Alarm Configuration

The Alarm Type list displays the variables available for alarms, the current status of each alarm, and the current threshold setting. To change the status or threshold for an alarm, you must first select it in this list. You can set an alarm threshold for the following variables:

Ring Purges

The number of times the active monitor has purged the

 

ring since the network was created, or since the

 

TRMMIM was last reset. This includes the purge at the

 

end of the active monitor selection process; however, the

 

count is not reset when the active monitor changes.

Active Monitor

The number of times a duplicate active monitor has been

Participant

detected on the ring. When any station which considers

Errors

itself to be the active monitor receives a ring purge or

 

AMP (active monitor present) frame that it did not

 

transmit, it will become a standby monitor. If this process

 

leaves the ring without an active monitor (because both

 

active monitors have switched to standby mode), the

 

monitor contention process will begin.

Token Errors

The number of times the active monitor either does not

 

see a token circulating on the ring before its TVX (Timer,

 

Valid Transmission) timer expires (e.g., a Lost Frame

 

error has occurred), or sees a recirculating frame or

 

token. Each time a token error is noted, the active

 

monitor purges the ring and issues a new token.

Claim Token

The number of times a claim token has been released by a

Errors

station on the ring. A claim token is released when a

 

station detects that the active monitor is missing or

 

malfunctioning, or following a beaconing condition; the

 

issuing of a claim token initiates the monitor contention

 

process, through which a new active monitor will be

 

chosen.

Lost Frames

The number of times a station’s TRR (Timer, Return to

 

Repeat) timer expires before the frame it is transmitting

 

returns. This timer, which is set to 4.1 milliseconds,

 

ensures that each station returns to the data repeat state

 

after transmitting: retrieves its token, strips it of data,

 

and issues a new token. Lost frame errors will cause the

 

active monitor to initiate the ring purge process and issue

 

a new token; these errors are usually caused by stations

 

entering or leaving the ring while a frame is circulating

 

(since stations entering or leaving briefly throw the ring

 

out of sync).

Frame Count

The number of frames detected on the ring.
