There are many ways to obtain the MAC address of an Eni, such as NETBIOS, SNMP, and getadaptersinfo. After testing, it is found that the NetBIOS method cannot obtain the Mac when the network cable is pulled out, while the SNMP method sometimes gets the MAC of multiple duplicate network adapters. It is better to try to use the getadaptersinfo method, mac can be obtained when the
