Enterasys Networks CSX7000, CSX5500, CSX6000 manual Number of IP datagrams successfully reassembled

USER’S GUIDE

ipInUnknownProtos

The number of locally addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.

ipInDiscards

The number of input IP datagrams for which no problems were encountered that would prevent their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly.

ipInDelivers

The total number of input datagrams successfully delivered to IP device-protocols (including ICMP).

ipOutRequests

The total number of IP datagrams which local IP device-protocols (including ICMP) supplied to IP in requests for transmission.

ipOutDiscards

The number of output IP datagrams for which no problem was encountered that would prevent their transmission to their destination, but which were discarded (e.g., 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 that meet this “no-route” criterion. Note that this includes any datagrams that a host cannot route because all of its default gateways are down.

ipReasmTimeout

The maximum number of seconds that received fragments are held while they are awaiting reassembly at this system.

ipReasmReqds

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

ipReasmOKs

The number of IP datagrams successfully reassembled.

ipReasmFails

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 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 system.

ipFragFails

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