▪Aktifkan BPDU filter pada interfacee0/0 SW1
Konfigurasi portfast
SW1
SW1(config)#interface e0/0SW1(config-if)#spanning-tree portfast
SW1(config-if)#spanning-tree bpdufilter enable
SW1#clear spanning-tree counters interface e0/0 hapus dulu nilai bpdu bila sebelumnya sudah ada nilainya

SW1#show spanning-tree interface e0/0 detail
Port 1 (Ethernet0/0) of VLAN0001 is designated forwarding
Port path cost 100, Port priority 128, Port Identifier 128.1.
Designated root has priority 32769, address aabb.cc00.0100
Designated bridge has priority 32769, address aabb.cc00.0100
Designated port id is 128.1, 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 edge mode
Link type is point-to-point by default
Bpdu filter is enabled
BPDU: sent 0, received 0
Terlihat bahwasanya nilai BPDU yang sent dan received akan selalu 0 karena di filter. Berbeda pada BPDU Guard dImana portnya akan langsung menjadi down, maka pada BPDU Filterinterfacenya masih tetap UP.
