bpdu-drop enable
Drops STP, RSTP, MSTP, and PVST and RPVST bridge protocol data units (BPDUs), disabling the
tunneling of those protocols on an interface.
Synopsis bpdu-drop enable [rx | tx | all]
no bpdu-drop enable [rx | tx | all]
Operands tx Disables tunneling in the transmit direction.
rx Disables tunneling in the receive direction.
all Disables tunneling in both the transmit and receive directions.
Defaults BPDU-drop is disabled.
Command Modes Interface subtype configuration mode
Description Use this command to prevent reception of any STP or PVST BPDUs on a interface. If such a BPDU is
received on a interface that is BPDU-drop enabled, the interface drops the BPDU frames, but does
not shut down.
Usage Guidelines Enter bpdu-drop enable with the tx, rx, or all options. Without an optional keyword, the action
applies to the ingress direction only.
Enter no bpdu-drop enable with the tx, rx, or all options to disable BPDU drop in one or more
directions.
Enter no bpdu-drop enable to disable BPDU-drop completely.
Examples To enable BPDU-drop on a specific 10-gigabit Ethernet interface:
switch(config)# interface tengigabitethernet178/0/9
switch(conf-if-te-178/0/9)# bpdu-drop enable
To disable BPDU-drop on a specific port-channel interface:
switch(config)# interface port-channel 62
switch(conf-port-channel-62)# no bpdu-drop enable
To disable BPDU-drop on a specific port-channel interface in the transmit direction:
switch(config)# interface port-channel 62
switch(conf-port-channel-62)# no bpdu-drop enable tx
