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.
Transmitted Errors The number of outbound packets that could not be transmitted because
of errors.
Received Unicast Packets The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
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.
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.
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.
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.
Transmitted Multicast
Packets The total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a multicast address at this
sub-layer, including those that were discarded or not sent.
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 Broadcast
Packets The total number of packets that higher-level protocols requested be
transmitted, and which were addressed to a broadcast address at this
sub-layer, including those that were discarded or not sent.
Received Unknown Packets The number of packets received via the interface which were discarded
because of an unknown or unsupported protocol.
Etherlike Statistics
Single Collision Frames The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
Multiple Collision Frames A count of successfully transmitted frames for which transmission is
inhibited by more than one collision.
Late Collisions The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
