1.1.2 bpdu-drop any
Syntax
bpdu-drop any
undo bpdu-drop any
View
Ethernet port view
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.

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