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.
To configure the network service:
If the design is not currently visible on the Build page:
The list of saved and published designs appears.
The Build page appears, displaying the service chain design.
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.
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.
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.
The Service page closes.
