Hi Rene ,
Global: if you enable BPDUfilter globally then any interface with portfast enabled will not send or receive any BPDUs. When you receive a BPDU on a portfast enabled interface then it will lose its portfast status, disables BPDU filtering and acts as a normal interface.
What does it mean of "disables BPDU filtering and acts as a normal interface " ?
“Interface: if you enable BPDUfilter on the interface it will ignore incoming BPDUs and it will not send any BPDUs. This is the equivalent of disabling spanning-tree.”
What if there is portfast enabled on these interface and enable bpdufilter also ?
If this disable spanning tree , There is no use of portfast ?
Thanks
