This command is used to configure DHCP relay functions for host devices
attached to the switch. If DHCP relay service is enabled, and this switch
sees a DHCP request broadcast, it inserts its own IP address into the
request so the DHCP server will know the subnet where the client is
located. Then, the switch forwards the packet to the DHCP server on
another network. When the server receives the DHCP request, it allocates a
free IP address for the DHCP client from its defined scope for the DHCP
client’s subnet, and sends a DHCP response back to the DHCP relay agent
(i.e., this switch). This switch then broadcasts the DHCP response received
from the server to the client.
