IP tab fields
Field Description
InReceives The total number of input datagrams received from
interfaces, including those received in error.
InHdrErrors The number of input datagrams discarded due to
errors in their IP headers, including bad checksums,
version number mismatch, other format errors,
time-to-live exceeded, errors discovered in processing
their IP options.
InAddrErrors The number of input datagrams discarded because
the IP address in the IP header destination field
was not a valid address. This count includes invalid
addresses (for example, 0.0.0.0) and addresses of
unsupported Classes (for example, Class E). For
addresses 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. For addresses that do not act as
IP Gateways, this counter includes only those packets
that were Source-Routed by way of this address 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.
