I want to disable BPDU filter and applied command "spanning-tree bpdufilter disable" under the interface but still I am getting following output that
Bpdu filter is enabled internally.
sh spanning-tree interface
Port 3 (FastEthernet0/1) of VLAN0001 is forwarding Port path cost 19, Port priority 128, Port Identifier 128.3. Designated root has priority 32769, address 0019.2f4d.4580 Designated bridge has priority 32769, address 0019.2f4d.4580 Designated port id is 128.3, designated path cost 0 Timers: message age 0, forward delay 0, hold 0 Number of transitions to forwarding state: 1 Link type is point-to-point by default Bpdu filter is enabled internally BPDU: sent 44, received 1
Please advise how it can be disabled.
after doing this command:
no spanning-tree bpdufilter enable
can you issue:
clear spanning-tree counters
and than watch to see if the counter increases.
currently is is at:
BPDU: sent 44, received 1
After cleared the interface counter I noticed BPDU sent counter was increasing so it looks like default behaviour of running IOS version.
