Broadcast Key
Rotation Select the Broadcast Key Rotation checkbox to enable or disable broadcast key
rotation. When enabled, the key indices used for encrypting/decrypting broadcast traffic
will be alternatively rotated on every interval specified in the Broadcast Key Rotation
Interval. Enabling broadcast key rotation enhances the broadcast traffic security on the
WLAN. This value is disabled by default.
Update broadcast keys
every (300-604800
seconds) Specify a time period in seconds to rotate the key index used for the broadcast key. Set the
interval to a shorter duration like 3600 seconds for tighter broadcast traffic security on the
wireless LAN. Set the interval to a longer duration like 86400 seconds for less broadcast
traffic security requirements. Default value is 86400 secs.
ASCII Passphrase To use an ASCII passphrase (and not a hexadecimal value), select the checkbox and enter
an alphanumeric string of 8 to 63 characters. The alphanumeric string allows character
spaces. The Mobility 7131 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.
