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
Discarded
The number of input datagrams for which no problems were
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.).
