Statistical Values
Parameter Description
Interface Statistics
Received Octets The total number of octets received on the interface,
including framing characters.
Received Unicast Packets The number of subnetwork-unicast packets delivered
to a higher-layer protocol.
Received Multicast
Packets 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.
Received Broadcast
Packets 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 The number of inbound packets which 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.
Received Unknown
Packets The number of packets received via the interface
which were discarded because of an unknown or
unsupported protocol.
Received Errors The number of inbound packets that contained errors
preventing them from being deliverable to a
higher-layer protocol.
