Statistics Description
ipInReceives The total number of input datagrams received from interfaces,
including those received in error.
ipInHdrErrors 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, and so forth.
ipInAddrErrors 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 (the switch). This count includes invalid addresses (for
example, 0.0.0.0) and addresses of unsupported Classes (for example,
Class E). For entities which are not IP Gateways and therefore do not
forward datagrams, this counter includes datagrams discarded because
the destination address was not a local address.
ipInUnknownProtos The number of locally addressed datagrams received successfully but
discarded because of an unknown or unsupported protocol.
ipInDiscards The number of input IP datagrams for which no problems were
encountered to prevent their continued processing, but which were
discarded (for example, for lack of buffer space). Note that this counter
does not include any datagrams discarded while awaiting re-assembly.
