40.4 DHCPv4 Relay

Configure DHCP relay on the Switch if the DHCP clients and the DHCP server are not in the same
broadcast domain. 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.
