Parameter Description
IF Table Stats
Octets Input The total number of octets received on the interface, including framing
characters.
Octets Output The total number of octets transmitted out of the interface, including
framing characters.
Unicast Input The number of subnetwork-unicast packets delivered to a higher-layer
protocol.
Unicast Output 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.
Discard Input 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.
Error Input The number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
Error Output The number of outbound packets that could not be transmitted
because of errors.
Extended IF Table Stats
Multicast Input 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.
Multicast Output 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.
Broadcast Input 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.
Broadcast Output 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.
Etherlike Statistics
FCS Errors A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check. This count
does not include frames received with frame-too-long or frame-too-
short error.
Single Collision Frames The number of successfully transmitted frames for which transmission
is inhibited by exactly one collision.
Deferred Transmissions A count of frames for which the first transmission attempt on a
particular interface is delayed because the medium was busy.
Late Collisions The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
