sys_IpInDiscards The number of input IP packets for which no problems were encountered to
prevent their continued processing, but which were discarded (e.g., for lack of
buffer space). Note that this counter does not include any IP packets discarded
while awaiting re-assembly.
sys_IpInDelivers The total number of input IP packets successfully delivered to IP user-protocols
(including ICMP).
sys_IpOutRequests The total number of IP packets which local IP user-protocols (including ICMP)
supplied to IP in requests for transmission. Note that this counter does not
include any IP packets counted in ipForwDatagrams.
sys_IpOutDiscards The number of output IP packets for which no problem was encountered to
prevent their transmission to their destination, but which were discarded (e.g.,
for lack of buffer space). Note that this counter would include IP packets
counted in ipForwDatagrams if any such packets met this (discretionary) discard
criterion.
sys_IpOutNoRoutes The number of IP packets 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.
sys_IpReasmTimeout The maximum number of seconds which received fragments are held while they
are awaiting reassembly at this entity.
sys_IpReasmReqds The number of IP fragments received which needed to be reassembled at this
entity.
sys_IpReasmOKs The number of IP packets successfully re-assembled.
sys_IpReasmFails The number of failures detected by the IP re-assembly 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.
sys_IpFragOKs The number of IP packets that have been successfully fragmented at this entity.
sys_IpFragFails The number of IP packets 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.
sys_IpFragCreates The number of IP packet fragments that have been generated as a result of
fragmentation at this entity.
sys_IcmpInMsgs The total number of ICMP messages which the entity received. Note that this
counter includes all those counted by icmpInErrors.
sys_IcmpInErrors The number of ICMP messages which the entity received but determined as
having ICMP-specific errors (bad ICMP checksums, bad length, etc.).
sys_IcmpInDestUnreachs The number of ICMP Destination Unreachable messages received.
sys_IcmpInTimeExcds The number of ICMP Time Exceeded messages received.
sys_IcmpInParmProbs The number of ICMP Parameter Problem messages received.
sys_IcmpInSrcQuenchs The number of ICMP Source Quench messages received.
sys_IcmpInRedirects The number of ICMP Redirect messages received.
sys_IcmpInEchos The number of ICMP Echo (request) messages received.
sys_IcmpInEchoReps The number of ICMP Echo Reply messages received.
sys_IcmpInTimestamps he number of ICMP Timestamp (request) messages received.
sys_IcmpInTimestampReps The number of ICMP Timestamp Reply messages received.
sys_IcmpInAddrMasks The number of ICMP Address Mask Request messages received.
