Configuring Centralized DHCP Scopes
When a centralized DHCP scope is configured, the following points are to be noted:
l The VC 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 VC 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 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.
