The traffic flow is as follows:
1. A client sends DHCP discover broadcast.
2. The AP tunnels this DHCP discover frame to the controller.
3. The DHCP relay agent sends unicast DHCP discover packet to the DHCP server.
4. The DHCP server sends DHCP offer to the relay agent on the controller.
5. The controller sends DHCP offer back to the AP.
6. The AP sends this DHCP offer to the client.
By reducing broadcast flooding, this option allows for higher client capacity in tunneled WLANs
designed for VoIP phones, for example. It also allows for DHCP discovery across multiple subnets
and limits DHCP broadcasts to client’s AP tunnel and radio.
