Commands
1.1 BPDU Tunneling Configuration Commands
1.1.1 bpdu-tunnel dot1q enable
Syntax
bpdu-tunnel dot1q enable
undo bpdu-tunnel dot1q enable
View
System view, Ethernet interface view, port group view
Default Level
2: System level
Parameters
None
Description
Use the bpdu-tunnel dot1q enable command to enable BPDU tunneling.
Use the undo bpdu-tunnel dot1q enable command to disable BPDU tunneling.
Configured in system view, the command enables or disables BPDU tunneling globally;
configured in Ethernet interface view, the setting is effective on the current port only;
configured in interface view, the command enables or disables BPDU tunneling on the
current port only; configured in port group view, the command enables or disables
BPDU tunneling on all ports in the port group.
By default, BPDU tunneling is enabled globally but disabled for all ports.
Note:
zThe configured BPDU tunneling on a port cannot take effect unless BPDU
tunneling is enabled globally.
zOn an Ethernet interface, BPDU tunneling is not compatible with GVRP. To enable
BPDU tunneling on the Ethernet interface, you must disable GVRP on the interface.

1.1.2 bpdu-tunnel dot1q stp
Syntax
bpdu-tunnel dot1q stp
undo bpdu-tunnel dot1q stp
View
Ethernet interface view, port group view
Default Level
2: System level
Parameters
None
Description
Use the bpdu-tunnel dot1q stp command to enable STP BPDU tunneling for a port or
a group of ports.
Use the undo bpdu-tunnel dot1q stp command to disable STP BPDU tunneling for a
port or a group of ports.
By default, STP BPDU tunneling is disabled for all ports.
Configured in Ethernet interface view, the setting is effective on the current port only;
configured in port group view, the setting is effective on all ports in the port group.
Caution:
Before you can enable STP BPDU tunneling on a port, enable BPDU tunneling and
disable STP on the port.
