Setting Security Parameters
Enabling WPA/WPA2 Passphrase
Follow the steps below to enable WPA/WPA2 passphrase (also known as WPA/WPA2 pre-shared key) for
this profile.
Note To use WPA passphrase, access points must use Cisco IOS Release 12.2(11)JA or later. To use WPA2
passphrase, access points must use Cisco IOS Release 12.3(2)JA or later.
Step 1 Choose WPA/WPA2 Passphrase on the Profile Management (Security) window.
Step 2 Click Configure. The Define WPA/WPA2 Pre-Shared Key window appears (see Figure 5-6).
Figure 5-6 Define WPA/WPA2 Pre-Shared Key Window
Step 3 Obtain the WPA/WPA2 passphrase for the access point (in an infrastructure network) or other clients (in
an ad hoc network) from your system administrator and enter it in the WPA/WPA2 passphrase field.
Follow the guidelines below to enter a passphrase:
• WPA/WPA2 passphrases must contain 8 to 63 ASCII text characters or 64 hexadecimal characters.
• Your client adapter’s WPA/WPA2 passphrase must match the passphrase used by the access point
with which you are planning to communicate.
Step 4 Click OK to save the passphrase and return to the Profile Management (Security) window.
Step 5 If you want to change the value of the Group Policy Delay parameter, enter a new value or use the up
and down arrows to select a value between 0 and 65535 seconds. (Microsoft supports only values
between 30 and 600 seconds. The default value is 60 seconds.)
The Group Policy Delay parameter specifies how much time elapses before the Windows logon process
starts Group Policy, a Windows feature used by administrators to specify configuration options for
groups of users. The objective is to delay the start of Group Policy until wireless network authentication
occurs. The value that you set for this parameter goes into effect after the computer reboots with this
profile set as the active profile.
Note A Microsoft hot fix is required in order to use this parameter on computers running Windows
2000. Refer to the “Installing a Microsoft Hot Fix for Group Policy Delay” on page 3-21 for
information on obtaining and installing the hot fix.
Step 6 Click OK to save your settings and return to the Cisco Aironet Desktop Utility (Profile Management)
window.
