Hierarchy Level


Regulate the usage of CPU resources on services cards. When the CPU usage exceeds the configured value (percentage of the total available CPU resources), the system reduces the rate of new sessions so that the existing sessions are not affected by low CPU availability. The CPU utilization is constantly monitored, and if the CPU usage remains above the configured cpu-load-threshold value for a continuous period of 5 seconds, Junos OS reduces the session rate value configured at edit interfaces interface-name services-options session-limit rate (Interface Services) by 10%. This is repeated until the CPU utilization comes down to the configured limit.
