The following table describes the IP statistics:
Table 44 IP statistics
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 on.
ipInAddrErrors The number of input datagrams discarded because the IP address in their IP header
destination field was not a valid address to be received at this 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.
