Description
Use the bpdu-drop any command to configure the BPDU packets drop function on an
Ethernet port.
Use the undo bpdu-drop any command to disable the BPDU packets drop function on
an Ethernet port.
By default, the BPDU packets drop function is disabled on a port.
In an STP-enabled network, someone may ceaselessly send BPDU packets to a switch
for malicious purpose. The switch forwards BPDU packets to other switches by
receiving them, making the STP calculation occurs constantly. Those result in high
CPU consumption, error protocol state of BPDU packets, and so on.
To avoid those problems, you can enable the BPDU packets drop function on the
Ethernet port of the switch. With this function enabled, the port will neither receive nor
forward the BPDU packets, so as to avoid the BPDU packets attack and ensure correct
STP calculation.
Example
# Enable the BPDU packets drop function on Ethernet1/0/1.
