anti-ddos interface-limit cpu-usage

Function

The anti-ddos interface-limit cpu-usage command sets the SPU CPU usage threshold that triggers LPU rate limit.

The anti-ddos interface-limit start-delay command sets the delay time before enabling and disabling LPU rate limit when the CPU usage reaches the alarm threshold.

Format

anti-ddos interface-limit { cpu-usage cpu-usage | start-delay start-delay end-delay delay-time }

Parameters

Parameter	Description	Value
cpu-usage	Specifies the SPU CPU usage threshold that triggers LPU rate limit.	The value is an integer ranging from 25 to 100. The default value is 80.
start-delay	Specifies the delay time before enabling LPU rate limit when the CPU usage reaches the alarm threshold.	The value is an integer ranging from 1 to 254, in seconds. The default value is 5 seconds.
delay-time	Specifies the delay time before disabling LPU rate limit when the CPU usage falls below the alarm threshold.	The value is an integer ranging from 1 to 3600, in seconds. The default value is 1800 seconds.
