Table 61 IP tab fields (continued)
Field Description
InAddrErrors The number of input datagrams discarded because the IP address
in their IP header's destination field was not a valid address to
be received at this entity. This count includes invalid addresses
(for example, 0.0.0.0) and addresses of unsupported Classes
(for example, Class E). For entities that are not IP Gateways and
therefore do not forward datagrams, this counter includes
datagrams discarded because the destination address was not
a local address.
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. In entities that do
not act as IP Gateways, this counter will include only those packets
that were Source-Routed by way of this entity and had 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 would include 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. This counter includes any datagrams a host
cannot route because all of its default gateways are down.
FragOKs The number of IP datagrams that have been successfully
fragmented at this entity.
FragFails The number of IP datagrams that have been discarded because
they needed to be fragmented at this entity but could not be, for
example, because their Don't Fragment flag was set.
