MP-Specific Information
These windows provide information about the switch’s internal processors:
ipOutNoRoutes
The number of IP datagrams discarded because no route could be found to trans-
mit them to their destination. Note that this counter includes any packets counted
in

in
ipForwDatagrams
, which meet this no-route criterion. Note that this
includes any datagrams which a host cannot route because all of its default gate-
ways are down.
ways are down.
ipReasmReqds
The number of IP fragments received which needed to be reassembled at this
entity (the switch).
entity (the switch).
ipReasmOKs
The number of IP datagrams successfully re- assembled.
ipReasmFails
The number of failures detected by the IP re- assembly algorithm (for whatever
reason: timed out, errors, and so forth). 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.

ipFragFails
The number of IP datagrams that have been discarded because they needed to be
fragmented at this entity (the switch) but could not be, for example, because their

ipFragCreates
The number of IP datagram fragments that have been generated as a result of
fragmentation at this entity (the switch).

ipRoutingDiscards
The number of routing entries, which 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.
