IF statistics
Statistics
Description
ifInErrors
For packet-oriented interfaces, the number of inbound packets that contained errors
preventing them from being delivered to a higher-layer protocol.
For character-oriented or fixed-length interfaces, the number of inbound transmission units
that contained errors preventing them from being deliverable to a higher-layer protocol.
ifInDiscards
The number of inbound packets that were chosen to be discarded even though no errors
were detected to prevent their being delivered to a higher-layer protocol. One possible
reason for discarding such a packet could be to free up buffer space.
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 53
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 Time-To-Live (TTL) field of the IP header of datagrams
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.
