access-speed adjustment system-state threshold https-redirect

Function

The access-speed adjustment system-state threshold https-redirect command configures the CPU usage threshold that triggers the decrease of the flow establishment rate for HTTPS redirection and the CPU usage threshold for restoring the flow establishment rate of HTTPS redirection.

The undo access-speed adjustment system-state threshold https-redirect command restores the default value.

By default, the CPU usage threshold that triggers the decrease of the flow establishment rate for HTTPS redirection is 90%. The CPU usage threshold for restoring the flow establishment rate of HTTPS redirection is 85%.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

If the flow establishment rate for HTTPS redirection exceeds the threshold, the CPU usage may be high, which affects device performance. By default, the CPU usage threshold that triggers the decrease of the flow establishment rate for HTTPS redirection is 90%, and the CPU usage threshold that triggers a restoration of the flow establishment rate for HTTPS redirection is 85%.

To change the CPU usage threshold that triggers the decrease of the flow establishment rate for HTTPS redirection and the CPU usage threshold that triggers a restoration of that rate in order to prevent other services from being affected by a high CPU usage, run the access-speed adjustment system-state threshold https-redirect command.

Precautions

In VS mode, this command is supported only by the admin VS.
When the CPU usage is greater than the configured alarm threshold, the device decreases the HTTPS redirection flow creation rate. When the CPU usage is less than the resume threshold, the HTTPS redirection flow creation rate is called back.

Example

# Configure the CPU usage threshold that triggers the decrease of the flow establishment rate for HTTPS redirection as 85%, and the CPU usage threshold that triggers a restoration of the flow establishment rate for HTTPS redirection as 80%.
