Chapter 1 BPDU Tunneling Configuration 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
Parameter
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.
BPDU tunneling enables a geographically segmented user network to transmit bridge protocol data units (BPDUs) transparently over the specified virtual local area network (VLAN) of the operator network. This allows the user network to participate in a uniform spanning tree calculation while maintaining a separate spanning tree from the operator network.
By default, BPDU tunneling is disabled.
Caution:
Be sure to enable the STP protocol before enabling BPDU tunneling on a device.
Example
# Enable BPDU tunneling on the switch.

[H3C] bpdu-tunnel dot1q enable
1.1.2 bpdu-tunnel dot1q stp
Syntax
bpdu-tunnel dot1q stp
undo bpdu-tunnel dot1q stp
View
Ethernet port view
Parameter
None
Description
Use the bpdu-tunnel dot1q stp command to enable BPDU tunneling on the port.
Use the undo bpdu-tunnel dot1q stp command to disable BPDU tunneling on the port.
By default, BPDU tunneling is disabled on all ports.
& Note:
l To have BPDU tunneling take effect on a port, you must enable BPDU tunneling not only on the port but also globally.
l BPDU tunneling is mutually exclusive with STP in Ethernet port view.
l VLAN-VPN is mutually exclusive with BPDU tunneling in Ethernet port view.
l The bpdu-tunnel dot1q enable command must be executed globally for the switch connected with the user access ring in the operator ring, and the stp disable and bpdu-tunnel dot1q stp commands must be executed on the connected ports.
l The undo bpdu-tunnel dot1q enable command must be executed globally for the switches that are not connected with the user access ring in the operator ring.
l When multiple users access the ring, they are identified by VLANs, that is, the default VLAN IDs of the bpdu-tunnel-dot1p stp enabled ports in the operator ring are used to identify different user access rings.
l Any link in the operator ring must permit the traffic of the VLANs of all user access rings to pass through, so that packets can be transmitted correctly. Additionally, the default VLAN ID of any link in the operator ring cannot be the same as that of any user access ring.
l A switch cannot belong to two different user access rings at the same time. That is to say, when a switch in a user access ring connects with a switch in the operator ring, the default VLAN IDs of the ports of the switch in the operator ring must be consistent.
l BPDU tunneling is mutually exclusive with smart link or RRPP on a port.
Example
# Enable BPDU tunneling on Ethernet 3/1/3.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] interface Ethernet3/1/3
[H3C-Ethernet3/1/3] bpdu-tunnel dot1q stp
1.1.3 bpdu-tunnel interface
Syntax
bpdu-tunnel interface { interface-type interface-number [ to interface-type interface-number ] } & <1-10> dot1q stp
undo bpdu-tunnel interface { interface-type interface-number [ to interface-type interface-number ] } &<1-10> dot1q stp
View
System view
Parameter
interface-type: Port type.
interface-number: Port number.
For detailed description of Interface-type and interface-number, refer to the interface command in the Ethernet Port Commands. &<1-10> indicates that you can specify up to 10 ports or port ranges.
Description
Use the bpdu-tunnel interface command to enable BPDU tunneling on the specified port(s).
Use the undo bpdu-tunnel interface command to disable BPDU tunneling on the specified port(s).
By default, BPDU tunneling is enabled on a port.
Example
# Enable BPDU tunneling on Ethernet 2/1/1 through Ethernet 2/1/10.
<H3C> system-view
[H3C] bpdu-tunnel interface ethernet2/1/1 to ethernet 2/1/10 dot1q stp
