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 VC 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 the CLI. In the Instant UI To configure a centralized DHCP scope: 1. Click More > DHCP Server. The DHCP Server window is displayed. 2. To configure a centralized DHCP scope, click New under Centralized DHCP Scopes. The New DHCP Scope window is displayed. 3. To configure a centralized profile, select the profile type as Centralized, L2 or Centralized, L3 and configure the following parameters. 212 | DHCP Configuration Dell Networking W-Series Instant 6.5.1.0-4.3.1.0 | User Guide
