Limitation in NEN 2.4.0
Enforcement Boundaries not supported for NENs
The PCE doesn't support Enforcement Boundary policies for devices attached to the NEN.
Enforcement Boundaries are a security policy model available in the Core PCE for broadly managing communication across a set of workloads, ports, and/or IP addresses. They allow you to define the end state and then the PCE implements an Enforcement Boundary to create the appropriate native firewall rules. For more, see Enforcement Boundaries .
