N-Series BPDU-Protection?
Can anyone help me understand the new "BPDU-Protection" feature on the N-series switches? It appears to be a replacement for BPDUguard, which is no longer there.
I'm looking for BPDUguard as a way to prohibit rogue devices on edge ports. I've fired up BPDU-protection in my lab on an N3024 that's connected in a ring with a pair of Ciscos. it doesn't appear to be doing anything. I want it to shut down any port on which it receives a BPDU (per BPDUguard). But I'm not clear how this is going to work since BPDU-Protection is a global setting and I would need to exempt my uplinks.
Am I missing something?

yes, the "spanning-tree bpdu-protection" is global setting. and it just effect port configured 'spanning-tree portfast'. both done, when port recevied bpdu it will be shutdown and display "D-Down".
hope it is useful for you.

Thanks Mark. That's helpful. I just tested it out and it worked.
Odd that Dell changed the syntax on that. But I guess if it works then whatever.
