The following table describes the labels in this screen. 

PMK Cache

This field is available only when you select WPA2 or WPA2-MIX.
When a wireless client moves from one AP’s coverage area to another, it performs 

an authentication procedure (exchanging security information) with the new AP. 

Instead of re-authenticating a client each time it returns to the AP’s coverage area, 

which can cause delays to time-sensitive applications, the AP and the client can 

store (or “cache”) and use information about their previous authentication. 
Select Enable to allow PMK (Pairwise Master Key) caching, or Disable to switch 

this feature off.

Apply

Name

Type a name to identify this security profile.

Security Mode

Select WPA-PSK, WPA2-PSK or WPA2-PSK-MIX from the drop-down list.

Pre-Shared Key

The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The 

only difference between the two is that WPA(2)-PSK uses a simple common 

password, instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including 

spaces and symbols). 

ReAuthentication 

Timer 

Specify how often wireless clients have to resend user names and passwords in 

order to stay connected. Enter a time interval between 600 and 65535 seconds. 
If wireless client authentication is done using a RADIUS server, the 

reauthentication timer on the RADIUS server has priority.
