Enabling N+1 Backup

After all N+1 backup configurations are complete, enable N+1 backup and then restart all APs to make the function take effect.

N+1 backup needs to be enabled on all ACs.

Run system-view
The system view is displayed.
Run wlan
The WLAN view is displayed.
Run undo ac protect enable
N+1 backup is enabled.

By default, N+1 backup is enabled.
(Optional) Run ap-reset { all | ap-name ap-name | ap-mac ap-mac | ap-id ap-id | ap-group ap-group | ap-type { type type-name | type-id type-id } }
All APs are restarted to make the N+1 backup function take effect.

If N+1 backup is enabled, running the undo ac protect enable command does not restart online APs. You need to run the ap-reset { all | ap-name ap-name | ap-mac ap-mac | ap-id ap-id | ap-group ap-group | ap-type { type type-name | type-id type-id } } command to restart the APs and make the N+1 backup function take effect. You can also manually restart the APs to make the N+1 backup function take effect.

If the N+1 backup function is disabled, running the undo ac protect enable command restarts online APs. After the APs are restarted, the N+1 backup function starts to take effect.

If an AP goes online after N+1 backup is enabled, you do not need to restart the AP.
