Dynamic Host Configuration Protocol (DHCP) Relay

DHCP Relay is an option used to have local hosts communicate to a DHCP server in another network and switch works as a relay device.

To activate the DHCP Relay

1. Navigate to Policies > Policy Hierarchy > Switch Policy.
2. Select the System tab and scroll down to the DHCP Relay section.
3. Enable the toggle bar, DHCP Relay Enable.
4. Click on Add DHCP Relay Server.
5. Specify the IP Address of the DHCP Relay Server.
6. Enable the toggle bar Mac Verify. If the device receives a packet on an untrusted interface and the source MAC address and the DHCP client hardware address do not match, address verification causes the device to drop the packet, if you enable this option.
