ACI: While creating the application profile, specify contract consumers and providers

(This is from ACI Built in Help)

You can associate contracts that were created earlier to create policy relationships between the EPGs.

When you name the provided and consumed contracts, verify that you give the same name for both provided and consumed contracts.

1. Note: The db, app, and web EPGs are displayed as icons.
   Click and drag across the APIC GUI window from the db EPG to the app EPG.
   The Add Consumed Contract dialog box is displayed.
2. In the Name field, from the drop-down list, choose sql contract. Click OK.
   This step enables the db EPG to provide the sql contract and the app EPG to consume the sql contract.
3. Click and drag across the APIC GUI screen from the app ePG to the web EPG.
   The Add Consumed Contract dialog box is displayed.
4. In the Name field, from the drop-down list, choose rmi contract. Click OK.
   This step enables the app EPG to provide the rmi contract and the web EPG to consume the rmi contract.
5. Click the web EPG icon, and click the + sign in the Provided Contracts area.
   The Add Provided Contract dialog box is displayed.
6. In the Name field, from the drop-down list, choose web contract. Click OK. Click Submit.
   You have created a three-tier application profile called OnlineStore.
7. To verify, in the Navigation pane, navigate to and click OnlineStore under Application Profiles.
   In the Work pane, you can see the three EPGs app, db, and web are displayed.
8. In the Work pane, choose Operational > Contracts.
   You can see the EPGs and contracts displayed in the order that they are consumed and provided.
