What are the commands required to ensure loop backs cannot occur on our network. We have x2 core 5406zl switches and various edge hps. We aren't too bothered about the edge but the core must have this protection. I'm led to believe it's possible to issue the command at cli but unsure what e best setup is and if it's ok to enable for all ports?
