6.
Configure the
Key Settings
area as needed to set an ASCII Passphrase and 128-bit key.
Default (hexadecimal) 256-bit keys for WP2A/CCMP include:

7.
Configure the
WPA2-CCMP Mixed Mode
field as needed to allow WPA and WPA2 TKIP
client interoperation.
8.
Configure the
Fast Roaming (802.1x only)
field as required to enable additional access
point roaming and key caching options. This feature is applicable only when using 802.1x
EAP authentication with WPA2/CCMP.
ASCII Passphrase
To use an ASCII passphrase (and not a hexadecimal value), select
the checkbox enter an alphanumeric string of 8 to 63 characters.
The string allows character spaces. The
access point
converts the
string to a numeric value. This passphrase saves the administrator
from entering the 256-bit key each time keys are generated.
256-bit Key
To use a hexadecimal value (and not an ASCII passphrase), select
the checkbox and enter 16 hexadecimal characters into each of the
four fields displayed.
Allow
WPA/WPA2-TKIP
clients
WPA2-CCMP Mixed Mode enables WPA2-CCMP, WPA-TKIP and
WPA2-TKIP clients to operate together on the network. Enabling
this option allows backwards compatibility for clients that support
WPA-TKIP and WPA2-TKIP but do not support WPA2-CCMP.
Motorola recommends enabling this feature if WPA-TKIP or
WPA2-TKIP supported MUs operate within a WLAN populated by
WPA2-CCMP enabled clients.
Pre-Authentication
Selecting this option enables an associated MU to carry out an
802.1x authentication with another access point before it roams to
it. The access point caches the keying information of the client until
it roams to the other access point. This enables the roaming client
to start sending and receiving data sooner by not having to do
802.1x authentication after it roams. This feature is only supported
when 802.1x EAP authentication is enabled.
