Julio,
the difference is that with BPDUguard if a bpdu is received on a port woth
portfast enabled, it will shut down that port and put it as err-disable.
if BPDUfilter is enabled globbaly, and a port with portfast enabled receives a
BPDU it will disable portfast and treat that port like a normal STP
port.(discarding->learning->forwarding)
if BPDUfilter is enabled locally ie in interface mode it will ignore BPDUs
received on that port.
Please correct me if i am wrong.
