WEC8050 / WEC8500 Operation Manual
5.4.2 DHCP Relay
The DHCP relay forwards a DHCP packet received from a client through broadcast to the
DHCP server. Because it switches with the DHCP proxy, the DHCP relay is enabled when
the DHCP proxy is disabled.
The DHCP relay is working in the unit of interface. It is disabled in the 'mgmt0' and 'lo'
interface. The DHCP relay is not working even when no IP address is configured in the
interface.
Configuration using CLI
The procedure of changing to the DHCP relay is as follows:
1) Go to the configure mode of the CLI.
WEC8500# configure terminal
2) Switch to the DHCP relay.
The relay and proxy are operating in the switching mode. If a proxy is not used, it is
operating in the relay mode.
WEC8500/configure # no ip dhcp-proxy enable
3) To check the configured DHCP information, use the 'show ip dhcp-proxy' command.
Configuration using Web UI
In the menu bar of <WEC Main window>, select <Configuration> and then select the
<DHCP>  <Proxy> menu in the sub-menus.
You can configure the Proxy mode of DHCP to relay/proxy. Change the radio box for
configuration in the DHCP PROXY MODE of Global Parameter item.
