EKI-9500 Series User Manual 254
IpOutDiscards The number of output IP datagrams for which no problem was encoun-
tered to 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 which meet this no-
route criterion. Note that this includes any datagrams which a host
cannot route because all of its default gateways are down.
IpReasmTimeout The maximum number of seconds which received fragments are held
while they are awaiting reassembly at this entity.
IpReasmReqds The number of IP fragments received which needed to be reassem-
bled at this entity.
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 necessar-
ily a count of discarded IP fragments since some algorithms 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.
IpFragFails The number of IP datagrams that have been discarded because they
needed to be fragmented at this entity but could not be, e.g., 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.
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.
IcmpInMsgs The total number of ICMP messages which the entity received. Note
that this counter includes all those counted by icmpInErrors.
IcmpInErrors The number of ICMP messages which the entity received but deter-
mined as having ICMP-specific errors (bad ICMP checksums, bad
length, etc.).
IcmpInDestUn-
reachs The number of ICMP Destination Unreachable messages received.
IcmpInTimeExcds The number of ICMP Time Exceeded messages received.
IcmpInParmProbs The number of ICMP Parameter Problem messages received.
IcmpInSrcQuenchs The number of ICMP Source Quench messages received.
IcmpInRedirects The number of ICMP Redirect messages received.
IcmpInEchos The number of ICMP Echo (request) messages received.
IcmpInEchoReps The number of ICMP Echo Reply messages received.
IcmpInTimestamps The number of ICMP Timestamp (request) messages received.
IcmpInTimestam-
pReps The number of ICMP Timestamp Reply messages received.
IcmpInAddrMasks The number of ICMP Address Mask Request messages received.
IcmpInAd-
drMaskReps The number of ICMP Address Mask Reply messages received.
IcmpOutMsgs The total number of ICMP messages which this entity attempted to
send. Note that this counter includes all those counted by icmpOutEr-
rors.
