Interface Statistics

including framing characters.
Received Unicast
Packets
The number of subnetwork-unicast packets delivered to
a higher-layer protocol.

The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast

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.
Received Discarded
Packets

preventing them from being deliverable to a higher-layer
protocol.

requested be transmitted to a subnetwork-unicast
address, including those that were discarded or not sent.
