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. |
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.
