Command History
Usage Guidelines The ipv6 dhcp server interface configuration command enables DHCPv6 service on a specified
interface.
The automatic keyword enables the system to automatically determine which pool to use when
allocating addresses for a client. When an IPv6 DHCP packet is received by the server, the server
determines if it was received from a DHCP relay or if it was directly received from the client. If the
packet was received from a relay, the server verifies the link-address field inside the packet associated
with the first relay that is closest to the client. The server matches this link-address against all address
prefix and link-address configurations in IPv6 DHCP pools to find the longest prefix match. The server
selects the pool associated with the longest match.
poolname (Optional) User-defined name for the IPv6 DHCP pool. The pool name can
be a symbolic string (such as Engineering) or an integer (such as 0).
automatic (Optional) Enable the server to automatically determine which pool to use
when allocating addresses for a client.
rapid-commit (Optional) Allow two-message exchange method.
preference value (Optional) The preference value carried in the preference option in the
advertise message sent by the server. The range is from 0 to 255. The
preference value default is 0.
allow-hint (Optional) Specify whether the server should consider client suggestions in
the SOLICIT message. By default, the server ignores client hints.
