Configure service chain actions in a data policy to route traffic through a service chain.

This task enables you to route traffic through a service chain by configuring service chain actions for a data policy.

Beginning with Cisco Catalyst SD-WAN Manager Release 20.13.1, you can route traffic through a service chain by configuring service chain actions for a data policy.

Procedure

From the Cisco SD-WAN Manager menu, choose Configuration > Policies.

Click Custom Options then click Traffic Policy under Centralized Policy.

Click the Traffic Data tab.

Click Add Policy and click Create New.

Click Sequence Type and choose Service Chaining from the Add Data Policy dialog box.

Click the Actions tab.

Click Service.

Configure the fields that the following table describes.

Table 1. Service Chain Action Fields
Field	Description
Service: Type	Choose a type of service for the service chain.
Service: VPN	VPN in which the service chain is hosted. Range: 1 to 65525, excluding 512. For details see the VRF range behavior change described here.
Service: TLOC IP	Enter the IP address of the Transport Locator (TLOC) for applying the services in the service chain.
Color	Choose a color for the TLOC.
Encapsulation	Choose the encapsulation type for the TLOC.
Service: TLOC List	Choose a predefined TLOC list to use for applying services to branch traffic.
Local	Check the Local check box if the service chain is hosted locally. If you do not check this check box, the service chain is hosted remotely.
Restrict	Check this option to cause packets to be dropped if the service chain goes down. f you configure this policy with the Local option, packets are dropped locally. If you configure this policy with the Remote option, packets are dropped on the remote host. This option is unchecked by default (traffic falls back to routing).

Service chain actions are configured in the data policy, enabling traffic to be routed through the specified service chain.
