Statistics
- Discontinuity Time – The time on the most recent occasion at which any one or more of
this interface’s counters suffered a discontinuity or interruption of service.
- In Octets – The total number of octets received on the interface, including framing
characters.
- In Unicast Pkts – The number of packets, delivered by this sub-layer to a higher (sub-
)layer, which were not addressed to a multicast or broadcast address at this sub-layer.
- In Multicast Pkts – The number of packets, delivered by this sub-layer to a higher (sub-
)layer, which were addressed to a multicast address at this sub-layer.
- In Discards – The number of inbound packets which were chosen to be discard 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.
- In Errors – For packet-oriented interfaces, the number of inbound packets that contained
errors preventing them from being deliverable to a higher-layer protocol.
- Out Octets – The total number of octets transmitted out of the interface, including
framing characters.
- Out Unicast Pkts – The total number of packets that higher-level protocols requested 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.
- Out Discards – The number of outbound packets which were chosen to be discarded even
though no errors had been detected to prevent their being transmitted.
- Out Errors – For packet-oriented interfaces, the number of outbound packets that could
not be transmitted because of errors.
