6.4.1 Disassociating and Delaying Connections

When your AP becomes overloaded, there are two basic responses it can take. The first one is to
"delay" a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up
by another AP then the original AP cannot resume the connection.

DESCRIPTION
Select this to enable load balancing on the NWA/WAC.
Use this section to configure wireless network traffic load balancing between the
managd APs in this group.
Select a mode by which load balancing is carried out.
Select By Station Number to balance network traffic based on the number of specified
stations connected to the NWA/WAC.
Select By Traffic Level to balance network traffic based on the volume generated by
the stations connected to the NWA/WAC.
Select By Smart Classroom to balance network traffic based on the number of
specified stations connected to the NWA/WAC. The NWA/WAC ignores association
request and authentication request packets from any new station when the maximum
number of stations is reached.
If you select By Station Number or By Traffic Level, once the threshold is crossed
(either the maximum station numbers or with network traffic), the NWA/WAC delays
association request and authentication request packets from any new station that
attempts to make a connection. This allows the station to automatically attempt to
connect to another, less burdened AP if one is available.
Enter the threshold number of stations at which the NWA/WAC begins load balancing its
connections.
Select the threshold traffic level at which the NWA/WAC begins load balancing its
connections (Low, Medium, High).
This function is enabled by default and the disassociation priority is always Signal
Strength when you set Mode to By Smart Classroom.
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection
until it can afford the bandwidth it requires, or it transfers the connection to another AP
within its broadcast radius.
The disassociation priority is determined automatically by the NWA/WAC and is as
follows:
• Idle Timeout - Devices that have been idle the longest will be kicked first. If none
of the connected devices are idle, then the priority shifts to Signal Strength.
• Signal Strength - Devices with the weakest signal strength will be kicked first.
Note: If you enable this function, you should ensure that there are multiple APs within the
broadcast radius that can accept any rejected or kicked wireless clients; otherwise,
a wireless client attempting to connect to an overloaded AP will be disassociated
permanently and never be allowed to connect.
Click Apply to save your changes back to the NWA/WAC.
Click Reset to return the screen to its last-saved settings.
