The page includes the following fields:
Object Description
• Received Octets
The total number of octetts 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

buffer space.
• Received Unknown
Packets
The number of packets received via the interface which were discarded because
of an unknown or unsupported protocol.
