With this method, multiple peer switches might find the same access point. The first association
always takes precedence. The AP does not change its association unless the connectivity to the
current wireless switch fails or the switch tells the AP to disassociate and associate with another
switch.
The Discovery tab is available from the WLAN > Basic Setup page and allows you to configure the switch to discover APs
and other switches by using methods 3 and 4.
In order for the Unified Switch to discover other WLAN devices and establish communication with them, the devices must
have their own IP address, must be able to find other WLAN devices, and must be compatible.
When the Unified Switch discovers and validates APs, the switch takes over the management of the AP. If you configure the
AP in Standalone mode, the existing AP configuration is replaced by the default AP Profile configuration on the switch.

L3/IP Discovery

You can configure up to 256 IP addresses in the Unified Switch for potential peer switches and APs. The switch sends
association invitations to all IP addresses in this list. If the device accepts the invitation and is successfully validated by the
switch, the switch and the AP or peer switch are associated.
This discovery method mechanism is useful for peer switch discovery and AP discovery when the devices are in different IP
subnets. In fact, for a switch to recognize a peer that is not on the same subnet, you must configure the IP addresses of each
switch in the peer's L3 discovery list.
The list of IP addresses is separate and independent from the list of valid managed APs. Devices
discovered through this list might not be valid APs or switches.
