ipInDelivers The total number of input datagrams successfully delivered to IP user-
protocols (including ICMP).
ipOutRequests The total number of IP datagrams which local IP user-protocols (includ-
ing ICMP) supplied to IP in requests for transmission. Note that this
counter does not include any datagrams counted in
ipForwDatagrams.
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.
ipOutNoRoutes 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, which meet this no-route crite-
rion. Note that this includes any datagrams which a host cannot route
because all of its default gateways are down.
ipReasmReqds The number of IP fragments received which needed to be reassembled at
this 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 nec-
essarily 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.
ipFragOKs The number of IP datagrams that have been successfully fragmented at
this entity (the switch).
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 Don't Fragment flag was set.
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.
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.
ipReasmTimeout The maximum number of seconds, which received fragments are held
while they are awaiting reassembly at this entity (the switch).
