Cisco Catalyst 3560 switch. SW version 12.2(25) SEE3.
Interface Gi 0/25 (optical SFP connector) is connected to external equipment. Switchport mode trunk.
I don't need Spannnig tree on VLAN's which are allowed on this trunk port.
So I have disabled Spanning tree for these VLAN's.
no spannig-tree vlan xxx
Additionally I have set this port to PortFast Mode
spanning-tree portfast trunk
And enabled BPDU Filtering
spanning-tree bpdufilter enable
But I still see with Wireshark Analyzer outgoing BPDU from this Interface. Source MAC is Gi 0/25 port MAC address.
I have attached spanning tree configuration and Wireshark capture file.
Could You explain why BPDU messages are not filtered ?
With Best Regards
