Parameter Description
Interface Statistics
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 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 protocol. One possible reason for discarding such a packet
could be to free up buffer space.
Received Unknown Packets The number of packets received via the interface which were discarded
because of an unknown or unsupported protocol.
Received Errors The number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
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 be
transmitted to a subnetwork-unicast address, including those that were
discarded or not sent.
Transmit 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.
Transmit 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.
Transmit 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.
Transmit Errors The number of outbound packets that could not be transmitted because of
errors.
Etherlike Statistics
Alignment Errors The number of alignment errors (missynchronized data packets).
Late Collisions The number of times that a collision is detected later than 512 bit-times
into the transmission of a packet.
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.
