Abstract: A first address resolution request may be received by a first access switch from a first device and the address resolution request may be resolved by the first access switch with a central database of a network. Then a second address resolution request may be sent to a sensor by the first access switch in response to resolving the first address resolution request. An address resolution response may then be sent by the sensor to the first device in response to the sensor determining that the first device is a bad endpoint. A session may then be established between the sensor and the first device in response to the sensor sending the address resolution response. The first device may then be prompted by the sensor via the established session to resolve issues that lead the sensor to determine that the first device is a bad endpoint.
