Parameters
ipv6: Specifies IPv6 portal users. Do not specify this keyword for IPv4 portal users.
Usage guidelines
With this feature enabled, users with static IP addresses cannot pass portal authentication to get
online.
To ensure that IPv6 users can pass portal authentication when this feature is enabled, disable the
temporary IPv6 address feature on terminal devices. Otherwise, IPv6 users will use temporary IPv6
addresses to access the IPv6 network and will fail portal authentication.

authentication. (Wired application).
