Graphing switch chassis data 37
Field Description
OutDiscards The number of output IP datagrams for which
no problem was encountered to prevent their
transmission to their destination, but that 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.
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
packets counted in ipForwDatagrams that meet
this no-route criterion. Note that this includes any
datagrams a host cannot route because all of its
default gateways are down.
FragOKs The number of IP datagrams that have been
successfully fragmented at this entity.
FragFails The number of IP datagrams that have been discarded
because they needed to be fragmented at this entity
but could not be, for example, because their Don’t
Fragment flag was set.
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 that needed to
be reassembled at this entity.
ReasmOKs The number of IP datagrams successfully
reassembled.
ReasmFails The number of failures detected by the IP reassembly
algorithm (for whatever reason: timed out, errors,
and so on). Note that this is not necessarily a count
of discarded IP fragments because some algorithms
(notably the algorithm in RFC 815) can lose track of
the number of fragments by combining them as they
are received.
