Wireless protection
Two types of wireless protection are offered. WPA and WEP.
On the MSM410 and MSM422
When using 802.11n, wireless protection settings are enforced as follows:
WEP protection is never permitted. If selected, WPA or WPA2 protection is used instead.
When using pure 802.11n in either the 2.4 or 5 GHz bands, WPA2 protection is used
instead of WPA.
On the E-MSM430, E-MSM460, and E-MSM466
When using 802.11n, wireless protection settings are enforced as follows:
WEP protection is permitted. If selected, all 802.11n features of the radio are disabled for
this VSC. The VSC will only support legacy a/b/g traffic.
WPA is not supported on these products.
WPA
This option enables support for users with WPA / WPA2 client software.
Mode
Support is provided for:
WPA (TKIP): WPA with TKIP encryption. (Not supported on the E-MSM430, E-MSM460,
E-MSM466.)
WPA2 (AES/CCMP): WPA2 (802.11i) with AES/CCMP encryption.
WPA or WPA2: Mixed mode supports both WPA (version 1) and WPA2 (version 2) at the
same time.
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.
