WPA2

This field is available only when you select WPA2.

Preauthenticatio

Pre-authentication enables fast roaming by allowing the wireless client

n

(already connecting to an AP) to perform IEEE 802.1x authentication

 

 

with another AP before connecting to it. Select Enabled to turn on

 

preauthentication in WAP2. Otherwise, select Disabled.

 

 

Network Re-auth

This field is available only when you select WPA2.

Interval

Specify how often wireless clients have to resend usernames and

 

 

passwords in order to stay connected. Enter a time interval between

 

10 and 2147483647 seconds.

 

Note: If wireless client authentication is done using a RADIUS

 

server, the reauthentication timer on the RADIUS server has

 

priority.

 

 

Group Key

The Group Key Update Timer is the rate at which the RADIUS server

Update Timer

sends a new group key out to all clients.

 

Authentication Server

 

 

IP Address

Enter the IP address of the external authentication server in dotted

 

decimal notation.

 

 

Port Number

Enter the port number of the external authentication server. The

 

default port number is 1812.

 

You need not change this value unless your network administrator

 

instructs you to do so with additional information.

 

 

Shared Secret

Enter a password (up to 31 alphanumeric characters) as the key to be

 

shared between the external authentication server and the P-

 

2812HNU-51c.

 

The key must be the same on the external authentication server and

 

your P-2812HNU-51c. The key is not sent over the network.

 

 

7.4.5 MAC Filter

This screen allows you to configure the P-2812HNU-51c to give exclusive access to specific devices (Allow) or exclude specific devices from accessing the P- 2812HNU-51c (Deny). Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. You need to know the MAC addresses of the devices to configure this screen.
