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.

Abstract translation: 服务器与具有到端点设备的网络连接的网络设备通信。 服务器从网络设备接收包括端点设备的媒体访问控制（MAC）地址的分组。 确定MAC地址的至少一部分是否与已知端点设备的MAC地址的存储信息匹配。 从分组中提取携带端点设备的进一步描述信息的一个或多个属性。 根据策略规则确定端点设备是否可以按粒度级别进行分类。 如果端点设备不能按照粒度级别进行分类，则基于从分组提取的一个或多个属性和MAC地址来动态地选择探测功能以收集关于端点设备的附加数据。
