ACI: Applying a Service Graph Template to Endpoint Groups Using the GUI

(This is from ACI Built in Help)

You must have created the following things:

• Application endpoint groups
• A service graph template

The following procedure explains how to apply a service graph template to endpoint groups:

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 > template_name.
4. In the Work pane, choose Actions > Apply L4-L7 Service Graph Template.
   You will be associating a Layer 4 to Layer 7 service graph template to your consumer and provider endpoint groups.
5. In the Apply L4-L7 Service Graph Template To EPGs dialog, in the EPG Information section, complete the following fields:

   Name	Description
   Consumer EPG/External Network drop-down list	Choose a consumer endpoint group.
   Provider EPG/External Network drop-down list	Choose a provider endpoint group.

6. In the Contract Information section, complete the following fields:

   Name	Description
   Contract radio buttons	Choose to create a contract or choose an existing contract.
   Contract Name field	(Only for creating a contract) Enter the name of the contract.
   No Filter (Allow All Traffic) check box	(Only for creating a contract) Put a check in the box to allow all traffic, or remove the check from the box to filter traffic.
   Filter Entries	(Only for filtering traffic) Click + and enter the filter information, then click Update.
   Existing Contract With Subjects drop-down list	(Only for choosing an existing contract) Choose an existing contract.

7. Click Next.
8. In the Graph Template drop-down list, choose a service graph template.
9. (Only for a Layer 4 to Layer 7 device) In the L4L7_device_name Information section for each Layer 4 to Layer 7 device, complete the following fields:

   Name	Description
   Router Config drop-down list	(Only if you chose Route Peering for the consumer type or provider type) The router configuration to use for policy-based redirect.

   Consumer Connector

   Name	Description
   Type radio buttons	The connector type. The type can be: General Route Peering—Enables route peering on the device.
   BD drop-down list	(Only if you chose General for the type) Choose or create a bridge domain for the consumer connector. The bridge domain is used for the data path traffic.
   L3 Ext Network drop-down list	(Only if you chose Route Peering for the type) Choose a Layer 3 external (outside) network for the consumer connector.
   Cluster Interface drop-down list	Choose or create an interface for the consumer connector.

   Provider Connector

   Name	Description
   Type radio buttons	The connector type. The type can be: General Route Peering—Enables route peering on the device.
   BD drop-down list	(Only if you chose General for the type) Choose or create a bridge domain for the provider connector. The bridge domain is used for the data path traffic.
   L3 Ext Network drop-down list	(Only if you chose Route Peering for the type) Choose a Layer 3 external (outside) network for the provider connector.
   Cluster Interface drop-down list	Choose or create an interface for the provider connector.

   The Application Policy Infrastructure Controller (APIC) uses the chosen bridge domains for data path traffic between function nodes as required by the chosen service graph template. Refer to the online help for the service graph templates to learn more about how this bridge domain is used.
10. (Only for a copy device) In the copy_device_name Information section for each copy device, in the Cluster Interface drop-down list, choose the cluster interface that you defined for that copy device.
11. (Only for a managed Layer 4 to Layer 7 device) Click Next.
12. (Only for a managed Layer 4 to Layer 7 device) In the Parameters screen, in the Required Parameters tab, enter the names and values, as appropriate, for all of the required parameters.
13. Click Finish.
    You now have an active service graph template. The APIC populates the Layer 4 to Layer 7 parameters based on the chosen function profile and colors the mandatory parameters in green if they are configured correctly.
