Broadcast Key
Rotation
Select the Broadcast Key Rotation checkbox to enable or disable
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 option is disabled
by default.
Update broadcast
keys every (300-
604800 seconds)
Specify a time period in seconds for broadcasting encryption key
changes to MUs. Set key broadcasts to a shorter interval (at least
30 seconds) for tighter security on the WLAN's wireless
connections. Set key broadcasts to a longer interval to extend the
key times for wireless connections. Default is 86,400 seconds.
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
AP-5131 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-TKIP
clients
WPA2-CCMP Mixed Mode enables WPA2-CCMP and WPA-TKIP
clients to operate together on the network. Enabling this option
allows backwards compatibility for clients that support WPA-TKIP
but do not support WPA2-CCMP. Symbol recommends enabling this
feature if WPA-TKIP supported MUs operate within a WLAN
populated by WPA2-CCMP enabled clients.
