Proactive LM Threshold Configuration

Procedure 16-4.3: Proactive LM Threshold Configuration

Overview

Use this procedure to provision the LM/SES/UAS threshold values for a Proactive LM session on a selected MEP or to delete the LM/SES/UAS Threshold values for the Proactive LM session on a selected MEP.

LM/SES/UAS thresholds can be configured only when the associated proactive LM session is enabled.

This procedure:

Sets alarm thresholds for a proactive Loss Measurement session, for maximum or average Frame Loss Ratio measurement, Near-end or Far-end, 15-minute or 24-hour intervals.

The alarm is raised when a measurement equals or exceeds the cross threshold, which for maximum can occur anytime during a bin, and for average only at the end of a bin. The alarm is cleared when the measurement at the end of a bin is equal or less than the clear threshold.
Sets alarm thresholds for Severely Errored Second monitoring, for Unidirectional Near-end or Far-end, Bidirectional Near-end or Far-end, 15-minute or 24-hour intervals.

The alarm is raised when a counter equals or exceeds the cross threshold, which can occur anytime during a bin. The alarm is cleared when the counter at the end of a bin is equal or less than the clear threshold.
Sets alarm thresholds for Unavailable Seconds, for Unidirectional Near-end or Far-end, Bidirectional, 15-minute or 24-hour intervals.

The alarm is raised when a counter equals or exceeds the cross threshold, which can occur anytime during a bin. The alarm is cleared when the counter at the end of a bin is equal or less than the clear threshold.

Step

From the Navigation menu, select Service OA&M → Loss Measurement → Threshold Configuration to configure thresholds for the proactive loss measurement.

Equivalent CLI commands:

ethoam lm-threshold
ethoam ses-threshold
ethoam uas-threshold

Result:

The Proactive LM Threshold Configuration window displays current settings.

Enter the parameters as required. See Proactive LM Threshold parameters. Click Submit to execute the commands. Click Delete to delete both Cross and Clear Threshold values for the selected Monitoring Data in the selected Proactive LM session.

Proactive LM Threshold parameters

Parameter	Description	CLI command
Monitoring Data	This is a drop-down list for the monitoring data type. Valid values: LM, SES, UAS. The default value is "LM".	`ethoam lm-threshold` `ethoam ses-threshold` `ethoam uas-threshold`
Measurement Type	The type of measurement for the selected threshold presented in a drop-down list: LM Range — aN15, xN15, aF15, xF15, aN24, xN24, aF24, xF24 where: a = average, x = maximum, N = near-end, F = far-end, 15 = 15-minute counter, 24 = 24-hour counter. For example: aN15 is the Average Near-end FLR for the 15-minute counter. SES Range — uN15, bN15, uF15, bF15, uN24, bN24, uF24, bF24 where: u = unidirectional, b = bidirectional, N = near-end, F = far-end, 15 = 15-minute counter, 24 = 24-hour counter. For example: uN15 is the Unidirectional Near-end SES 15-minute counter. UAS Range — uN15, uF15, b15, uN24, uF24, b24 where: u = unidirectional, b = bidirectional, N = near-end, F = far-end, 15 = 15-minute counter, 24 = 24-hour counter. For example: uN15 is the Unidirectional Near-end UAS 15-minute counter. For each Measurement Type, one set of threshold values can be created per Proactive LM session. If the Proactive LM does not have any threshold value set yet, the default is the first one in the list. Otherwise, the default value is the first measurement type set in the system.	`ethoam lm-threshold <type>` `ethoam ses-threshold <type>` `ethoam uas-threshold <type>`
Cross Threshold	The threshold for generating a crossing alert. For LM: Range: 1 - 1000000000, units of 1E- 9 (0.0000001%) FLR. The default value is 300000000. For SES and uN15, bN15, uF15, bF15, the valid value is an integer in the range of 1-810. The default value is 15. For SES and uN24, bN24, uF24, bF24, the valid value is an integer in the range of 1-77760. The default value is 20. For UAS and uN15, uF15, b15, the valid value is an integer in the range of 1-900. The default value is 15. For UAS and uN24, uF24, b24, the valid value is an integer in the range of 1-86400. The default value is 20.	`ethoam lm-threshold cross <value>` `ethoam ses-threshold cross <value>` `ethoam uas-threshold cross <value>`
Clear Threshold	The threshold for clearing a crossing alert. The Clear Threshold must be lower than the Cross Threshold. For LM: Range: 1 - 1000000000, units of 1E- 9 (0.0000001%) FLR. The default value is 250000000. For SES and uN15, bN15, uF15, bF15, the valid value is an integer in the range of 0-809. The default value is 0. For SES and uN24, bN24, uF24, bF24, the valid value is an integer in the range of 1-77759. The default value is 0. For UAS and uN15, uF15, b15, the valid value is an integer in the range of 0-899. The default value is 0. For UAS and uN24, uF24, b24, the valid value is an integer in the range of 0-86399. The default value is 0.	`ethoam lm-threshold clear <value>` `ethoam ses-threshold clear <value>` `ethoam uas-threshold clear <value>`
Proactive LM (MD/MA/ MEPID)	This is a selectable field. The entry contains the comma separated fields of MD name, MA name, and MEPID for a Proactive LM. The drop-down list contains all MEPs which have the Proactive LM configured and enabled. The default display is for the first enabled Proactive LM in the system. When the Proactive LM selection is changed, the display data is updated automatically.
