Notice:
When a DHCP request packet comes, the DHCP relay receives it and then sends it to all VLANs. But
according to RFC 2131, when a unicast DHCP request packet renews, it will be sent to a DHCP
server directly without passing a DHCP relay, so it is recommended to make sure that the DHCP client
can ping the server after getting an IP address.

DHCP Relay Configuration
The DHCP relay sends a unicast DHCP packet to the specified server(s). The maximum number of
specified servers is 5. You can enable or disable a DHCP relay function, and configure the parameters of
the circuit ID sub-option (the interface ID on the switch which connects to the host) and the remote ID
sub-option (the MAC address of the host which sends DHCP request) on this page.

Remote ID Sub-Option
Enter a remote ID string (the MAC address of the host which sends the DHCP
request) for the circuit ID mode. This is a local identifier of the circuit from which a
DHCP client-to-server packet is received. It ensures that the DHCP relay sends
DHCP server responses back to the correct circuit.
