In Unicast Pkts. The number of subnetwork-unicast packets delivered to a higher-layer protocol.
In Non-Unicast Pkts. The number of non-unicast (that is, subnetwork- broadcast or
subnetwork-multicast) packets delivered to a higher-layer protocol.
In Discards 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.
In Errors The number of inbound packets that contained errors preventing them from
being deliverable to a higher-layer protocol.
Alignment Errors The number of alignment errors (mis-synchronized data packets).
Out Octets
The total number of octets transmitted out of the interface, including framing
characters.
Out Unicast Pkts. 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.
Out Non-Unicast Pkts. The total number of packets that higher-level protocols requested be
transmitted to a non- unicast (that is, a subnetwork-broadcast or
subnetwork-multicast) address, including those that were discarded or not sent.
Out Discards 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.
Out Errors The number of outbound packets that could not be transmitted because of
errors.
CRC Errors Number of Ethernet Cyclic Redundancy Check errors detected by this device.
Ethernet-Like
Single Collisions 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.
Excessive Collisions The number of frames for which transmission failed due to excessive collisions.
Drop Events The total number of events in which packets were dropped due to lack of
resources.
Octets Number of octets passing through this port.
Multiple Collisions 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.
Carrier Sense Errors The number of times that the carrier sense condition was lost or never asserted
when attempting to transmit a frame.
