USER’S GUIDE554 CyberSWITCHipOutRequestsThe total number of IP datagrams which local IP device-protocols (including ICMP) supplied to IPin requests for transmission.ipOutDiscardsThe number of output IP datagrams for which no problem was encountered that would preventtheir 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 packetsmet this (discretionary) discard criterion.ipOutNoRoutesThe number of IP datagrams discarded because no route could be found to transmit them to theirdestination. Note that this counter includes any packets counted in ipForwDatagrams that meetthis “no-route” criterion. Note that this includes any datagrams that a host cannot route because allof its default gateways are down.ipReasmTimeoutThe maximum number of seconds that received fragments are held while they are awaitingreassembly at this system.ipReasmReqdsThe number of IP fragments received which needed to be reassembled at this system.ipReasmOKsThe number of IP datagrams successfully reassembled.ipReasmFailsThe 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 somealgorithms (notably the algorithm in RFC 815) can lose track of the number of fragments bycombining them as they are received.ipFragOKsThe number of IP datagrams that have been successfully fragmented at this system.ipFragFailsThe number of IP datagrams that have been discarded because they needed to be fragmented atthis system but could not be, for example, because their “Don't Fragment” flag was set.ipFragCreatesThe number of IP datagram fragments that have been generated as a result of fragmentation at thissystem.ICMP GROUP STATISTICSicmpInMsgsThe total number of ICMP messages that the system received. Note that this counter includes allthose counted by icmpInErrors.icmpInErrorsThe number of ICMP messages that the system received but determined as having ICMP-specificerrors (bad ICMP checksums, bad length, etc.).
