User's Manual

l Local — In this mode, the Virtual Controller acts as both the DHCP Server and 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.
l Local, L3 — In this mode, the Virtual Controller acts as a DHCP server and default gateway, and assigns an IP
address from the local subnet. The AP routes the packets sent by clients on its uplink. This DHCP assignment
mode is used with the L3 forwarding mode.
To configure a new DHCP scope:
1. Select Wireless Configuration > DHCP. The DHCP Server data pane is displayed.
2. To configure a Local or Local, L3 DHCP scope, click New at Local DHCP Scopes. The New DHCP Scope
pane is displayed.
3. Based on type of DHCP scope, configure the following parameters:
Data pane item Description
NAME Enter a name for the DHCP scope.
TYPE Select any of the following options:
l Local— On selecting Local, the DHCP server for local branch network is used for
keeping the scope of the subnet local to the AP. In the NAT mode, the traffic is
forwarded through the uplink.
l Local, L3—On selecting Local, L3, the Virtual Controller acts as a DHCP server
and gateway.
VLAN

assigned to an SSID profile. For more information on SSID profile configuration, see
Configuring VLAN settings for a WLAN SSID profile on page 26
NETWORK
Specifies the network to use.
NETMASK
Specifies the subnet mask. The subnet mask and the network determine the size of
subnet.
EXCLUDED ADDRESS
If
Local,L3
is selected, specify the IP address to exclude. The value entered in the
field determines the exclusion range of the subnet. Based on the size of the subnet,
the IP addresses that come before or after the IP address value specified in this field
are excluded.
DNS SERVER
Specifies the IP address of a DNS server for the
Local
and
Local,L3
scopes.
DOMAINNAME
Specifies the domain name for the
Local
and
Local,L3
scopes.
