@davidhiggs-
That's good info, thanks for the testing. But by this:
The machine doesn't need a firmware or software update to be able to netboot with the adapter.
Your netboot image needs to have the Thunderbolt update applied...
are you talking about the Thunderbolt Software Update vers 1.2 that Apple yanked due to boot issues some people were experiencing? I don't think they've reposted that update to my knowledge. Just curious, because they had a previous 1.1 update released in March with the same name
Whoa! That's really weird. I'm not seeing it on any of my SUS's, not even the NetSUS appliance I have up and running. I wonder why that would be??
Only thing I see from 6/18 is the MacBook Pro (Retina) Trackpad Update.
Thanks for the info ben.
@tlarkin - Auto-detect on my switch is fine for the Thunderbolt adapter, Full-duplex and 1k speeds. A similar experience with the Thunderbolt Display. Both using the PCI bus, seems to be pretty rock solid.
Can't say the same for my USB Ethernet adapter, it only ever connected at Half-duplex 100 speeds on my switch in auto mode. From the reports I see, it should be capable of full-duplex.
@mm2270 - My SUS isn't showing it either. Might be included in 10.7.5 when it comes out, and a manual install for now.
FYI
v1.2 wasn't a problem for my MacBook Pro 8,2. I had a chance to play with it and found the behaviour when plugging in the adapter is different.
Under 1.2, it would drop my Thunderbolt Display NIC, then reconnect it along with the Thunderbolt Ethernet Adapter. Under 1.21, I can insert and remove the Thunderbolt Ethernet adapter without it affecting my Display Thunderbolt NIC.
Our switches were heavily managed, and that is what I suspect was part of the problem. I just remember several of our switches not auto detecting speed properly and it defaults to 10baseT. Due to the time crunch I was in, I never actually figure out why. I just fixed it by doing what I did and moved on. I did find a few online discussion of people having similar issues. The switches were older Cisco ones, could totally be a legacy firmware IOS thing that doesn't recognize USB adapters since some of our switches were old.
This is why I've always carried a Fluke Linkrunner (up to 100) or Fluke Linkrunner Pro (up to 1000). Take a second to see how the port is set up. All too often the switch port was found to be locked to half, or locked to 10 or 100 when 1000 was possible, this, with the network folks saying "the ports are fine, nothing wrong with them".
Time to upgrade, amazingly at a few hundred less than the above...

Yeah I am not sure what the issue was. However, if I had to make a guess I would put my money on the fact it didn't know how to properly detect a USB adapter, and when detection fails it defaults to the slowest speed possible. I know on newer switches this is not really a problem, or at least so I have read on the Internet that is the case.
Good idea to carry around a tool to test the port that is independent of any computer or OS. That will eliminate a lot of possibilities really fast.
Thanks,
Tom
Holy thread resurrection BatMan!! https://jamfnation.jamfsoftware.com/discussion.html?id=2910
But yes, i've seen it too with USB Ethernet Adaptors with some belikin & netgear routers.
