Does the Device Support NAC Access Authentication for IPv6 Users?
The device supports NAC access authentication for IPv6 users. Clients have both IPv4 and IPv6 addresses typically. Configuring an access profile and an authentication profile, and applying NAC for IPv6 users are the same as those for IPv4 users. If a client only has an IPv6 address and an external Portal server is deployed to implement Portal authentication, you need to configure the free-rule acl ipv6 ipv6-acl-id command to allow the user to access the Portal server before authentication.
