Table 63 Interface Statistics for a Port - Input
Statistic Description
HC BcastPkts The number of packets, delivered by this sub layer to a higher sub layer, which were
addressed to a broadcast address at this sub layer.
HC MCastPkts The total number of packets that higher-level protocols requested to be transmitted, and
which were addressed to a multicast address at this sub layer, including those that were
discarded or not sent. For a MAC layer protocol, this includes both Group and
Functional addresses.
Discards The number of inbound packets that were chosen to be discarded even though no errors
had been 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.
Errors 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.
Interface (“if”) Statistics - Output
The following table describes the interface output statistics of the selected port:
Table 64 Interface Statistics for a Port - Output
Statistic Description
HC Octets The total number of octets transmitted out of the interface, including framing characters.
HC UCastPkts 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 sub layer, including
those that were discarded or not sent.
HC BcastPkts The total number of packets that higher-level protocols requested to be transmitted, and
which were addressed to a broadcast address at this sub layer, including those that were
discarded or not sent. This object is a 64-bit version of ifOutBroadcastPkts.
HC MCastPkts The total number of packets that higher-level protocols requested to be transmitted, and
which were addressed to a multicast address at this sub layer, including those that were
discarded or not sent. For a MAC layer protocol, this includes both Group and
Functional addresses. This object is a 64-bit version of ifOutMulticastPkts.
Discards The number of outbound packets that 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.
Errors 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.
