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. To configure a centralized DHCP scopes, click New under Centralized DHCP Scopes. The New DHCP Scope window is displayed. 3. To configure centralized,L2 profile, select the profile type as Centralized,L2 or Centralized,L3 and configure the following parameters. 220 | DHCP Configuration Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | User Guide

Configuring Centralized DHCP Scopes
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 Centralized, L2 clients, the Virtual Controller bridges the DHCP traffic to the controller over the VPN/GRE
tunnel. 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

1. Click

DHCP Server
window is displayed.
2. To configure a centralized DHCP scopes, click

window is displayed.
3. To configure centralized,L2 profile, select the profile type as
Centralized,L2
or
Centralized,L3
and
configure the following parameters.
