You can enable the Layer 3 DHCP relay agent on a routing interface and let the interface
relay DHCP messages between DHCP clients and DHCP servers that are located in a
different IP subnet.

To configure a DHCP relay interface:

1. Launch a web browser.

2. In the address field of your web browser, enter the IP address of the switch.

If you do not know the IP address of the switch, see Log in to the main UI with a web
browser on page 27 and the subsections.
