   WLAN Services Privacy Tab - Fields and Buttons

   Field/Button	Description
   None	Select to configure a WLAN service with no privacy settings.
   Static Keys (WEP)	Select to configure static key (WEP) privacy settings.
   WEP Key Index	From the WEP Key Index drop-down list, select the WEP encryption key index. Options are 1 to 4. This field is available only when configuring static keys.
   WEP Key Length	From the WEP Key Length drop-down list, click the WEP encryption key length. Options are: 64-bit, 128-bit, and 152-bit. This field is available only when configuring static keys.
   Input Method	Select one of the following input methods: Input Hex — If you select Input Hex, type the WEP key input in the WEP Key box. The key is generated automatically, based on the input. Input String — If you select Input String, type the secret WEP key string used for encrypting and decrypting in the Strings box. The WEP Key box is automatically filled by the corresponding Hex code. This field is available only when configuring static keys.
   WEP Key	Type the WEP key using the input method chosen above.
   Dynamic Keys (WEP)	Select to configure dynamic keys (WEP) privacy settings.
   WPA	Select to configure WPA privacy settings.
   WPA - PSK	Select to configure dynamic keys (WEP) privacy settings.
   WPA v.1	Select the checkbox to enable WPA v.1 encryption, and then select an encryption method: Auto — If you click Auto, the AP advertises both TKIP and CCMP (counter mode with cipher block chaining message authentication code protocol). CCMP is an IEEE 802.11i encryption protocol that uses the encryption cipher AES (Advanced Encryption Standard). Auto is the default. TKIP only — If you click TKIP, the AP advertises TKIP as an available encryption protocol. It will not advertise CCMP. This field is available only when configuring WPA and WPA - PSK privacy settings. Note: TKIP is no longer a supported configuration. Instead you will be directed to configure WPA/WPA2 mixed mode security.
   WPA v.2	Select the checkbox to enable WPA v.2 encryption, and then select an encryption method: Auto — If you click Auto, the AP advertises both TKIP and CCMP (counter mode with cipher block chaining message authentication code protocol). CCMP is an IEEE 802.11i encryption protocol that uses the encryption cipher AES (Advanced Encryption Standard). Auto is the default. AES only — If you click AES, the AP advertises CCMP as an available encryption protocol. It will not advertise TKIP. This field is available only when configuring WPA and WPA - PSK privacy settings. TKIP — If you click AES, the wireless AP advertises CCMP as an available encryption protocol.
   Key Management Options	Click one of the following key management options: None — The mobile units (client devices) perform a complete 802.1x authentication each time they associate or connect to an AP. Opportunistic Keying — Enables secure fast roaming (SFR) of mobile units. For more information, see Configuring WLAN Service Privacy. Pre-authentication — Enables seamless roaming. For more information, see Configuring WLAN Service Privacy. Opportunistic Keying & Pre-auth — For more information, see Configuring WLAN Service Privacy.
   Broadcast re-key interval	To enable re-keying after a time interval, select the Broadcast re-key interval box, then type the time interval after which the broadcast encryption key is changed automatically. The default is 3600 seconds. If this checkbox is not selected, the Broadcast encryption key is never changed and the AP will always use the same broadcast key for Broadcast/Multicast transmissions which will reduce the level of security for wireless communications.
   Management Frame Protection	Select to enable or disable frame protection for WPA v.2 privacy.
   Fast Transition	Click to Enable for 11r enabled APs. This feature only applies to 37xx and 38xx APs.
   Input Method	Select one of the following input methods: Input Hex — If you select Input Hex, type the pre-shared key as hex characters. Input String — If you select Input String, type the pre-shared key as a string of characters.
   Pre-shared key String	In the Pre-Shared Key box, type the shared secret key to be used between the wireless device and AP. The shared secret key is used to generate the 256-bit key. To proofread your entry before saving the configuration, click Unmask to display the Pre-Shared Key. To mask the key, click Mask
   Save	Click to save the configuration.
