37.4 DHC Pv4 Re la y
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.
