Object  Description 
  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 Unknown 
Unicast Packets 
The number of packets received via the interface which is discarded because of 
an unknown or unsupported protocol. 
  Received Discards 
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. 
  Transmit Octets 
The total number of octets transmitted out of the interface, including framing 
characters. 
  Transmit Unicast 
Packets 
The total number of packets that higher-level protocols requested is transmitted 
to a subnetwork-unicast address, including those that were discarded or not sent.
  Transmit Unknown 
Unicast Packets 
The total number of packets that higher-level protocols requested is transmitted 
to a subnetwork-unicast address, including those that were discarded or not sent.
  Transmit Discards 
Packets 
The number of inbound packets which is chosen to be discarded even though no 
errors have been detected to prevent from being delivered to a higher-layer 
protocol. One possible reason for discarding such a packet could be to free up 
buffer space. 
  Received Multicast 
Packets 
The number of packets, delivered by this sub-layer to a higher (sub-) layer, is 
addressed to a multicast address at this sub-layer. 
  Received Broadcast 
The number of packets, delivered by this sub-layer to a higher (sub-) layer, 
86
