Parameter

Description

 

 

Transmit Multicast

The total number of packets that higher-level protocols

Packets

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

The total number of packets that higher-level protocols

Packets

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

The number of outbound packets which were chosen

Packets

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.

 

 

Excessive Collisions

A count of frames for which transmission on a

 

particular interface fails due to excessive collisions. This

 

counter does not increment when the interface is

 

operating in full-duplex mode.

 

 

Single Collision Frames

The number of successfully transmitted frames for

 

which transmission is inhibited by exactly one collision.

 

 

Internal MAC Transmit

A count of frames for which transmission on a

Errors

particular interface fails due to an internal MAC

 

sublayer transmit error.
