52 Chapter 3 Configuring network monitoring using Device Manager
Field Description
ForwDatagrams The number of input datagrams for which this entity
was not their final IP destination, as a result of which
an attempt was made to find a route to forward them to
that final destination. For addresses that do not act as
IP Gateways, this counter includes only those packets
that are Source-Routed by way of this address and
have successful Source-Route option processing.
InUnknownProtos The number of locally addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol.
InDiscards The number of input IP datagrams for which no
problems were encountered to prevent their continued
processing but that were discarded (for example, for
lack of buffer space). Note that this counter does
not include any datagrams discarded while awaiting
reassembly.
InDelivers The total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).
OutRequests The total number of IP datagrams that local IP
user-protocols (including ICMP) supplied to IP in
requests for transmission. Note that this counter
does not include any datagrams counted in
ipForwDatagrams.
OutDiscards The number of output IP datagrams for which
no problem was encountered to prevent their
transmission to their destination, but that were
discarded (for example, for lack of buffer space).
Note that this counter includes datagrams counted
in ipForwDatagrams if any such packets met this
(discretionary) discard criterion.
OutNoRoutes 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 a host
cannot route because all of its default gateways are
down.
FragOKs The number of IP datagrams successfully fragmented
at this entity.
FragFails The number of IP datagrams discarded because they
needed to be fragmented at this entity but could not
be; for example, because their Don’t Fragment flag
was set.
