Enable Load
Balancing
Select this to enable load balancing on the NXC.
Use this section to configure wireless network traffic load balancing between the managed
APs in this group. Load balancing only works between APs in the same group. An
overloaded AP will not kick out clients or delay connections if it does not detect another
underloaded AP assigned to the same group (see Table 56 on page 126).
Note: Load balancing is not supported on the radio which is working in root AP or
repeater AP mode.
Mode 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 an AP.
Select By Traffic Level to balance network traffic based on the volume generated by the
stations connected to an AP.
Select By Smart Classroom to balance network traffic based on the number of specified
stations connected to an AP. The AP 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 AP 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.
Radio1/2 Max
Station Number
Enter the threshold number of stations connected to the radio slot at which an AP begins
load balancing its connections.
Radio1/2 Traffic
Level
Select the threshold traffic level of the radio slot at which the AP begins load balancing its
connections (Low, Medium, High).
The maximum bandwidth allowed for each level is:
• Low - 11 Mbps,
• Medium - 23 Mbps
• High - 35 Mbps
Disassociate
station when
overloaded
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 NXC and is as follows:
• Idle Timeout - Devices that have been idle the longest will be disassociated 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 disassociated 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 kicked continuously and never be allowed to
connect.
Rogue AP Detection Setting
