BPDU Tunneling Configuration Commands 
BPDU Tunneling Configuration Commands 
bpdu-tunnel dot1q stp 
Syntax 
bpdu-tunnel dot1q stp 
undo bpdu-tunnel dot1q stp 
View 
Ethernet interface view, Layer-2 aggregate interface view, port group view 
Default Level 
2: System level 
Parameters 
None 
Description 
Use the bpdu-tunnel dot1q stp command to enable BPDU tunneling for STP on the current port or 
ports.  
Use the undo bpdu-tunnel dot1q stp command to disable BPDU tunneling for STP on the port or 
ports.  
By default, BPDU tunneling for STP is disabled.  
Note that: 
Configuration made in Ethernet interface view takes effect on the current port only. Configuration 
made in Layer-2 aggregate interface view takes effect only on the Layer-2 aggregate interface. 
Configuration made in port group view takes effect on all ports in the port group.  
Configuration made on an aggregation group member port takes effect after the port exits the 
aggregation group. For detailed information about link aggregation, refer to Link Aggregation 
Configuration in the Access Volume.  
Before you can enable BPDU tunneling for STP on a port, disable STP on the port first.  
Examples 
# Enable BPDU tunneling for STP on GigabitEthernet 2/0/1.  
<Sysname> system-view 
[Sysname] interface GigabitEthernet 2/0/1 
[Sysname-GigabitEthernet2/0/1] stp disable 
[Sysname-GigabitEthernet2/0/1] bpdu-tunnel dot1q stp 
# Enable BPDU tunneling for STP on all the ports in port group 1.
