Which feature is used to program policy CAM on a leaf switch without sending traffic from VM to the leaf?

Immediate resolution immediacy is not a standard ACI term or feature related to policy CAM programming.

Immediate deployment immediacy means that ACI policies and forwarding entries are programmed onto the leaf switch as soon as the associated End-Point Group (EPG) is bound to an interface or VMM domain, regardless of whether actual traffic from a VM has been detected. This proactive programming ensures that policies are ready before traffic arrives.

On-demand deployment immediacy means policies are programmed only when an endpoint's traffic is first detected on the leaf switch, which is the opposite of the requirement.
