Default Level

Parameters
None
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.
