Statistics 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, and so on.

ipInAddrErrors

The number of input datagrams discarded because the IP address in their IP

header destination field was not a valid address to be received at this switch.

This count includes invalid addresses (for example, 0.0.0.0) and addresses of

unsupported classes (for example, 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.

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 (for example, for

lack of buffer space).

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 that local IP user-protocols (including ICMP)

supplied to IP in requests for transmission.

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 (for

example, for lack of buffer space).

This counter would include datagrams counted in ipForwDatagrams if any

such packets met this (discretionary) discard criterion.

ipDefaultTTL

The default value inserted into the Time-To-Live (TTL) field of the IP header of

datagrams originated at this switch, whenever a TTL value is not supplied by

the transport layer protocol.
