Configuring Network Services

When you are designing a service chain or after you have designed a service chain, you can configure settings for the VNFs in the chain. The configuration settings you can configure are specified in Configuration Designer and the values for the settings are specified in Resource Designer. The settings that you configure are:

  • The virtual container in which the VNF resides.

  • The network functions, such as NAT or firewall.

The settings that you can configure depend on the actual VNF. Manual configurations are optional and override automatic configurations specified by the Contrail Service Orchestration (CSO) deployment script, other CSO components, or default settings that you configured with Resource Designer.

Procedure

To configure the network service:

  1. View the service chain design on the Build page.

    If the design is not currently visible on the Build page:

    Procedure

    1. Click Home in the toolbar and Designs in the left navigation bar.

      The list of saved and published designs appears.

    2. Click Edit for the network service you want to configure.

      The Build page appears, displaying the service chain design.

  2. Click Function Configuration.

    The Service page appears, displaying the VNFs in the service chain and the Base Configure tab for the first VNF in the Functional Service Design workspace.

  3. Specify the settings on the Base Configure tab.

    This action configures the virtual machine in which the VNF resides.

    Best Practice 

    • Complete all the settings in the Base Configure tab to optimize your deployment. End users can see these settings in Customer Portal or custom access software and should not override them.

    • Configure few example settings for the service. These example settings must be generic and not network-specific. End users can configure service settings specific to their networks in Customer Portal.

  4. (Optional) Specify settings on the other tabs for this VNF to customize a particular function such as NAT.

    End users can customize their own services with these settings in Customer Portal. Settings that end users specify in Customer Portal override conflicting settings that you specify in Network Service Designer.

  5. Click the next VNF icon in the Configuration page.
  6. Repeat Step 3 and Step 4.
  7. Repeat Steps 5 through 7 for each VNF in the chain.
  8. Click OK.

    The Service page closes.
