Figure 806 Backing up the IP address of AC 2
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.
Client information backup configuration example
Network requirements
As shown in Figure 528 , AC 1 and AC 2 support stateful failover. AC 1 is the primary AC. Enable client
information backup on the two ACs so the clients can communicate during a primary/backup switchover.
The client in this example is a client that uses clear-type service template for accessing the network.
