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 (missynchronized 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

The total number of packets that higher-level protocols requested

Pkts.

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.

Single Collisions

The number of successfully transmitted frames for which

 

transmission is inhibited by exactly one collision.

Deferred

A count of frames for which the first transmission attempt on a

Transmissions

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 had either an FCS or alignment error.
