DHCPv6 client
The DHCPv6 client allows a host to request global unicast IPv6 address assignments from a DHCPv6 server. If there are multiple DHCPv6 servers, the client can select a server based on the preference value sent in DHCPv6 messages.
The DHCPv6 client can request that the server send only the configuration information. In this case, a router on the same interface (VLAN) as the host provides the global IPv6 address to the host through router advertisements.
NOTE:
If the switch is rebooted with a default configuration,
only the default DHCPv4 client is enabled on the default VLAN. The
DHCPv6 client has to be explicitly enabled on a VLAN using the command ipv6 address dhcp or ipv6 address autoconfig.
