Configuration Examples: WPA2-PSK and Open Authentication

The Configuration Examples: WPA2-PSK and Open Authentication document describes the benefits of using Wi-Fi Protected Access 2 (WPA2) in a Wireless LAN (WLAN). The document also provides the following configuration examples for implementing WPA2 on a WLAN:

  • Configuring WPA2 Pre-Shared Key (PSK)

  • Configuring Open Authentication

Prerequisites

We recommend that you have knowledge about the following topics:

  • Wireless Protected Access (WPA)

  • WLAN Security Solutions

Supported Platforms and Releases

The information in this document is based on the following software and hardware versions:

  • Cisco Aironet 3600 Series Lightweight Access Point

  • Microsoft Windows 7 native wireless supplicant


Note

The information in this document is based on the devices used in a specific lab environment. The devices used in this document started with a default configuration. If your network is live, make sure that you understand the potential impact of the commands.

WPA2 PSK and Open Authentication

The following figure displays the network diagram for WPA2 PSK and Open Authentication:

Figure 1. Network Diagram



Configuring WPA2-PSK Configuration using CLI

The following example describes the procedure to configure DHCP snooping for the VLANs that are used for the clients. In this example, VLAN20 is used for clients and the pool is configured on the same WLC.

TheTenGigabitEthernet1/0/1 interface is connected to the uplink switch. If the DHCP server is configured on the server apart from the WLC or an external DHCP server, you must trust the DHCP snooping and relay information.

Configuring WPA2-PSK Configuration using GUI

Perform the following steps to configure a WPA2 PSK on the WLC GUI:

    Step 1  

    To create a new WLAN, navigate to Configuration > Wireless > WLAN > WLANs.

    Figure 2. Wireless Controller Page



    Step 2  

    To enable WPA2, check the Status check box and then map WPA2 to the relevant interface.

    Figure 3. WLAN Page



    Step 3  

    Click the Security tab, check the WPA2 Policy check box and the AES check box. From the Auth Key Mgmt drop-down list, choose PSK and then enter the PSK value that the client needs to connect.

    Configuring Open Authentication using CLI

    The following example describes how to configure DHCP snooping for the VLANs that are used for clients. In the following example, VLAN20 is used for clients and the pool is configured on the same WLC.

    The TenGigabitEthernet1/0/1 interface is connected to the uplink switch. If you have the DHCP server configured on the server apart from the WLC or an external DHCP server, you must trust DHCP snooping and relay information.

    Configuring Open Authentication using GUI

    Perform the following steps to configure an open authentication in the WLC GUI:

      Step 1  
      To create a new WLAN navigate to Configuration > Wireless > WLAN > WLANs.
      Figure 5. Wireless Controller

      Step 2  
      Click the Security tab. Set the Layer2 tab and Layer3 tab to none. The following figure displays the configuration results:
      Figure 6. WLAN Page



      Verifying WPA2-PSK and Open Authentication Configuration

      Perform the following to verify the WPA2-PSK and Open Authentication configuration:

      Check and confirm that the WPA2-PSK client is connected as displayed in the following figure:
      Figure 7. WPA2-PSK Client Connection



      Check and confirm that the client is connected to Open Authentication as displayed in the following figure:
      Figure 8. Open Authentication Client Connection
