Hi,This is also being referred to on another thread...https://supportforums.cisco.com/thread/2110512NEX-OS 6.0 is out but I've not seen any confirmation that the non-negotiate command is in there like the 5000's and 2000's...  I've also got a client ...

First turn BPDU Guard and Loop Guard back on in the global config.  You do not want to have that vulnerability on your network, especially if bad STP information may be produced on your network via driver/nic, etc.To answer your original question ---...
