Using the cpu-usage threshold command, you can set the alarm threshold and alarm recovery threshold of CPU usage.
Using the undo cpu-usage threshold command, you can restore the alarm threshold and alarm recovery threshold of CPU usage.
By default, the alarm threshold of CPU usage is 95% and alarm recovery threshold is 80%.

undo cpu-usage threshold [ threshold-value [ restore [ restore-threshold-value ] ] ] [ slot slot-id ]
| Parameter | Description | Value |
|---|---|---|
| threshold threshold-value | Specifies the alarm threshold of CPU usage. |
The value is an integer that ranges from 2 to 100. The default value is 95. |
| restore restore-threshold-value | Specifies the alarm recovery threshold of CPU usage. |
The value is an integer that ranges from 1 to 99. The alarm recovery threshold must be smaller than the alarm threshold. |
| slot slot-id | Specifies a slot ID. |
The value depends on the device configuration. |
When the CPU usage exceeds the alarm threshold, a log is recorded. When the CPU usage reduces by equal to or smaller than 5% and exceeds the threshold again, no log is recorded. A log is recorded only when the CPU usage is reduced by greater than 5% and reaches the threshold again. Through log information, you can know the CPU usage more conveniently.
If slot slot-id is not configured, the alarm threshold and alarm recovery threshold of CPU usage are set. In addition, the system automatically synchronizes the threshold on the master switch with those on the member switches.
