The following table describes IP statistics:
Table 46 IP Statistics
Statistic
Description
ipInReceives
The total number of input datagrams received from interfaces, including those received
in error.
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 (the 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.
ipInDelivers
The total number of input datagrams successfully delivered to IP userprotocols
(including ICMP).
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). Note that this counter would include datagrams counted in
ipForwDatagrams if any such packets met this (discretionary) discard criterion.
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 forth.
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). Note that this counter does not include any datagrams discarded while awaiting
re-assembly.
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.
ipDefaultTTL
The default value inserted into the Time-To-Live (TTL) field of the IP header of
datagrams originated at this entity (the switch), whenever a TTL value is not supplied by
the transport layer protocol.
