Configuration – Network > DHCP Server > DHCP Options

sent to the DHCP client when requesting an IP address and other DHCP parameters. This is
useful for devices such as IP telephones that use specific strings. On the web page, these
(up to ten) options are configured using a table. The table contains the following fields:
