out load balancing. A radio in a load balancing group starts load balancing when the maximum
threshold and gap are reached on it. The radio does not accept any association requests unless
the load decreases below the maximum threshold or the gap is less than the maximum gap.
However, if a client has been denied more than the specified maximum times, the AP considers
that the client is unable to associate to any other AP and accepts the association request from the
client.
Load balancing configuration task list
NOTE:
•
If the AC has a load balancing mode configured but has no load balancing group created, it
adopts
AP-based load balancing by default. As long as a load balancing group is created, the AC
adopts Group-based load balancing by default.
• Band navigation and load balancing can be used simultaneously.
Complete these tasks to configure load balancing:

Configuring AP-based load balancing Required.
Use either approach.
• AP-based load balancing: After you
complete Configuring a load balancing mode , the
AC adopts AP-based load balancing by default.
• Group-based load balancing:
Complete Configuring a load balancing mode first.
A load balancing group takes effect only when the
load balancing mode is configured.
Configuring group-based load balancing
Configuring parameters that affect load balancing
Optional.
This configuration takes effect for both AP-based load
balancing and radio group load balancing.
Displaying and maintaining load balancing Optional.
Configuring a load balancing mode
Prerequisites
Before you configure load balancing, make sure of the following:
• The target APs are associated to the same AC.
• The clients can find the APs.
• The fast association function is disabled. By default, the fast association function is disabled. For
more information about fast association, see "Configuring WLAN services."
