5. Select the 

 checkbox to enable the broadcasting of encryption-key changes to 

MUs. 

Only broadcast key changes when required by associated MUs to reduce the transmissions of sensitive 
key information. This value is enabled by default.

6. Refer to the 

field to

specify a time period (in seconds) for broadcasting 

encryption-key changes to MUs. 

Set key broadcasts to a shorter time interval (at least 60 seconds) for tighter security on the WLAN's 
wireless connections. Set key broadcasts to a longer time interval (at most, 86400 seconds) to extend the 
key times for wireless connections. Default is 7200 seconds.

7. Configure the 

field as needed to set an ASCII Passphrase and key values.

Default (hexadecimal) 256-bit keys for WPA/TKIP include:

• 1011121314151617

• 18191A1B1C1D1E1F

• 2021222324252627

• 28292A2B2C2D2E2F

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 

switch

 converts the string to a numeric value. This passphrase saves the administrator 

from entering the 256-bit key each time keys are generated.

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.
