We are in the process of doing an OOB VGW (wired) NAC implementation (4.7(2)) and some users are running virtual machines. The base OS's of the devices are Linux (no agent), Windows 7 and MACs.
How does NAC treat the virtual instance? My concern is that the virtual session, from what I have seen creates a unique mac address so that can have two mac addresses from one physical machine on the same vlan and same port.
Will the creation of the second mac trigger a mac notification trap possibly putting the port back into authentication mode?
Just a bit curious because I want to be prepared.
What the heck do folks normally do with Linux devices in NAC?
