Beacon
Select whether or not to send beacons for this network.
Beacons identify this network to other devices with several types of informa-
tion, such as the BSSID (MAC address) of the wireless radio sending the bea-
con and the SSID name (Broadcast SSID) that clients see in there list of
available wireless networks.
•
If "Yes" is selected, the beacon is sent on a regular basis so clients can
detect it and request an association with that network. The SSID name
may or may not be "advertised" in the client’s available networks list,
depending on the Broadcast SSID setting. If this network is listed first in
the client’s list of preferred networks, the client will automatically attempt to
associate with this network when it sees this beacon.
•
If "No" is selected, the beacon for this network is not sent. In this case, cli-
ents must initiate the association to the network by sending a probe
request that contains the SSID to which it is trying to connect. Some cli-
ents may not have this capability, and therefore will not operate in a net-
work where beacons are not being sent.
Broadcast SSID
If beacons are enabled, you can select whether or not to sent the SSID’s name
in the beacon to "advertise" itself to wireless clients.
•
If "Yes" is selected, clients will see the SSID name in their list of available
wireless networks.
•
If "No" is selected, clients will not see the SSID name in their list of avail-
able wireless networks. In this case, the SSID name must be manually
entered into the client’s configuration before it can access the network.
DTIM Period
The
Delivery Traffic Information Map
(DTIM) message is an element included
in some Beacon frames. It indicates which client stations, currently sleeping in
low-power mode, have data buffered on the AP/Bridge awaiting pick-up.
The DTIM you specify here indicates how often the clients served by this AP/
Bridge should check for buffered data still on the VA4200 awaiting pickup.
Specify a DTIM in the range of 1 - 255.
The measurement is in beacons. For example, if you set this to "1" clients will
check for buffered data on the VA4200 at every beacon. If you set this to "2",
clients will check on every other beacon. If you set this to 10, clients will check
on every 10th beacon.
Security Mode
Select the type of wireless security to use with this network. See “Configuring
Security Settings” on page 97 for a description of each security mode, includ-
ing the configuration of an external RADIUS authentication and accounting
server.
