Token Ring Alarms

NOTE

When the Alarm Limits window is invoked, the Station Errors fields do not present any values. This is because it is possible that station-level alarm limits have been set at individual stations (via the Station Alarm Limits window) that may differ from those set at other individual stations or at the ring level. Refer to the Station Alarm Limits windows for individual stations to view their current station-level alarm limits.

The following thresholds, listed in the section of the window labeled Station Errors, are based on the number of occurrences of the selected event detected by the station within a user-defined time interval.

Line	The threshold of line errors detected by the selected
	station port. These indicate a non-data bit between the
	starting and ending delimiters of data, or an FCS error.
	The default value is 2.
Internal	The threshold of recoverable internal errors detected by
	the selected port, indicating that the Network Interface
	Card of its attached station may be in marginal operating
	condition. The default value is 1.
Burst	The threshold of burst errors detected by the selected
	station port. These signify a bit information-encoding
	error (no transitions between 0 and 1 over five half-bit
	times). The default value is 10.
A.C.	The threshold of frames detected by the selected station
	port that contain errors in the A or C bits. The default
	value is 2.
Rx Congestion	The threshold at which the port cannot copy a frame
	addressed to it because of a lack of internal buffering.
	The default value is 124.

Setting Ring-Level Alarm Limits

To set an alarm:

1.If you wish to alter the default threshold values, place the text cursor into the desired alarm event field, and type in the threshold value.

2.To enable an alarm, click on the checkbox next to the desired alarm event field. An X in the checkbox indicates that the alarm is enabled.

3.Click on the clock icon next to the Within: field. A New Alarm Timebase text box will appear. In this text box, you enter the time interval for the specified number of events to occur before the alarm is activated.
