One embodiment is directed to detecting that a cable has been connected to a port of patching equipment and detecting that the cable is no longer connected to said port. In response to detecting that the cable is no longer connected, information associated with fixed cabling coupled to said port that is captured by a cable tester is downloaded to a controller. The downloaded information is associated with said port and the downloaded information and association information is locally stored at the controller. The locally stored information can then be used to create and/or populate objects in a database. Another embodiment is directed to including a storage device and a wireless interface in patching equipment or other equipment such as an outlet or consolidation point for use in writing information to the storage device and reading information from the storage device via the wireless interface. Other embodiments are disclosed.
