Syntax
portal ipv6 free-all except destination ipv6-network-address prefix-length
undo portal ipv6 free-all except destination [ ipv6-network-address ]
Default
No IPv6 portal authentication destination subnet is configured on the interface. Portal users must pass
portal authentication to access any IPv6 subnet.

Parameters
ipv6-network-address: Specifies an IPv6 portal authentication destination subnet.
prefix-length: Specifies the prefix length of the IPv6 subnet, in the range of 0 to 128.
Usage guidelines
Portal users on the interface are authenticated when accessing the specified authentication destination
subnet (except IP addresses and subnets specified in portal-free rules). The users can access other subnets
without portal authentication.
You can configure multiple authentication destination subnets.
If you do not specify the ipv6-network-address argument in the undo portal ipv6 free-all except
destination command, this commands deletes all IPv6 portal authentication destination subnets on the
interface.
Re-DHCP authentication does not support authentication destination subnets.
If you configure both an authentication source subnet and an authentication destination subnet on an
interface, only the authentication destination subnet takes effect.
Examples
# Configure an IPv6 portal authentication destination subnet of 1::2/16 on interface GigabitEthernet
2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname–GigabitEthernet2/1/1] portal ipv6 free-all except destination 1::2 16
