Set key broadcasts to a shorter interval (at least 60 seconds) for tighter security on wireless
connections. Set key broadcasts to a longer interval (at most, 86400 seconds) to extend key
times for wireless connections. The default is 7200 seconds.
Configure the Key Settings field as needed to set an ASCII Passphrase and key values.
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 controller 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.
NOTE
The Web UI does not support saving passphrases in encrypted format. To save passphrases in
an encrypted format, configure the passphrases using the Command Line Interface. Refer to
the CLI Reference Guide for details on configuring passphrases using the CLI.
