Usage Guidelines

Usage Scenario

To connect an AP to two ACs (active and standby ACs) to implement dual-link backup, you can run the protect-ac command to configure the standby AC's IP address in the AP system profile view.

Precautions

If standby AC's IP addresses are configured in both the WLAN view and AP system profile view, the standby AC's IP address configured in the AP system profile view is delivered to an AP. If no standby AC's IP address is configured in the AP system profile view, the standby AC's IP address configured in the WLAN view is delivered to an AP.

The IP address of the standby AC cannot be specified as the IP address of the local device. Otherwise, the backup function does not take effect.

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's IP address to 10.3.3.3 in the AP system profile view.

[HUAWEI] wlan 
[HUAWEI-wlan-view] ap-system-profile name ap-system1
