Table 45 IF statistics
Statistics Description
ifInUnknownProtos For packet-oriented interfaces, the number of packets received via the interfaces that were discarded
because of an unknown or unsupported protocol.
For character-oriented or fixed-length interfaces which support protocol multiplexing the number of
transmission units received via the interface which were discarded because of an unknown or
unsupported protocol.
For any interface that does not support protocol multiplexing, this counter will always be zero (0).
ifOutErrors For packet-oriented interfaces, the number of outbound packets that could not be transmitted
because of errors.
For character-oriented or fixed-length interfaces, the number of outbound transmission units that
could not be transmitted because of errors.
ifOutDiscards The number of outbound packets, which were chosen to be discarded even though no errors had
been detected to prevent their being transmitted. One possible reason for discarding such a packet
could be to free up buffer space.
IP statistics are described in the following table:
Table 46 IP Statistics
Statistic Description
ipInReceives The total number of input datagrams received from interfaces, including those received in error.
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.
ipInDelivers The total number of input datagrams successfully delivered to IP user protocols (including ICMP).
ipDefaultTTL The default value inserted into the
originated at this entity (the switch), whenever a TTL value is not supplied by the transport layer
protocol.
ipInUnknownProtos The number of locally addressed datagrams received successfully but discarded because of an
unknown or unsupported protocol.
ipOutRequests The total number of IP datagrams which 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
ipOutDiscards The number of output IP datagrams for which no problem was encountered to prevent their
transmission to their destination, but which were discarded (for example, for lack of buffer space).
Note that this counter would include datagrams counted in
packets met this (discretionary) discard criterion.
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.
