Inbound Non-Unicast Packets
The number of non-unicast (subnetwork-broadcast or
subnetwork-multicast) packets delivered to a
higher-layer protocol.
Inbound Discards The number of inbound packets that were 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.
Inbound Errors The number of inbound packets that contained errors
preventing them from being deliverable to a
higher-layer protocol.
Inbound Unknown Protocols
The number of packets received via the interface which
were discarded because of an unknown or unsupported
protocol.
Outbound Octets The total number of octets transmitted out of the
interface, including framing characters.
Outbound Unicast Packets
The total number of packets that higher-level protocols
requested be transmitted to a subnetwork-unicast
address, including those that were discarded or not
sent.
Outbound Non-Unicast Packets
The total number of packets that higher-level protocols
requested be transmitted to a non-unicast (a
subnetwork-broadcast or subnetwork-multicast)
address, including those that were discarded or not
sent.
Outbound Discards
The number of outbound packets that were 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.
Outbound Errors The number of outbound packets that could not be
transmitted because of errors.
