Parameters
ipv6: Enables IPv6 portal authentication. Do not specify this keyword for IPv4 portal authentication.
method: Specifies an authentication mode:
• direct—Direct authentication.
• layer3—Cross-subnet authentication.
• redhcp—Re-DHCP authentication.
Usage guidelines
Make sure the device supports IPv6 ACL and IPv6 forwarding before you enable IPv6 portal
authentication on the interface.
IPv6 portal authentication does not support the re-DHCP authentication mode.
Do not add an authentication-enabled interface to an aggregation group. Otherwise, portal
authentication cannot take effect on the interface.
You can enable both IPv4 and IPv6 portal authentication on an interface.

# Enable direct IPv4 portal authentication on interface GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
