were discarded or not sent. For a MAC layer
	protocol, this includes both Group and Functional addresses.
ifInDiscards	The number of inbound packets which were chosen to be 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.
ifInErrors	For packet-oriented interfaces, the number of inbound packets that con-
	tained errors preventing them from being delivered to a higher-layer pro-
	tocol. 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.
