Table 5-14IP Statistics (stats/l3/ip)

Statistics	Description
ipInDelivers	The total number of input datagrams successfully delivered to IP user-
	protocols (including ICMP).
ipOutRequests	The total number of IP datagrams which local IP user-protocols (includ-
	ing ICMP) supplied to IP in requests for transmission. Note that this
	counter does not include any datagrams counted in
	ipForwDatagrams.
ipOutDiscards	The number of output IP datagrams for which no problem was
	encountered to prevent their transmission to their destination, but which
	were discarded (for example, for lack of buffer space). Note that this
	counter would include datagrams counted in ipForwDatagrams if any
	such packets met this (discretionary) discard criterion.
ipOutNoRoutes	The number of IP datagrams discarded because no route could be found
	to transmit them to their destination. Note that this counter includes any
	packets counted in ipForwDatagrams, which meet this no-routecrite-
	rion. Note that this includes any datagrams which a host cannot route
	because all of its default gateways are down.
ipReasmReqds	The number of IP fragments received which needed to be reassembled at
	this entity (the switch).
ipReasmOKs	The number of IP datagrams successfully re- assembled.
ipReasmFails	The number of failures detected by the IP re- assembly algorithm (for
	whatever reason: timed out, errors, and so forth). Note that this is not nec-
	essarily a count of discarded IP fragments since some algorithms (notably
	the algorithm in RFC 815) can lose track of the number of fragments by
	combining them as they are received.
ipFragOKs	The number of IP datagrams that have been successfully fragmented at
	this entity (the switch).
ipFragFails	The number of IP datagrams that have been discarded because they
	needed to be fragmented at this entity (the switch) but could not be, for
	example, because their Don't Fragment flag was set.
ipFragCreates	The number of IP datagram fragments that have been generated as a
	result of fragmentation at this entity (the switch).
ipRoutingDiscards	The number of routing entries, which were chosen to be discarded even
	though they are valid. One possible reason for discarding such an entry
	could be to free-up buffer space for other routing entries.
ipDefaultTTL	The default value inserted into the Time-To-Live(TTL) field of the
	IP header of datagrams originated at this entity (the switch), whenever a
	TTL value is not supplied by the transport layer protocol.
