Precautions

If standby AC IP addresses are configured in both the WLAN view and AP system profile view before an AP goes online, the standby AC IP address configured in the AP system profile view is delivered to an AP. If no standby AC IP address is configured in the AP system profile view, the standby AC IP address configured in the WLAN view is delivered to an AP. If no standby AC IP address is configured in the WLAN view, dual-link backup is disabled.

The standby AC's IP address must be set to the same as the CAPWAP source address of the standby AC.

Example

# Set the standby AC IP address to 10.33.12.56 in the WLAN view.
