The isis cpu-overload control disable command disables control on IS-IS cpu overload.
The undo isis cpu-overload control disable command enables control on IS-IS cpu overload.
By default, control on IS-IS cpu overload is enabled.
Usage Scenario
If a device's CPU is overloaded, each module needs to take necessary measures to control its own CPU usage accordingly. Upon receiving a CPU overload notification from the system, the IS-IS module controls the speeds of some internal computing processes and the establishment of neighbor relationships based on the CPU overload condition to enhance the resilience of IS-IS. In this case, new neighbor relationships cannot be established, and the established neighbor relationships are not affected.
Precautions
To minimize the impact of cpu overload on services, you are advised not to disable IS-IS cpu overload control.
