An access point must run at least its initial firmware release or a newer version. No other firmware requirements exist for the access point to function with the wireless controller.
Access points in factory default state that are in the same Layer 2 network can have the same IP address and still be discovered. Depending on the configuration of the DHCP server, these access points are discovered in parallel or sequentially.
DHCP option 43 (vendor-specific information) must be enabled on an external DHCP server. Specifying an internal DHCP server on the wireless controller automatically enables DHCP option 43 with the IP address of the wireless controller.
