About DHCP Properties

When you configure a NIOS appliance to f Anchorbookmark2237bookmark2237unction function as a DHCP server, you can set DHCP properties that control how the appliance operates and enable DHCP service for IPv4 and IPv6.
You can also specify configuration information the appliance includes in its IPv4 and IPv6 DHCP messages. When a DHCP server assigns an IP address to a client, it can include information the client needs to connect to the network and communicate with other hosts and devices on the network. You can set these properties at the Grid level and override them for a member, network, shared network, DHCP range, fixed address, IPv4 reservation, host address, or roaming host.
When you configure a DHCP object that has inherited DHCP properties, you can either keep the inherited properties or override them. The appliance displays the inherited values and the levels from which the DHCP properties are inherited. For information, see About DHCP Inheritance.
