Thanks Jason. That type of scenario is pretty easy to identify as needing the passive client feature. I'm more thinking of when WGBs come into the picture. For instance, here is a snippet of of the 7.0.116.0 release notes regarding passive client.
Non-Cisco WGB Support Starting in release 7.0.116.0, the controller software has been updated to accommodate non-Cisco workgroup bridges so that the controller can forward ARP, DHCP, and data traffic to and from the wired clients behind workgroup bridges. This processes is accomplished by enabling the passive client feature. To configure your controller to work with non-Cisco workgroup bridges, you must enable the passive clients feature. All traffic from the wired clients is routed through the work group bridge to the access point. So it seems that when WGBs get into the picture, both passive client and the MAC-to-IP binding features can come into play. When WGBs are mentioned, what's the best way to decide which feature is being asked about (or if both would be needed).
