109 Chapter 7 Wireless Security
Authentication
Method
This field is activated when you select 64-bit WEP or 128-bit WEP in the WEP
Encryption field. Select Auto, Open System or Shared Key from the drop-down
list box.
ASCII Select this option in order to enter ASCII characters as the WEP keys.
Hex Select this option in order to enter hexadecimal characters as the WEP keys.
The preceding "0x", that identifies a hexadecimal key, is entered automatically.
Key 1 to Key 4 The WEP keys are used to encrypt data. Both the ZyAIR and the wireless
stations must use the same WEP key for data transmission.
If you chose
64-bit WEP , then enter any 5 ASCII characters or 10 hexadecimal
characters ("0-9", "A-F").
If you chose
128-bit WEP , then enter 13 ASCII characters or 26 hexadecimal
characters ("0-9", "A-F").
You must configure all four keys, but only one key can be activated at any one
time. The default key is key 1.
ReAuthentication
Timer (in seconds)
Specify how often wireless stations have to reenter usernames and passwords
in order to stay connected. Enter a time interval between 10 and 9999 seconds.
The default time interval is 1800 seconds (30 minutes).
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server has
priority.
Idle Timeout The ZyAIR automatically disconnects a wireless station from the wired network
after a period of inactivity. The wireless station needs to enter the username and
password again before access to the wired network is allowed. The default time
interval is 3600 seconds (or 1 hour).
Authentication
Databases
The authentication database contains wireless station login information. The
trusted user database is the built-in database on the ZyAIR. The RADIUS is an
external server. Use this drop-down list box to select which database the ZyAIR
should use (first) to authenticate a wireless station.
Before you specify the priority, make sure you have set up the corresponding
database correctly first.
Select
Local User Database Only to have the ZyAIR just check the built-in user
trusted user database on the ZyAIR for a wireless station's username and
password.
Select
RADIUS Only to have the ZyAIR just check the user database on the
specified RADIUS server for a wireless station's username and password.
Select
Local first, then RADIUS to have the ZyAIR first check the trusted user
database on the ZyAIR for a wireless station's username and password. If the
user name is not found, the ZyAIR then checks the user database on the
specified RADIUS server.
Select
RADIUS first, then Local to have the ZyAIR first check the user
database on the specified RADIUS server for a wireless station's username and
password. If the ZyAIR cannot reach the RADIUS server, the ZyAIR then checks
the trusted user database on the ZyAIR. When the user name is not found or
password does not match in the RADIUS server, the ZyAIR will not check the
trusted user database and the authentication fails.
