BPDUguard (does prevent access switches to receive bpdu packets from other foreign switches because the port will go to be error-disable)
So far so good...
I was sniffing a switch port with the following config:
config-if>spanning-tree bpduguard enable
I still receive stp traffic from the switch port on my sniffer???
config-if>spanning-tree bpdufilter enable
Than I can't sniff any stp traffic on the sniffed port.
How does it make sense that an access port just with portfast and bpduguard enabled, does send out any stp traffic if otherwise the port goes down when it receive stp (bpdu) traffic???
For me this scenario does not really make sense?
Any help are appreciated
