Chapter 8 AP Profile

8.3 SSID
The SSID screens allow you to configure three different types of profiles for your networked APs: an
SSID list, which can assign specific SSID configurations to your APs; a security list, which can
assign specific encryption methods to the APs when allowing wireless clients to connect to them;
and a MAC filter list, which can limit connections to an AP based on wireless clients MAC addresses.
8.3.1 SSID List
This screen allows you to create and manage SSID configurations that can be used by the APs. An
SSID, or Service Set IDentifier, is basically the name of the wireless network to which a wireless
DTIM Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Active Power Management
mode. A high DTIM value can cause clients to lose connectivity with the network. This
value can be set from 1 to 255.
Enable Signal
Threshold
Select the check box to use the signal threshold to ensure wireless clients receive good
throughput. This allows only wireless clients with a strong signal to connect to the AP.
Clear the check box to not require wireless clients to have a minimum signal strength
to connect to the AP.
Station Signal
Threshold
Set a minimum client signal strength. A wireless client is allowed to connect to the AP
only when its signal strength is stronger than the specified threshold.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Disassociate
Station
Threshold
Set a minimum kick-off signal strength. When a wireless client’s signal strength is
lower than the specified threshold, the NWA/WAC disconnects the wireless client from
the AP.
-20 dBm is the strongest signal you can require and -90 is the weakest.
Allow Station
Connection after
Multiple Retries
Select this option to allow a wireless client to try to associate with the AP again after it
is disconnected due to weak signal strength.
Station Retry
Count
Set the maximum number of times a wireless client can attempt to re-connect to the
AP
Multicast Settings
Transmission
Mode
Specify how the NWA/WAC handles wireless multicast traffic.
Select Multicast to Unicast to broadcast wireless multicast traffic to all of the wireless
clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the
application’s bandwidth requirements. The retransmit mechanism of unicast traffic
provides more reliable transmission of the multicast traffic, although it also produces
duplicate packets.
Select Fixed Multicast Rate to send multicast traffic to all wireless clients at a single
data rate. You must know the multicast application’s bandwidth requirements and set it
in the following field.
Multicast
Rate(Mbps)
If you set Transmission Mode to Fixed Multicast Rate, select a data rate at which
the NWA/WAC transmits multicast packets to wireless clients. For example, to deploy 4
Mbps video, select a fixed multicast rate higher than 4 Mbps.
OK Click OK to save your changes back to the NWA/WAC.
Cancel Click Cancel to exit this screen without saving your changes.
