DESCRIPTION
Security Mode
Select
WPA
or
WPA2
to enable data encryption.
WPA Compatible
This check box is available only when you select
WPA2-PSK
or
WPA2
in the
Security Mode
field.
Select the check box to have both WPA2 and WPA wireless clients be able to
communicate with the EMG6765-Q10A even when the EMG6765-Q10A is using WPA2-PSK
or WPA2.
Group Key Update
Timer
The
Group Key Update Timer
is the rate at which the AP (if using
WPA-PSK/WPA2-PSK
key
management) or RADIUS
server (if using
WPA/WPA2
key management) sends a new group
key out to all clients. The re-keying process is the WPA/WPA2 equivalent of automatically
changing the WEP key for an AP and all stations in a WLAN on a periodic basis. Setting of
the
Group Key Update Timer
is also supported in
WPA-PSK/WPA2-PSK
mode.
PMK Cache Period
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 999999 minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
Pre-Authentication
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
Enable
to turn on preauthentication in WAP2. Otherwise, select
Disable
.
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.
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 127 alphanumeric characters) as the key to be shared between
the external authentication server and the EMG6765-Q10A.
The key must be the same on the external authentication server and your EMG6765-Q10A.
The key is not sent over the network.
Session Timeout
The EMG6765-Q10A automatically disconnects a wireless client from the wireless and wired
networks after a period of inactivity. The wireless client needs to send the username and
password again before it can use the wireless and wired networks again. Some wireless
clients may prompt users for a username and password; other clients may use saved login
credentials. In either case, there is usually a short delay while the wireless client logs in to
the wireless network again.
Enter the time in seconds from 0 to 999999.
