The following table describes the IP statistics information displayed on the screen. 

Table 79.  IP routing 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, etc. 

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. 
This count includes invalid addresses (e.g., 0.0.0.0) and addresses of 
unsupported Classes (e.g., 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 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 Gateways, this 
counter includes only those packets which were Source-Routed via this entity, 
and the Source-Route option processing was successful. 

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 (e.g., for lack of 
buffer space). Note that this counter does not include any datagrams discarded 
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 (e.g., 
for lack of buffer space). Note that this counter would include datagrams 
counted in ipForwDatagrams if any such packets met this (discretionary) discard 
criterion. 

IpOutNoRoutes

The number of IP datagrams discarded because no route could be found to 
transmit them to their destination. Note that this counter includes any packets 
counted in ipForwDatagrams which meet this `no-route' criterion. Note that this 
includes any datagrams which a host cannot route because all of its default 
gateways are down.
