Description 

Use the 

bpdu-drop any

 command to enable BPDU dropping on the Ethernet port. 

Use the 

undo bpdu-drop any

 command to disable BPDU dropping on the Ethernet port. 

By default, BPDU dropping is disabled.   

In a STP-enabled network, some users may send BPDU packets to the switch continuously in order to 

destroy the network. When a switch receives the BPDU packets, it will forward them to other switches. 

As a result, STP calculation is performed repeatedly, which may occupy too much CPU of the switches 

or cause errors in the protocol state of the BPDU packets.   

In order to avoid this problem, you can enable BPDU dropping on Ethernet ports. Once the function is 

enabled on a port, the port will not receive or forward any BPDU packets. In this way, the switch is 

protected against the BPDU packet attack and the STP calculation correctness is ensured. 

Examples 

# Enable BPDU dropping on GigabitEthernet 1/0/1.
