The fib threshold-alarm command enables the alarm function for IPv4 route prefix usage and sets the alarm threshold.
The undo fib threshold-alarm command restores the default alarm threshold.
By default, the alarm function for IPv4 route prefix usage is enabled. The upper alarm threshold is 85% and the lower alarm threshold is 75%.

| Parameter | Description | Value |
|---|---|---|
upper-limit upper-limit-value |
Sets the upper alarm threshold for IPv4 route prefix usage. |
The value is an integer that ranges from 1 to 100, in percentage. |
lower-limit lower-limit-value |
Sets the lower alarm threshold for IPv4 route prefix usage. |
The value is an integer that ranges from 1 to 100, in percentage. |
Usage Scenario
Precautions
In versions earlier than V200R019C00SPC300, the upper alarm threshold for the IPv4 route prefix usage can be greater than or equal to the lower alarm threshold. In V200R019C00SPC300 and later versions, the upper alarm threshold for the IPv4 route prefix usage must be greater than the lower alarm threshold. If the upper alarm threshold for the IPv4 route prefix usage is configured to be equal to the lower alarm threshold on a switch running a version earlier than V200R019C00SPC300, the configuration will be lost after the switch is upgraded to V200R019C00SPC300 or a later version, and the upper and lower alarm thresholds will be restored to the default settings.
