NO BPDU-FIlter disabled by default, the below show spanning-tree interface
x/x detail from one of 3560 catalysts with default configurations, i beleive
there is something wrong in your configurations, because the received BPDU
is so high which is not normal unless the port is trunk, so please check
your config because by default the BPDU-Filter/Guard is disbaled.
Port 6 (FastEthernet0/4) of VLAN0020 is forwarding
Port path cost 19, Port priority 128, Port Identifier 128.6.
Designated root has priority 32788, address 001b.904f.cc00
Designated bridge has priority 32788, address 001b.904f.cc00
Designated port id is 128.6, designated path cost 0
Timers: message age 0, forward delay 0, hold 0
Number of transitions to forwarding state: 1
The port is in the portfast mode
Link type is point-to-point by default
BPDU: sent 5978045, received 0
