Abstract
A server is in communication with a network device that has network connectivity to an endpoint device. The server receives from the network device a packet that includes a Media Access Control (MAC) address of the endpoint device. A determination is made as to whether at least a portion of the MAC address matches stored information for MAC addresses of known endpoint devices. One or more attributes that carry further descriptive information of the endpoint device are extracted from the packet. It is determined based whether the endpoint device can be classified at a level of granularity according to a policy rule. If the endpoint device cannot be classified at the level of granularity, a probe function is dynamically selected based on the one or more attributes extracted from the packet and the MAC address to collect additional data about the endpoint device.
