Configuring Centralized DHCP Scope

The Centralized DHCP scope supports L2 and L3 clients.

When a centralized DHCP scope is configured:

l The Virtual Controller does not assign an IP address to the client and the DHCP traffic is directly forwarded to the

DHCP Server.

l For L2 clients, the Virtual Controller bridges the DHCP traffic to the switch over the VPN/GRE tunnel. The IP

address is obtained from the DHCP server behind the switch serving the VLAN/GRE of the client. This DHCP

assignment mode also allows you to add the DHCP option 82 to the DHCP traffic forwarded to the controller.

l For L3 clients, the Virtual Controller acts as a DHCP relay agent that forwards the DHCP traffic to the DHCP

server located behind the switch in the corporate network and reachable through the IPSec tunnel. The

centralized L3 VLAN IP is used as the source IP. The IP address is obtained from the DHCP server.

You can configure Centralized DHCP scope by using the AOS-W Instant UI or CLI.

1. Click More>DHCP Server. The DHCP Server window is displayed.
