VSC configuration options
Key source
This option determines how the TKIP keys are generated.
Dynamic: This is a dynamic key that changes each time the user logs in and is
authenticated. The MPPE key is used to generate the TKIP keys that encrypt the wireless
data stream. The key is generated via the configured 802.1X authentication method.
Therefore, when you enable this option, the 802.1X authentication feature is
automatically enabled.
Authentication can occur via the local user accounts and remote authentication server
(Active Directory, or third-party RADIUS server). If both options are enabled, the local
accounts are checked first.
Preshared Key: The service controller uses the key you specify in the Key field to
generate the TKIP keys that encrypt the wireless data stream. Since this is a static key, it
is not as secure as the RADIUS option. Specify a key that is between 8 and 63
alphanumeric characters in length. It is recommended that the preshared key be at least
20 characters long, and be a mix of letters and numbers. The double quote character (”)
should not be used.
Terminate WPA at the service controller
Note This feature is intended for low-data-volume applications like that of wireless POS terminals.
This option controls the termination of WPA/WPA2 client sessions.
