•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.

•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.

TYPE

Select any of the following options:

 

• 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.

 

• Local, L3—On selecting Local, L3, the Virtual Controller acts as a DHCP server

 

and gateway.

 

 

VLAN

Specifies a VLAN ID. To use this subnet, ensure that the VLAN ID specified here is

 

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.

 

 

LEASE TIME

Specifies a lease time for the client in minutes.

 

 

OPTION
