Verifying the configuration
1. When AC 1 goes down, AC 3 becomes the new active AC.
2. When AC 1 recovers, the AP connecting to AC 3 connects to AC 1 again. This is because the
highest AP connection priority of 7 on AC 1 ensures an automatic switchover.
AP-based session-mode load balancing configuration example
Network requirements
• As shown in Figure 629 , all APs operate in 802.11g mode. Client 1 is associated with AP 1. Client
2 through Client 6 are associated with AP 2.
• Configure session-mode load balancing on the AC. The threshold, that is, the maximum number of
sessions, is 5, and the session gap is 4.
