Network requirements
As shown in Figure 76, configure VLAN-interface 2 on the switch to use DHCPv6 to obtain configuration
parameters from the DHCPv6 server. The parameters include IPv6 prefix, DNS server address, domain
name suffix, SIP server address, and SIP server domain name.

Configuration procedure
You must configure the DHCPv6 server first before configuring the DHCPv6 client. For information about
configuring DHCPv6 server, see "Configuring the DHCPv6 server."
