Switching Lab 8 : STP Features : BPDU Filter

 LAB 8

▪ Konfigurasikan spanning tree portfast pada port akses SW1 

▪Aktifkan BPDU filter pada interfacee0/0 SW1 

Konfigurasi portfast

SW1

SW1(config)#interface e0/0 
SW1(config-if)#spanning-tree portfast 

SW1(config-if)#spanning-tree bpdufilter enable 

hapus dulu nilai bpdu bila sebelumnya sudah ada nilainya

SW1

SW1#clear spanning-tree counters interface e0/0 
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.
