TCP/IP Statistics (IF and IP Statistics)
To display the following form, go to the Management Processor Statistics form. Select one of the following: IF
Stats, IP Stats, ICMP Stats, or TCP Stats.
The following table describes the interface statistics:

Statistics
Description
ifInOctets
The total number of octets received on the interface, including framing characters.
ifInUcastPkts
The number of packets, delivered by this sublayer to a higher sublayer, which were not
addressed to a multicast or broadcast address at this sublayer.
ifInNUCastPkts
The number of packets, delivered by this sublayer to a higher sublayer, which were addressed to
a multicast or broadcast address at this sublayer. This object is deprecated in favor of
ifInMulticastPkts and ifInBroadcastPkts.
ifOutOctets
The total number of octets transmitted out of the interface, including framing characters.
ifOutUcastPkts
The total number of packets that higher-level protocols requested to be transmitted, and which
were not addressed to a multicast or broadcast address at this sublayer, including those that
were discarded or not sent.
ifOutNUcastPkts
The total number of packets that higher-level protocols requested to be transmitted, and which
were addressed to a multicast or broadcast address at this sublayer, including those that were
discarded or not sent.
This object is deprecated in favor of ifOutMulticastPkts and ifOutBroadcastPkts.
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).
