30.4 DHCP Relay
Configure DHCP relay on the switch if the DHCP clients and the DHCP server are not in the
same subnet. During the initial IP address leasing, the switch helps to relay network
information (such as the IP address and subnet mask) between a DHCP client and a DHCP
server. Once the DHCP client obtains an IP address and can connect to the network, network
information renewal is done between the DHCP client and the DHCP server without the help
of the switch.
