IP Statistics

The following table describes the Internet Protocol statistics fields.

Table 13-8IP Statistics

Field	Description
ipInReceives	The total number of input datagrams received from interfaces, including those
	received in error.
ipInHdrErrors	The number of input datagrams discarded due to errors in their IP headers,
	including bad checksums, version number mismatch, other format errors,
	time-to-live exceeded, errors discovered in processing their IP options, and so
	forth.
ipInAddrErrors	The number of input datagrams discarded because the IP address in their IP
	header's destination field was not a valid address to be received at this entity (the
	switch). This count includes invalid addresses (for example, 0.0.0.0) and
	addresses of unsupported Classes (for example, Class E). For entities which are
	not IP Gateways and therefore do not forward datagrams, this counter includes
	datagrams discarded because the destination address was not a local address.
ipForwDatagrams	The number of input datagrams for which this entity (the switch) was not their
	final IP destination, as a result of which an attempt was made to find a route to
	forward them to that final destination. In entities which do not act as IP Gate-
	ways, this counter will include only those packets, which were Source-Routed
	via this entity (the switch), and the Source- Route option processing was success-
	ful.
ipInUnknownProtos	The number of locally addressed datagrams received successfully but discarded
	because of an unknown or unsupported protocol.
ipInDiscards	The number of input IP datagrams for which no problems were encountered to
	prevent their continued processing, but which were discarded (for example, for
	lack of buffer space). Note that this counter does not include any datagrams dis-
	carded while awaiting re-assembly.
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 (including
	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 data-
	grams counted in ipForwDatagrams if any such packets met this (discre-
	tionary) discard criterion.
