Abstract
A device blocking tool includes a user interface, a location engine, a retrieval engine, and an update engine. The user interface receives at least one of a MAC address and an IP address of a device. The location engine communicates a query to an access control server, receives a response, and determines, based on the response, that the device connected to a network through a wired connection. In response that determination, the location engine determines a switch through which the device connected. The location engine also determines a number identifying a VLAN through which the device connected and determines that the device is an IP telephone. The retrieval engine retrieves an access control list. The update engine disconnects the device from the VLAN and reconnects the device through a second VLAN.
