Routing
218
M4100 Series Managed Switch
IpInDiscards The number of input IP datagrams for which no problems were
encountered to prevent their continued processing, but that were
discarded (such as for lack of buffer space). Note that this counter does
not include any datagrams discarded while awaiting reassembly.
IpInDelivers The total number of input datagrams successfully delivered to IP user
protocols (including ICMP).
IpOutRequests The total number of IP datagrams that local IP user protocols (including
ICMP) supplied to IP in requests for transmission.This counter does not
include any datagrams counted in ipForwDatagrams.
IpOutDiscards The number of output IP datagrams for which no problem was
encountered to prevent their transmission to their destination, but that
were discarded (such as 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 entity.
IpReasmReqds The number of IP fragments received that needed to be reassembled at
this entity.
IpReasmOKs The number of IP datagrams successfully re-assembled.
IpReasmFails The number of failures detected by the IP re-assembly algorithm (for
whatever reason: timed out, errors, and so on). This is not necessarily
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 were successfully fragmented at this
entity.
IpFragFails The number of IP datagrams that were discarded because they needed
to be fragmented at this entity but could not be, such as because their
Don't Fragment flag was set.
IpFragCreates The number of IP datagram fragments that were generated as a result
of fragmentation at this entity.
IpRoutingDiscards The number of routing entries that were 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 that the entity received. Note that
this counter includes all those counted by icmpInErrors.
