A DHCP server provides an address, from a defined address range, to a client on the network that requests it.
You can configure one or more DHCP servers on any FortiSwitch interface. A DHCP server dynamically assigns IP addresses to hosts on the network connected to the interface. The host computers must be configured to obtain their IP addresses using DHCP.
You can configure a FortiSwitch interface as a DHCP relay. The interface forwards DHCP requests from DHCP clients to an external DHCP server and returns the responses to the DHCP clients. The DHCP server must have the appropriate routing so that its response packets to the DHCP clients arrive at the unit.
