CLI - This example provides detailed statistics on common IP-related protocols.

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.

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.
