If one command is listed in multiple command sets, which permission takes precedence?

In the context of Cisco Identity Services Engine (ISE) policy configurations, the principle of command precedence plays a critical role in determining how rules are enforced. When one command appears in multiple command sets, the command that explicitly denies access will always take precedence over any permit commands.

This behavior is grounded in fundamental security practices, where an explicit denial is favored to ensure that any security risks are mitigated effectively. Therefore, if a command is included in both a deny and a permit context, the deny command overrides the permit, ensuring that access is restricted despite any permissive settings that may exist elsewhere in the configuration.

Recognizing this prioritization allows network administrators to design security policies with a clear understanding of how commands will be evaluated in practice, ensuring that critical security measures are reliably enforced without ambiguity.
