The IP address is obtained from the DHCP server behind the controller 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 Centralized, L3 clients, the Virtual Controller acts as a DHCP relay agent that forwards the DHCP traffic to the DHCP server located either in the corporate or local network. The centralized L3 VLAN IP is used as the source IP. The IP address is obtained from the DHCP server. You can configure a centralized DHCP scope through the Instant UI or CLI. In the Instant UI To configure a centralized DHCP scope: 1. Click More > DHCP Server. The DHCP Server window is displayed. 2.
