Field
|
Description
|
InHdrErrors
|
The number of input data grams 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.
|
InAddrErrors
|
The number of input data grams discarded because the IP address in
their IP header's destination field was not a valid address to be received
at this entity. For entities which are not IP routers and therefore do not
forward datagrams, this counter includes datagrams discarded because
the destination address was not a local address.
|
InUnknownProtos
|
The number of locally-addressed datagrams received successfully but
discarded because of an unknown or unsupported protocol.
|
InDiscards
|
The number of input IP data grams 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.
|
OutDiscards
|
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
frames met this (discretionary) discard criterion.
|
OutNoRoutes
|
The number of IP datagrams discarded because no route could be found
to transmit them to their destination. Note that this counter includes any
frames 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 routers are down.
|
FragFails
|
The number of IP datagrams that have been discarded because they
needed to be fragmented at this entity but could not be, e.g., because
their Don't Fragment flag was set.
|
ReasmFails
|
The number of failures detected by the IP re-assembly algorithm (for
whatever reason: timed out, errors, etc). Note that this is not necessarily
a count of discarded IP fragments since some algorithms (notably the
algorithm in RFC 815) can lose track of the number of fragments by
combining them as they are received.
|
InReceives
|
The total number of input datagrams received from interfaces, including
those received in error.
|
InDelivers
|
The total number of input datagrams successfully delivered to IP
user-protocols (including ICMP).
|
OutRequests
|
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 data grams counted in
ipForwDatagrams.
|
ForwDatagrams
|
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 routers, this counter will include only those frames which were
Source-Routed via this entity, and the Source-Route option processing
was successful.
|
FragOKs
|
The number of IP datagrams that have been successfully fragmented at
this entity.
|
FragCreates
|
The number of IP datagram fragments that have been generated as a
result of fragmentation at this entity.
|
ReasmReqds
|
The number of IP fragments received which needed to be reassembled
at this entity.
|
ReasmOKs
|
The number of IP datagrams successfully re-assembled.
