Parameter Description
Name
Enter a name for the DHCP scope.
Type
Set the type as follows:
l Centralized, L2 for the Centralized, L2 profile
l Centralized, L3 for the Centralized, L3 profile
VLAN
Specify a VLANID. To use this subnet, ensure that the VLANID 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 83 and Configuring VLAN for a Wired
Profile on page 105.
Split tunnel
Set this to Enabled or Disabled for split tunnel functionality for the Centralized, L2
subnet.
Enabling split tunnel allows a VPN user to access a public network and a local LAN or
WAN network at the same time through the same physical network connection. For
example, a user can use a remote access VPN software client connecting to a corporate
network using a home wireless network. The user with split tunneling enabled is able to
connect to file servers, database servers, mail servers, and other servers on the
corporate network through the VPN connection. When the user connects to Internet
resources (websites, FTP sites, and so on), the connection request goes directly to the
gateway provided by the home network. The split-DNS functionality intercepts DNS
requests from clients for non-corporate domains (as configured in Enterprise Domains
list) and forwards to the W-IAP's own DNS server.
When split-tunnel is disabled, all the traffic including the corporate and Internet traffic is
tunneled irrespective of the routing profile specifications. If the GRE tunnel is down and
when the corporate network is not reachable, the client traffic is dropped.
DHCP relay If you are configuring a Centralized, L2 DHCP profile, you can select Enabled to allow
the W-IAPs to intercept the broadcast packets and relay DHCP requests to the
centralized DHCP server.
NOTE: The DHCP relay option is not available for Centralized, L3 profile configuration.
Helper address Specify the IP address of the DHCP server.
NOTE: For Centralized, L2 DHCP profiles, the Helper address option is displayed only
when DHCP relay is enabled.
VLAN IP Specify the Centralized, L3 DHCP subnet gateway IP.
VLAN Mask Specify the subnet mask of the Centralized, L3 DHCP subnet gateway IP.
Option82
Select Alcatel to enable DHCP Option 82 and allow clients to send DHCP packets with
the Option 82 string. The Option 82 string is available only in the Alcatel (ALU) format.
The ALU format for the Option 82 string consists of the following:
l Remote Circuit ID; X AP-MAC; SSID; SSID-Type
l Remote Agent; X IDUE-MAC
NOTE: The Option 82 string is specific to Alcatel and is not configurable.
