Show Ip Dhcp Client-Identifier - Edge-Core ECS3510-26P Management Manual

DHCPv6 clients build a list of servers by sending a solicit message and
◆
collecting advertised message replies. These servers are then ranked
based on their advertised preference value. If the client needs to
acquire prefixes from servers, only servers that have advertised
prefixes are considered.
If the rapid commit option has been enabled on the switch using the
◆
ipv6 dhcp client rapid-commit vlan
server, message exchange can be reduced from the normal four step
process to a two-step exchange of only solicit and reply messages.

DHCPv6 clients and servers are identified by a DHCP Unique Identifier
(DUID) included in the client identifier and server identifier options. Static
or dynamic address prefixes may be assigned by a DHCPv6 server based
on the client's DUID.
This combination is known as DHCPv6 stateless, in which a DHCPv6
server does not assign stateful addresses to IPv6 hosts, but does
assign stateless configuration settings.
