N2248PX-ON equivalent for "spanning tree portfast bpduguard default"

Hello, 

On Dell N-Series switches, the Cisco command spanning-tree portfast bpduguard default is roughly equivalent to enabling BPDU protection globally and applying PortFast on edge ports.

spanning-tree portfast bpduguard default behavior on Dell N-Series switches is achieved by combining BPDU Protection with PortFast (edge port).

• BPDU Protection works like BPDU Guard: if an edge port receives a BPDU, it’s disabled to prevent loops.
• PortFast allows access ports to skip STP listening/learning for faster connectivity.

The exact steps depend on your firmware, so check Dell’s official documentation for details:

• Dell Networking N-Series STP Guide (OS10/NOS)
• Dell BPDU Protection Feature Overview

I think, enable BPDU Protection globally and apply PortFast to edge ports for similar functionality.

Hope that helps!
