working. My config is: interface FastEthernet0/18 load-interval 30 switchport access vlan 880 spanning-tree bpdufilter enable no cdp enable enable errdisable recovery end When I do a "sh spanning-tree vlan 880", I get Spanning tree 880 is not currently active The following parameters have been configured : Stp Status : https://supportforums.cisco.com/document/15446/port-status-errdisable-due-bpdu-guard Disabled Protocol : IEEE Max Age (sec) : 20 Hello time (sec) : 2 Forward Delay (sec): 15 Bridge Priority : 32768 You will notice that enabling BPDU filter on the interface is kind of overkill if STP is disabled for VLAN 880 anyway. But nonetheless, the IX guy gets the following when he 'no shuts' its interface http://www.gossamer-threads.com/lists/cisco/nsp/39354 (where BPDU guard is enabled) : .Jan 30 09:50:07: %LINK-3-UPDOWN: Interface GigabitEthernet2/5, changed state to up .Jan 30 09:50:07: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/5, changed state to up Jan 30 09:50:07: %LINK-SP-3-UPDOWN: Interface GigabitEthernet2/5, changed state to up Jan 30 09:50:07: %LINEPROTO-SP-5-UPDOWN: Line protocol on Interface GigabitEthernet2/5, changed state to up .Jan 30 09:50:08: %SYS-5-CONFIG_I: Configured from console by pieter on vty0 (193.190.198.37) .Jan 30 09:50:11: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/5, changed state to down Jan 30 09:50:11: %SPANTREE-SP-2-BLOCK_BPDUGUARD: Received BPDU on port GigabitEthernet2/5 with BPDU Guard enabled.
