The method further comprises, as a part of the localized read transaction, reading any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first connector comprises an attached RFID tag that is configured to respond to the first type of RFID interrogation signal; and, as a part of the localized read transaction, reading any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second connector comprises an attached RFID tag that is configured to respond to the second type of RFID interrogation signal. Other embodiments are disclosed.

One embodiment is directed to a “software only” hosted or cloud-based physical layer management (PLM) system. Another embodiment is directed to a hosted or cloud-based PLM system or Automated Infrastructure Management (AIM) system that uses a hardware appliance that is locally deployed in an enterprises network. Other embodiments are disclosed.

Systems and methods for network port monitoring using low energy wireless communications are provided. In one embodiment, a device comprises: at least one port module, the at least one port module comprising one or more connector ports each configured to receive a connector of a network data cable; and a port state sensor that includes a port sensing circuit coupled to a sensor controller, wherein the port sensing circuit is configured to sense a port state for the one or more connector ports; wherein the sensor controller is configured to input the port state from the port sensing circuit, wherein in response to detecting a change in the port state from the port sensing circuit, the sensor controller wirelessly transmits port state information to a port state monitor.

Port occupancy can be detected by positioning signal responders on shutters disposed at the ports. The signal responders are detectable when the shutters are undeflected (i.e., the respective ports are available). The signal responders are not detectable when the shutters are deflected (i.e., the respective ports are occupied). The signal responders may include RFID tags. Each shutter having a corresponding signal responder may span more than one port.
