Displaying Statistics for IP Protocols

IP Statistics

The Internet Protocol (IP) provides a mechanism for transmitting blocks of data (often called packets or frames) from a source to a destination, where these network devices (i.e., hosts) are identified by fixed length addresses. The Internet Protocol also provides for fragmentation and reassembly of long packets, if necessary, for transmission through “small packet” networks.

Statistical Values

Parameter	Description
Packets Received	The total number of input datagrams received from
	interfaces, including those received in error.
Received Address Errors	The number of input datagrams discarded because the IP
	address in the header's destination field was not a valid
	address for this entity.
Received Packets	The number of input datagrams for which no problems were
Discarded	encountered to prevent their continued processing, but which
	were discarded (e.g., for lack of buffer space).
Output Requests	The total number of datagrams which local IP user-protocols
	(including ICMP) supplied to IP in requests for transmission.
Output Packet No Route	The number of datagrams discarded because no route could
	be found to transmit them to their destination. Note that this
	includes any datagrams which a host cannot route because all
	of its default gateways are down.
Datagrams Forwarded	The number of input datagrams for which this entity 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.
Reassembly Required	The number of IP fragments received which needed to be
	reassembled at this entity.
Reassembly Failures	The number of failures detected by the IP re-assembly
	algorithm (for whatever reason: timed out, errors, etc.).
