How AP Discovery Works
There are three types of access point discovery:
 Layer 2 only—Access point is in same subnet as controller.
 Layer 2 preferred—Access point sends broadcasts to find the controller by trying
Layer 2 discovery first. If the access point gets no response, it tries Layer 3
discovery.
 Layer 3 preferred—Access point send broadcasts to find the controller by trying
Layer 3 discovery first. If the access point gets no response, it tries Layer 2
discovery.
For Layer 2 and Layer 3 discovery, the access point cycles between Layer 2 and Layer
3 until it finds the controller. The access point waits 16 seconds before cycling
between Layer 2 and Layer 3.
An access point obtains its own IP address from DHCP (the default method), or you
can assign a static IP address. After the access point has an IP address, it must find
a controller’s IP address. By default, when using Layer 3 discovery, the access point
obtains the controller’s IP address by using DNS and querying for hostname
