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.

WPA2

This field is available only when you select WPA2.

Pre-authentication enables fast roaming by allowing the wireless client

(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

Interval

This field is available only when you select WPA2.

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

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.

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.
