Step 6 Click Submit.

Configure Downloadable IP ACLs

Downloadable IP Access Control Lists (dACLs) are access lists that can be downloaded to enforce the network authorization of a host. Downloadable ACLs dynamically download Layer 3 and Layer 4 access control entries (ACEs) to a router; or, to a VPN concentrator and merge them with the default interface ACL.

In ACS 4.2, you can download access lists to specific devices or device groups.

You can define an access list that contains one or more dACLs and later download the list to network devices, based on their assignments to user groups. Before you define dACLs, enable dACLs.

Each Assessment Result (system posture token), according to its definition, should have its own ACL, which contains one or more Access Control Entries (ACEs) that will instruct the NAC network device (router) to block packets from going to a specific destination or allow packets to reach a

specific destination.
