6.11 Configuring privacy for a VNS
Privacy is a mechanism that protects data over wireless and wired networks,
usually by encryption techniques. The following section describes how the
Privacy mechanism is handled for a Captive Portal VNS and an AAA VNS.
6.11.1 Privacy for a VNS for Captive Portal
For the Captive Portal VNS, there are three options for the privacy mechanism:
•None
• Static Wired Equivalent Privacy (WEP) – Keys for a selected VNS, so that
it matches the WEP mechanism used on the rest of the network. Each radio
can support up to eight SSIDs (16 SSIDs per AP). Each AP can participate in
up to 50 VNSs. For each VNS, only one WEP key can be specified. It is
treated as the first key in a list of WEP keys.
• Wi-Fi Protected Access (WPA) Pre-Shared key (PSK) – Privacy in PSK
mode, using a Pre-Shared Key (PSK), or shared secret for authentication.
WPA-PSK is a security solution that adds authentication to enhanced WEP
encryption and key management. WPA-PSK mode does not require an
authentication server. It is suitable for home or small office.
Wireless 802.11n APs and WPA authentication
If a VNS is configured to use WPA authentication, any Wireless 802.11n AP within
that VNS will do the following:
• WPA v.1 – If WPA v.1 is enabled, the Wireless 802.11n AP will advertise only
TKIP as an available encryption protocol.
• WPA v.2 – If WPA v.2 is enabled, the Wireless 802.11n AP will do the
following:
• If WPA v.1 is enabled, the Wireless 802.11n AP will advertise TKIP as an
available encryption protocol.
• If WPA v.1 is disabled, the Wireless 802.11n AP will advertise the
encryption cipher AES (Advanced Encryption Standard).
To configure privacy by static WEP for a Captive Portal VNS:
1. From the main menu, click Virtual Network Configuration. The Virtual
Network Configuration page is displayed.
2. In the left pane Virtual Networks list, click the VNS you want to configure
privacy by static WEP for a Captive Portal. The Topology tab is displayed.
3. Click the Privacy tab.
4. Select Static Keys (WEP).
