I don't see why it won't support mixed access points. yes, the bundles include certain APs but the controller is still a 2504. therefore, it will support any other AP that it is compatible with, regardless of what bundle was initially purchased.
The Catalyst 4500E is expected to be hardware-capable of supporting AVB by late calendar year 2013.Other switches, e.g. Catalyst 3k, other 4k series and 6500, only mentioned AVVID support, nothing about AVB. Cisco AVVID http://www.cisco.com/global/A...
