Parameter Description
Interface Statistics
Received Octets The total number of octets received on the interface, including framing
characters.
Transmitted Octets The total number of octets transmitted out of the interface, including
framing characters.
Received Errors The number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
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.
Transmitted Octets The total number of octets transmitted out of the interface, including
framing characters.
Transmitted Errors The number of outbound packets that could not be transmitted
because of errors.
Transmitted 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.
Transmitted Discarded
Packets
The number of outbound packets which were chosen to be 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.
