Use the IP Service > DHCP > Relay page to configue DHCP relay service for attached host devices. If DHCP relay is enabled, and this switch sees a DHCP request broadcast, it inserts its own IP address into the request so that the DHCP server will know the subnet where the client is located. Then, the switch forwards the packet to the DHCP server. When the server receives the DHCP request, it allocates a free IP address for the DHCP client from its defined scope for the DHCP client's subnet, and sends a DHCP response back to the DHCP relay agent (i.e., this switch). This switch then broadcasts the DHCP response received from the server to the client.
Command Usage
You must specify the IP address for at least one active DHCP server. Otherwise, the switch's DHCP relay agent will not be able to forward client requests to a DHCP server.
DHCP relay configuration will be disabled if an active DHCP server is detected on the same network segment.
Command Parameters
ID of configured VLAN.
Addresses of DHCP servers or relay servers to be used by the switch's DHCP relay agent in order of preference.
