ROUTELESS DISCARDS

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 TOTAL FORWARDED DATAGRAMS which meet this “no-route” criterion. Note also that this includes any datagrams which a host cannot route because all of its default gateways are down.

IP REASSEMBLY TIMEOUT

The maximum number of seconds received fragments are held while awaiting reassembly at this unit.

DISASSEMBLED FRAGMENTS

The number of IP fragments received which needed to be reassembled at this unit.

IP DATAGRAMS REASSEMBLED

The number of IP datagrams successfully reassembled.

IP REASSEMBLY FAILURES

The number of failures detected by the IP reassembly algorithm (for whatever reason: timed out, errors, etc.). Note that this is not necessarily a count of discarded IP fragments since some algorithms (notably RFC 815s) can lose track of the number of fragments by combining them as they are received.

SUCCESSFUL FRAGMENTS

The number of IP datagrams that have been successfully fragmented at this unit.

FAILED FRAGMENTS

The number of IP datagrams that have been discarded because they needed to be fragmented at this unit but could not be e.g., because their “Don't Fragment” flag was set.

TOTAL IP FRAGMENTS

The number of IP datagram fragments that have been generated as a result of fragmentation at this unit.

DISCARDED ROUTING ENTRIES

A packet the unit couldn't route.

CLEAR COUNTS

Setting this activator clears the IP Statistics.
