Chapter 5 Device Network Settings Table 36 Wireless Card: 802.1x + Dynamic WEP LABEL DESCRIPTION Security Select 802.1x + Dynamic WEP from the drop-down list. ReAuthenticati Specify how often wireless stations have to resend user names and on Timer passwords in order to stay connected. Enter a time interval between 10 (Seconds) and 65535 seconds. Idle Timeout (Seconds) If wireless station authentication is done using a RADIUS server, the reauthentication timer on the RADIUS server has priority. The Vantage CNM automatically disconnects a wireless station from the wireless network after a period of inactivity. The wireless station needs to send the username and password again before it can use the wireless network again. Some wireless clients may prompt users for a username and password; other clients may use saved login credentials. In either case, there is usually a short delay while the wireless client logs in to the wireless network again. Authentication Databases Dynamic WEP Key Exchange This value is usually smaller when the wireless network is keeping track of how much time each wireless station is connected to the wireless network (for example, using an authentication server). If the wireless network is not keeping track of this information, you can usually set this value higher to reduce the number of delays caused by logging in again. Click RADIUS to go to the RADIUS screen where you can configure the Vantage CNM to check an external RADIUS server. Select 64-bit WEP or 128-bit WEP to enable data encryption. Table 37 Wireless Card: 802.1x + Static WEP LABEL DESCRIPTION Security Select 802.1x + Static WEP from the drop-down list. WEP Encryption WEP (Wired Equivalent Privacy) provides data encryption to prevent unauthorized wireless stations from accessing data transmitted over the wireless network. Select 64-bit WEP or 128-bit WEP to enable data encryption. Key 1 to Key 4 If you chose 64-bit WEP in the WEP Encryption field, then enter any 5 characters (ASCII string) or 10 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key. If you chose 128-bit WEP in the WEP Encryption field, then enter 13 characters (ASCII string) or 26 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key. There are four data encryption keys to secure your data from eavesdropping by unauthorized wireless users. The values for the keys must be set up exactly the same on the access points as they are on the wireless stations. Vantage CNM User's Guide 119
