I am running Hyper-V on Server 2012R2. My server has three network connections. One for the Host OS, and two that Hyper-V manages with its virtual switch. All three connections are connected to an 802.1x protected network. The Host Server OS is configured correctly and is getting IP OK, but none of the client OSes can get an IP address and are unable to authenticate despite being correctly configured in the OS. It seems like the Hyper-V virtual switch is maybe not passing the authentication requests back to the client OS, or the client OSes replies are not being sent to the network through the Hyper_V virtual switch??? At any rate, the virtual clients cannot get IP addresses and we can see the authentication failures along with the virtual MAC addresses in the 802.1x management console.
Does Hyper-V running on Server 2012R2 not support 802.1x?
If Hyper-V doesn't, can someone recommend a competing product that does? I'm not married to Hyper-V if it is not capable of working in a standard enterprise environment.
