After you deploy a Layer 4 "" Layer 7 service graph in Cisco ACI, where do you modify the parameters of the Layer 4 "" Layer 7 device(s)?

In Cisco ACI, a Layer 4-7 service graph is a means of deploying network services such as firewalls, load balancers, and other network appliances. The service graph consists of two or more virtual network devices or nodes that are connected together to form a chain. The service graph nodes can be physical or virtual appliances that provide Layer 4-7 network services.
After you have deployed a Layer 4-7 service graph, you may need to modify the parameters of the service graph devices. The parameters of a service graph device can include things like the IP address, port number, and other settings that control how the device operates within the service graph.
To modify the parameters of a Layer 4-7 service graph device in Cisco ACI, you need to navigate to the Deployed Graph Instance. The Deployed Graph Instance is the instance of the service graph that has been deployed in the network. It contains all the devices that are part of the service graph, and it allows you to configure the parameters of each device.
When you select the Deployed Graph Instance, you can then navigate to the Service Graph Template. The Service Graph Template is the blueprint for the service graph, and it contains all the configuration settings for the service graph nodes. From the Service Graph Template, you can modify the settings for each service graph node, including the Layer 4-7 devices.
You can also modify the Layer 4-7 service parameters for a particular EPG (End Point Group) in Cisco ACI. An EPG is a logical grouping of endpoints that share common network requirements. The Provider EPG is the EPG that provides the service graph nodes, while the Consumer EPG is the EPG that consumes the services provided by the service graph nodes. To modify the Layer 4-7 service parameters for an EPG, you can navigate to the EPG and modify the settings in the L4-L7 Service Parameters section.
In summary, to modify the parameters of a Layer 4-7 service graph device in Cisco ACI, you can do so under the Service Graph Template, Provider EPG, Consumer EPG, or Deployed Graph Instance. However, the most direct and comprehensive way to modify these parameters is under the Deployed Graph Instance.
