Chapter 4 Basic Wireless Device Configuration

Configuring Wireless Settings

Cisco IOS Command Line Interface

To configure the Autonomous wireless device, use the Cisco IOS CLI tool and perform these tasks:

•Configuring the Radio, page 4-5

•Configuring Wireless Security Settings, page 4-5

•Configuring Wireless Quality of Service, page 4-8(Optional)

Configuring the Radio

Configure the radio parameters on the wireless device to transmit signals in autonomous or Cisco Unified mode. For specific configuration procedures, see Chapter 9, “Configuring Radio Settings”.

Configuring Wireless Security Settings

•Configuring Authentication, page 4-5

•Configuring WEP and Cipher Suites, page 4-6

•Configuring Wireless VLANs, page 4-6

Configuring Authentication

Authentication types are tied to the Service Set Identifiers (SSIDs) that are configured for the access point. To serve different types of client devices with the same access point, configure multiple SSIDs.

Before a wireless client device can communicate on your network through the access point, the client device must authenticate to the access point by using open or shared-key authentication. For maximum security, client devices should also authenticate to your network using MAC address or Extensible Authentication Protocol (EAP) authentication. Both authentication types rely on an authentication server on your network.

To select an authentication type, see Authentication Types for Wireless Devices at: http://www.cisco.com/en/US/docs/routers/access/wireless/software/guide/SecurityAuthenticationTypes

.html.

To set up a maximum security environment, see RADIUS and TACACS+ Servers in a Wireless Environment at: http://www.cisco.com/en/US/docs/routers/access/wireless/software/guide/SecurityRadiusTacacs_1.htm l.

Configuring Access Point as Local Authenticator

To provide local authentication service or backup authentication service for a WAN link failure or a server failure, you can configure an access point to act as a local authentication server. The access point can authenticate up to 50 wireless client devices using Lightweight Extensible Authentication Protocol (LEAP), Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling (EAP-FAST), or MAC-based authentication. The access point performs up to 5 authentications per second.

You configure the local authenticator access point manually with client usernames and passwords because it does not synchronize its database with RADIUS servers. You can specify a VLAN and a list of SSIDs that a client is allowed to use.
