Delta DVS Series User Manual

DVS Series Managed Industrial Ethernet Switches User’s Manual
3. If the switch has configured an IP address, the IP address will be added into the DHCP packet.
4. If a DHCP server supports option-82, after the DHCP server receives the DHCP request, it will
allocate the IP address numbers according to the remote-ID sub-option or circuit ID sub-option.
5. A DHCP server responds to the switch via unicast. And the switch checks whether the
remote-ID or circuit-ID in option-82 matches the value of the DHCP request, and makes sure it
sends from the certificated DHCP server. Then it removes the information of option-82, and
sends back to the interface on the switch which sends the DHCP request.
