server-vlan <idx>
Configures a VLAN ID for the DHCP scope.
To use this subnet, ensure that the VLAN ID
specified here is assigned to an SSID profile.
1-4093
—
subnet <subnet>
Defines the network IP address
—
—
subnet-mask <sub-
net_ mask>
Defines the subnet mask for Local, Local,
L3, and distributed, l3 DHCP scopes. The
subnet mask and the network determine the
size of subnet.
—
—
vlan-ip <VLAN_IP>
mask <VLAN mask>
Defines the IP address and subnet mask for
the DHCP server VLAN for Local, Local, L3,
and Centralized, L3 servers.

Usage Guidelines
Use this command to configure the DHCP address assignment for the branches connected
to the corporate network through VPN. You can configure the following types of DHCP
profiles.
●
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.
●
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.
●
Local — In this mode, the Virtual Controller acts as both the DHCP Server and the default
gateway. The configured subnet and the corresponding DHCP scope are independent of
subnets configured in other AP clusters. The Virtual Controller assigns an IP address
from a local subnet and forwards traffic to both corporate and non-corporate destinations.
The network address is translated appropriately and the packet is forwarded through the
IPSec tunnel or through the uplink. This DHCP assignment mode is used for the NAT
forwarding mode.
