Description

Configure the BER threshold values (such as set and clear thresholds) at which different corrective actions must be triggered on a degraded interface.

Options

clear `clear- value`	The BER threshold value at which the degraded link is considered recovered and the corrective action applied to the interface is reverted. You can configure this value in the 1E–`n` format, where 1 is the mantissa (remains constant) and `n` is the exponent. For example, a threshold value of IE–3 refers to the BER threshold value of 1x10^-3. The supported exponent range is 1 through 16, and the default value is 12.
interval `interval-value`	The number of consecutive link degrade events that are considered before any corrective action is taken. The supported value range for the interval is 1 through 256, and the default interval is 10.
set `set- value`	The BER threshold value at which the link is considered degraded and a corrective action, specified by the user, is triggered. You can configure this value in the 1E–`n` format, where 1 is the mantissa (remains constant) and `n` is the exponent. For example, a threshold value of IE–3 refers to the BER threshold value of 1x10^-3. The supported exponent range is 1 through 16, and the default value is 7.
warning clear `warning-clear-value`	The link clear warning threshold. Every time this threshold value is reached, a system message is logged to indicate that the link degrade condition has been cleared on the interface. You can configure this value in the 1E–`n` format, where 1 is the mantissa (remains constant) and `n` is the exponent. For example, a threshold value of IE–3 refers to the BER threshold value of 1x10^-3. The supported exponent range is 1 through 16, and the default value is 11.
warning set `warning-set-value`	The link degrade warning threshold. Every time this threshold value is reached, a system message is logged to indicate that a link degrade has occurred on the interface. You can configure this value in the 1E–`n` format, where 1 is the mantissa (remains constant) and `n` is the exponent. For example, a threshold value of IE–3 refers to the BER threshold value of 1x10^-3. The supported exponent range is 1 through 16, and the default value is 9.

Note:

The lower the BER with high confidence level, the longer it takes to estimate it. In such cases, a few packet drops might be noticed (based on the bit error distribution) before a link degrade event is detected.
