ACI: Creating a Layer 4 to Layer 7 Service Graph Template Using the GUI

(This is from ACI Built in Help)

You must have configured a tenant.

A service graph template is a sequence of Layer 4 to Layer 7 functions, Layer 4 to Layer 7 devices, or copy devices and their associated configuration, which can be provided by using function profiles. The service graph template must be associated with a contract to be "rendered"—or configured—on the Layer 4 to Layer 7 device or copy device, and on the fabric.

1. On the menu bar, choose Tenants > All Tenants.
2. In the Work pane, double click the tenant's name.
3. In the Navigation pane, choose Tenant tenant_name > L4-L7 Services > L4-L7 Service Graph Templates.
4. In the Work pane, choose Actions > Create a L4-L7 Service Graph Template.
5. In the Create a L4-L7 Service Graph Template dialog box, in the Device Clusters section, if necessary create one or more Layer 4 to Layer 7 devices or copy devices. To create a device, click the +, choose Create L4-L7 Devices or Create Copy Devices, and follow the dialog.
6. Complete the following fields:

   Name	Description
   Graph Name field	Enter the name of the service graph template.
   Graph Type radio buttons	Choose to create a new service graph template or clone an existing service graph template.
   Existing Graphs drop-down list	(Only for cloning an existing service graph template) Choose an existing service graph template to clone. The remaining sections of this dialog become populated with the information from the cloned service graph template.

7. Optional: (Only for cloning an existing service graph template) If you want to remove any of the nodes from the cloned service graph template, right click a node that you want to remove and choose Remove Node.
8. To create a service node, drag a Layer 4 to Layer 7 device from the Device Clusters section and drop it between the consumer endpoint group and provider endpoint group. To create a copy node, drag and drop a copy device. This step is optional if you cloned an existing service graph template and the service graph template has all of the nodes that you want to use.
   You can drag and drop multiple devices to create multiple nodes. The maximum number of service nodes is 3, although you can drag and drop greater numbers of other devices.

   The location where you drop a copy device becomes the point in the data flow from where the copy device copies the traffic.
9. If you created one or more service nodes, in the device_name Information section for each Layer 4 to Layer 7 device, complete the fields. The fields vary depending on the device type.
10. Click Submit.
11. Optional: In the Navigation pane, click the service graph template.
    The work pane displays a graphic topology of the service graph template.
