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.
Fragments
The total number of frames received that were less than 64 octets in
length (excluding framing bits, but including FCS octets) and
contained either an FCS or alignment error.
Jabbers
The total number of frames received that were longer than 1518
octets (excluding framing bits, but including FCS octets), and
contained either an FCS or alignment error.
