Chapter 4 Configuring Controller SettingsWireless Device Access

Using the Configuration Wizard

Step 11 Enter the IP address of the management interface netmask.

Step 12 Enter the IP address of the default router.

Step 13 Enter the VLAN identifier of the management interface (either a valid VLAN identifier or 0 for an

untagged VLAN). The VLAN identifier should be set to match the switch interface configuration.

Step 14 Enter the network interface (distribution system) physical port number. For the controller, the possible

ports are 1 through 4 for a front panel GigE port.

Step 15 Enter the IP address of the default DHCP server that will supply IP addresses to clients, the management

interface, and the service port interface if you use one.

Step 16 Enter Layer2 or Layer3 for the LWAPP transport mode. Refer to Chapter 1 for more information on

Layer 2 and Layer 3 operation.

Note The controller in the Catalyst 3750G Integrated Wireless LAN Controller Switch operates only

in Layer 3 mode.

Step 17 Enter the IP address of the access point manager interface.

Step 18 Enter the IP address of the controller’s virtual interface. You should enter a fictitious, unassigned IP

address such as 1.1.1.1.

Note The virtual interface is used to support mobility management, DHCP relay, and embedded Layer

3 security such as guest web authentication and VPN termination. All controllers within a

mobility group must be configured with the same virtual interface IP address.

Step 19 If desired, enter the name of the mobility group/RF group to which you want the controller to belong.

Note Although the name that you enter here is assigned to both the mobility group and the RF group,

these groups are not identical. Both groups define clusters of controllers, but they have different

purposes. All of the controllers in an RF group are usually also in the same mobility group and

vice versa. However, a mobility group facilitates scalable, system-wide mobility and controller

redundancy while an RF group facilitates scalable, system-wide dynamic RF management. See

Chapter 10 and Chapter 11 for more information.

Step 20 Enable or disable symmetric mobility tunneling by entering yes or no. Symmetric mobility tunneling

allows inter-subnet mobility to continue when reverse path filtering (RPF) is enabled on a router on any

of the subnets. Refer to Chapter 11 for more information.

Step 21 Enter the network name, or service set identifier (SSID). The initial SSID enables basic functionality of

the controller and allows access points that have joined the controller to enable their radios.

Step 22 Enter yes to allow clients to assign their own IP address or no to require clients to request an IP address

from a DHCP server.

Step 23 To configure a RADIUS server now, enter yes and then enter the IP address, communication port, and

secret key of the RADIUS server. Otherwise, enter no. If you enter no, the following message appears:

“Warning! The default WLAN security policy requires a RADIUS server. Please see documentation for

more details.”
