Explanation

In Cisco ACI (Application Centric Infrastructure), L4-L7 services refer to the insertion of network service appliances - such as firewalls, load balancers, and web proxies - into the traffic path using service graphs. Placing a web server in front of a firewall represents an L4-L7 service chaining topology, where traffic is steered through defined service nodes. ACI's service graph feature automates the stitching of these L4-L7 devices into the forwarding path. An Application Profile (A) is an ACI logical construct that groups EPGs (Endpoint Groups) and contracts but does not define service device placement in the traffic path.
