Table 45: Centralized DHCP Mode Configuration Parameters 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 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 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. 4.

Parameter

Description

Name

Enter a name for the DHCP scope.

Type

Set the type as follows:

Centralized, L2

for the Centralized, L2 profile

Centralized, L3

for the Centralized, L3 profile

VLAN

Specify 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 83

and

Configuring VLAN for a Wired

Profile on page 105

Split tunnel

Set this to

Enabled

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:

Remote Circuit ID; X AP-MAC; SSID; SSID-Type

Remote Agent; X IDUE-MAC

NOTE:

The Option 82 string is specific to Alcatel and is not configurable.
