Automatic Discovery of Parent and Backup Parent Wireless APs

The children wireless APs, including the Repeater wireless AP and the Satellite wireless APs, scan for their respective parents at a startup.

You can manually configure a parent and backup parent for the children APs or you can enable the children APs to automatically select the best parent out of all of the available APs. If you choose automatic parent AP selection, a child AP selects a parent AP based on its received signal strength and the number of hops to the root AP. After a parent AP and backup parent AP is selected, the wireless controller will first try to negotiate a WDS link with the parent wireless controller. If the WDS link negotiation is unsuccessful, the wireless controller will try to negotiate a link with the backup parent.
