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.

 

Table 3-18 IP Statistics

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.
