Load-balancing modes

The AC supports two load balancing modes, session mode and traffic mode.

Session mode load-balancing:
Session-mode load balancing is based on the number of clients associated with the AP/radio.
As shown in

Figure 61

, Client 1 is associated with AP 1, and Client 2 through Client 6 are

associated with AP 2. The AC has session-mode load balancing configured: the maximum number

of sessions is 5 and the maximum session gap is 4. Then, Client 7 sends an association request to
AP 2. The maximum session threshold and session gap have been reached on AP 2, so it rejects

the request. At last, Client 7 associates with AP 1.
