Default level 2: System level Parameters None Description Use dhcp select relay to enable the relay agent on the current interface. Upon receiving requests from an enabled interface, the relay agent will forward these requests to outside DHCP servers for IP address allocation. Use undo dhcp select relay to restore the default. By default, DHCP relay agent is disabled.
