3.6.4 DHCP Relay Agent

If there is an Ethernet device that performs the DHCP server function for your network, then you can configure the Prestige as a DHCP relay agent. When the switch receives a request from a computer on your network, it contacts the Ethernet device (the DHCP server) for the necessary IP information, and then relays the assigned information back to the computer.
