total number of burst errors reported in the Soft Error

 

Report MAC frame.

ACErrors

This error is flagged when a frame is copied by an

 

adapter to which it was not addressed. Address

 

Copied Errors or ACErrors will increment the error

 

counter only for the nearest upstream neighbor of the

 

station reporting the error. This statistic is found in

 

the total number of ACErrors reported in the Soft Error

 

Report MAC frame.

Abort Error

This keeps track of the number of times a ring station

 

transmits an abort delimiter to abort a frame it

 

transmitted. This statistic is found in the total number

 

of Abort errors reported in the Soft Error Report MAC

 

frame.

Lost Frame Error

Represents how often frames transmitted by a

 

particular ring station fail to return to it and thus the

 

active monitor has to issue a new token. This statistic

 

is found in the total number of Lost Frame errors

 

reported in the Soft Error Report MAC frame.

Congestion Error

Occurs when a station cannot copy the frame

 

addressed to it due to lack of receive buffers on the

 

adapter. This is commonly referred to as Receiver

 

Congestion. Sometimes the problem may not actually

 

be in the receiving station, but in one or more stations

 

sending excessive number of frames to the congested

 

adapter. This statistic is found in the total number of

 

Congestion errors reported in the Soft Error Report

 

MAC frame.

Frame-Copied Error

The Frame Copied Soft error counter is incremented

 

each time a destination station sees a frame

 

addressed to it and the Address Recognized and

 

Frame Copied bits set on. Under normal conditions

 

this would indicate a duplicate address in the network,

 

since stations would turn on those bits when they

 

recognize a frame addressed to them and can copy it.

 

However, with bridges the scenario is changed. As a

 

bridge sees a frame that it must copy, it marks the

 

AC/AC bits on the Frame Status field on the local ring.

 

When the frame is placed on the remote ring those

 

fields are cleared. Therefore on a ring with bridges it

 

is not uncommon to see many Frame Copied soft

 

errors. Also, be aware that the Frame Status field is

 

the only type of frame checked to verify that the frame

 

has successfully reached its destination. LLC frames

 

depend on several timers (T1/T2/Ti) to do link-level

 

acknowledgments and even though the Frame Status

 

field is updated, it will not be checked at the adapter

 

level.

 

This statistic is found in the total number of Frame

 

Copied errors reported in the Soft Error Report MAC

 

frame.
