We have Cisco switches with port security and 802.1x authentication.
Since starting to deploy L560 laptops (all using docking stations), on ports that have port security setup (limit to 1 MAC address on the port), our ports are being disbaled by port security due to more than 1 MAC address being seen on those ports. Example MAC addresses are below.
Trying to do a MAC address lookup on these addresses, the OUI is coming back as not registered.
Where are these MAC addresses coming from?

There is a firmware update for the NIC on the drivers page. I think it's the GBe NVM updater.
We've had it since January due to having widespread issues. If you have update retriever and System Update/ThinInstaller, the update can be rolled out easily.
That should sort out the problem
