IPv6 Wireless Network Configuration
If you configure the network settings on the phone for an IPv6 network, you can set up an IP address for the phone
by using SLAAC (ICMPv6), DHCPv6 or by manually entering an IP address. Ensure that your network environment
supports IPv6. Contact your ISP for more information.
When you enable both SLAAC and DHCPv6 on the phone, the server can specify the IP phone to obtain the IPv6
address and other network settings either from SLAAC or from DHCPv6, if the SLAAC server is not working, the
phone will try to obtain the IPv6 address and other network settings via DHCPv6.
The following table lists the parameters you can use to configure IPv6 wireless network.
