126 | ip dhcp Dell Networking W-Series Instant 6.2.1.0-3.4 | CLI Reference Guide
Parameter Description Range Default
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.
l 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 W-IAP
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.
l Local, L3— In this mode, the
Virtual Controller acts as a DHCP
server and the gateway and
assigns an IP address from the
local subnet. The W-IAP routes
the packets sent by clients on its
uplink. This mode does not
provide corporate access
through the IPsec tunnel. This
DHCP assignment mode is used
with the L3 forwarding mode.
l Centralized, L2— In this mode,
the Virtual Controller does not
assign an IP address to the
client. However, the Virtual
Controller acts as DHCP Relay
that forwards the DHCP traffic to
the controller over the VPN
tunnel. The IP address is
obtained from either the
controller, or a DHCP server
behind the controller serving the
VLAN of the client. This DHCP
assignment mode also allows
you to add the DHCP option 82
to the DHCP traffic forwarded to
the controller.
server-vlan <VLAN-ID>
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.
