Hello,
I am wondering why you would want to implement the BPDUGUARD on a live network taking into consideration that the port will be put in errdisable state.
Is it not better to just use bpdufilter on the interface and disregards any bpdu?
Please let me know if bpduguard add any more functionality than want you obtain from bpdufilter when enable on a port.
Regards//
