firewall exceeded cpu-usage threshold
Function
The firewall exceeded cpu-usage threshold command configures the CPU usage threshold that triggers the interface to be automatically disabled.
The undo firewall exceeded cpu-usage threshold command restores the CPU usage threshold that triggers the interface to be automatically disabled to the default value.
Format
firewall exceeded cpu-usage threshold threshold-value
undo firewall exceeded cpu-usage threshold
Parameters
| Parameter | Description | Value |
|---|---|---|
| threshold-value | Specifies the CPU usage threshold. | The value is an integer ranging from 60 to 100, in percentage (%). The default value is 80. |
Usage Guidelines
When the CPU usage of the data plane reaches the threshold and keeps this status for 100 seconds, the device automatically disables interfaces in the list of interfaces that shall be automatically disabled and sends alarm ENTEXT_1.3.6.1.4.1.2011.5.25.31.2.0.31 hwEntityExtCPUOverInterfaceDown. To enable the automatic interface disabling function to take effect, you must run the firewall exceeded cpu-usage enable command to enable the function of automatic interface disabling when the CPU usage reaches the threshold. After the CPU usage of the data plane falls below the threshold, disabled interfaces cannot be automatically enabled. Instead, you need to manually enable them.
You can run the firewall exceeded cpu-usage shutdown interface command to configure the list of interfaces that can be automatically disabled.
