Table 1 lists the DHCPv6 Server Configuration parameters.
Table 1 DHCPv6 Server Configuration parameters
Parameters Description
IPv6 address Indicates the management IP address of IPv6. The default value is fe80::1. To configure the management IP address
for IPv4, choose LAN > LAN Host Configuration.
Parent prefix Indicates the parent prefix source. Usually an Internet-type WAN port is used as the parent prefix source. By default,
the first created IPv6 Internet WAN port is used as the parent prefix source. If the value is left empty, no prefix will be
obtained, which may result in service unavailability.
Child prefix mask Used for LAN IP address allocation. This parameter needs to be configured when the obtained prefix is shorter than 64
bits. For example, if the obtained prefix is 2001:db8:2222::/48, and the child prefix mask value is set to
2001:db8:1:3333::/64, the generated IPv6 address prefix is2001:db8:2222:3333::/64.
Address/Prefix assignment mode Indicates the address/prefix assignment mode. It can be set to DHCPv6 or stateless address autoconfiguration
(SLAAC). When it is set to SLAAC, ULA Mode must be set.
DHCPv6: indicates that the LAN-side host obtains addresses in DHCPv6 mode.
SLAAC: indicates that the LAN-side host obtains addresses in ND mode. In SLAAC mode, the host
automatically configures addresses. The address information contains the prefix advertised by the local
router and the interface identifier of the host. If there is no router on the link, the host has to automatically
configure the link local address to communicate with local nodes.
Other information assignment mode Indicates the assignment mode of other information. Other information refers to the IPv6 address in payloads of
packets such as DNS packets.
DHCPv6: indicates that the address is obtained in DHCPv6 mode.
SLAAC: indicates that the address is obtained in ND mode.
