AOS-W Instant 6.3.1.1-4.0 | User Guide DHCP Configuration | 231
Chapter 21
DHCP Configuration
This chapter provides the following information:
l Configuring DHCP Scopes on page 231
l Configuring DHCP Server for Client IP Assignment on page 238
Configuring DHCP Scopes
The Virtual Controller supports different modes of DHCP address assignment. With each DHCP address
assignment mode, various client traffic forwarding modes are associated. For more information client traffic
forwarding modes for IAP-VPN, see L2/L3 Forwarding Modes on page 252.
You can configure Distributed,L2, Distributed,L3, Local or NAT DHCP, Local,L3, and Centralized L2 DHCP scopes
using the AOS-W Instant UI or CLI.
This section describes the following procedures:
l Configuring Distributed DHCP Scopes on page 231
l Configuring Centralized DHCP Scope on page 234
l Configuring Local and Local,L3 DHCP Scopes on page 236
Configuring Distributed DHCP Scopes
AOS-W Instant allows you to configure the DHCP address assignment for the branches connected to the corporate
network through VPN. You can configure the range of DHCP IP addresses used in the branches and the number of
client addresses allowed per branch. You can also specify the IP addresses that must be excluded from those
assigned to clients, so that they are assigned statically.
AOS-W Instant supports the following distributed DHCP scopes:
l Distributed, L2 — In this mode, the Virtual Controller acts as the DHCP server, but the default gateway is in the
data center. Based on the number of clients specified for each branch, the range of IP addresses is divided.
Based on the IP address range and client count configuration, the DHCP server in the Virtual Controller controls a
scope that is a subset of the complete IP Address range for the subnet distributed across all the branches. This
DHCP Assignment mode is used with the L2 forwarding mode.
l Distributed, L3 — In this mode, the Virtual Controller acts as the DHCP server and the default gateway. Based
on the number of clients specified for each branch, the range of IP addresses is divided. Based on the IP address
range and client count configuration, the DHCP server in the Virtual Controller is configured with a unique subnet
and a corresponding scope.
You can configure distributed DHCP scopes such as Distributed, L2 or Distributed,L3 by using the AOS-W Instant
UI or CLI.
In the AOS-W Instant UI
To configure distributed DHCP scopes such as Distributed,L2 or Distributed,L3:
1. Click More>DHCP. The DHCP Server window is displayed.
2. To configure a distributed DHCP mode, click New under Distributed DHCP Scopes. The New DHCP Scope
window is displayed. The following figure shows the contents of the New DHCP Scope window.
