But if we want the APIC to manage the L4-L7 devices through apic then it would be service policy mode.

To meet the requirement of a single point of configuration for network elements and firewall policies in ACI, the engineer should define the service graph model as network policy mode. This approach leverages the Application Policy Infrastructure Controller (APIC) as a central management plane for both network and service configurations, simplifying the process of integrating Layer 4-7 services within the ACI fabric. Cisco ACI's approach to Layer 4-7 service insertion involves defining the service graph within the APIC. The APIC then uses this graph, along with the network policies, to orchestrate traffic flow and service insertion. By defining the service graph as network policy mode, the APIC handles the entire lifecycle of the service, from deployment to maintenance, ensuring a unified configuration experience.
