Usage Guidelines

Usage Scenario

To ensure service stability, an AP needs to establish connections with two ACs. The two ACs work in active/standby mode. The active AC provides services for APs, whereas the standby AC is a backup to the active AC.

Follow-up Procedure

After dual-link backup or N+1 backup is enabled globally, configure the AC priority and standby AC IP address to implement dual-link backup or N+1 backup.


Ensure that active and standby ACs deliver the same WLAN service configuration to an AP that connects to the two ACs.


# Enable dual-link backup globally and disable N+1 backup.
