Interface Packets/Octets Statistics
Interface Error Statistics
Performance Logging
Bandwidth Util (%)—Percentage of bandwidth utilization.
In Octets—Total number of received octets including framing characters.
Out Octets—Total number of transmitted octets including framing characters.
In Unicast Pkts.—The number of packets delivered by this sublayer to a higher (sub)layer, which
were not addressed to a multicast or broadcast address at this sublayer.
Out Unicast Pkts.—The total number of packets that higher-level protocols requested be
transmitted, and that were not addressed to a multicast or broadcast address at this sublayer,
including those that were discarded or not sent.
In Packets/Sec—Five-minute exponentially decayed moving average of input packets per second.
Out Packets/Sec—Five-minute exponentially decayed moving average of output packets per second.
In Bits/Sec—Five-minute exponentially decayed moving average of input bits per second.
Out Bits/Sec—Five-minute exponentially decayed moving average of output bits per second.
CRC Error Pkts.—Number of input packets that had cyclic redundancy checksum errors.
In Discarded Pkts.—The number of inbound packets that were chosen to be discarded even though
no errors had been detected to prevent their being deliverable to a higher-layer protocol. One
possible reason for discarding such a packet could be to free up buffer space.
Out Discarded Pkts.—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.
In Dropped Pkts.—The number of packets dropped because the input queue was full.
Out Dropped Pkts.—The number of packets dropped because the output queue was full.
In Ignored Pkts.—Number of input packets that were ignored by this interface.
In Aborted Pkts.—Number of input packets that were aborted.
In Error Pkts.—The number of inbound packets that contained errors preventing them from being
delivered to a higher-layer protocol.
Out Error Pkts.—Number of outbound packets that could not be transmitted because of errors.
