Configuring IP Routing
IP Out Discards Number of output IP datagrams for which no
problem was encountered to prevent their
transmission to their destination, but were
discarded (for example, for lack of buffer space).
Note that this counter includes datagrams counted
in ipForwDatagrams if any such packets met this
(discretionary) discard criterion.
IP Out No Routes 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.
IP Reassembly Timeout
Period Maximum number of seconds that received
fragments are held while they are awaiting
reassembly at this entity.
IP Reassembly Required Number of IP fragments received that need to be
reassembled.
IP Reassembly OKs Number of IP datagrams successfully
reassembled.
IP Reassembly Failures Number of failures detected by the IP re-assembly
algorithm (timeout errors). Note that this is not
necessarily a count of discarded IP fragments
since some algorithms can lose track of the
number of fragments by combining them as they
are received.
IP Fragmentation OKs Number of IP datagrams that have been
successfully fragmented at this entity.
IP Fragmentation Failures Number of IP datagrams that have been discarded
because they needed to be fragmented at this
entity but could not be.
IP Fragmentation Creates Number of IP datagram fragments that have been
generated as a result of fragmentation at this
entity.
IP Routing Discards Number of routing entries that were chosen to be
discarded even though they are valid. One
possible reason for discarding such an entry could
be to free-up buffer space for other routing entries.
ICMP In Messages Total number of ICMP messages that the entity
received. Note that this counter includes all those
counted by icmpInErrors.
