5.4.3  MAC Filter
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address 
is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 
00:A0:C5:00:00:02. You need to know the MAC addresses of the devices to configure this 
screen. To change your device’s MAC filter settings, select a device and then click Device 
Operation > Device Configuration > Network > Wireless Card 
MAC Filter. The screen 
appears as shown.
Idle Timeout 
(Seconds)
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.
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.
Authentication 
Databases 
Click Local User to go to the Local User Database screen where you can view 
and/or edit the list of users and passwords. Click RADIUS to go to the RADIUS 
screen where you can configure the Vantage CNM to check an external RADIUS 
server.

DESCRIPTION
Security
Select No Access 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.
