    • Techniques are provided for detecting and identifying host devices in a network. At a switch device, a packet is received from a server that is interfaced with a switch device and is configured to host a virtual machine that is a source of the packet. A Media Access Control (MAC) address or an Internet Protocol (IP) address is identified. The MAC address and IP address are associated with the virtual machine. In response to identifying the MAC or IP addresses, the switch device determines whether a binding between the IP and MAC addresses of the virtual machine is present in a database of addresses accessible by the switch device. If the association is not present, based on the fields obtained from the packet header, a request message is sent to the virtual machine to resolve the association between the IP address and the MAC address of the virtual machine.
    • 提供了用于检测和识别网络中的主机设备的技术。 在交换机设备处,从与交换机设备接口的服务器接收分组,并且被配置为托管作为分组的源的虚拟机。 识别媒体访问控制(MAC)地址或互联网协议(IP)地址。 MAC地址和IP地址与虚拟机相关联。 响应于识别MAC或IP地址,交换机设备确定虚拟机的IP和MAC地址之间的绑定是否存在于由交换设备可访问的地址的数据库中。 如果关联不存在,则基于从分组头获得的字段,向虚拟机发送请求消息以解决虚拟机的IP地址和MAC地址之间的关联。
