I realize this thread is a little old, but I did want to make a comment in regards to this. As a QSA, *wired* side scanning alone would be insufficient to meet the intent of the PCI DSS 11.1 requirement. There is this quote from PCI Council:

"Relying on wired side scanning tools (e.g. tools that scan suspicious hardware MAC addresses on switches) may identify some unauthorized wireless devices; however, they tend to have high false positive/negative detection rates. Wired network scanning tools that scan for wireless devices often miss cleverly hidden and disguised rogue wireless devices or devices that are connected to isolated network segments. Wired scanning also fails to detect many instances of rogue wireless clients. A rogue wireless client is any device that has a wireless interface that is not intended to be present in the environment."
