4.3.6.2.5 Enabling/Disabling the Rate Limiting for the NPU
You can disable or enable the rate limiting feature for the NPU. When this feature
is disabled, rate-limiting for all applications is in the "not-in-service" state. When
you enable this feature, the last saved configuration parameters for all
applications (pre-defined, user-defined, and all others) is used.
By default, this feature is enabled for the NPU.

NOTECAUTION
When you disable rate limiting for the entire system, it is disabled for all applications, pre-defined,
user-defined, and all others, and any application can use 100% of the NPU’s capacity, thereby
making it vulnerable to attack from hostile applications. To disable rate limiting for a specific
user-defined and pre-defined application, refer
Section 4.3.6.2.2 and Section 4.3.6.2.3.
