Chapter 4 BPDU Tunnel Configuration Commands
4-2
Use the
undo bpdu-tunnel
command to disable BPDU tunnel on a port.
By default, BPDU tunnel is disabled on a port.
After you enable a port to transmit packets of a specified protocol type through the
BPDU tunnel, when the port receives such a packet, it will use the specified private
multicast MAC address to replace the original destination MAC address of the packet
before sending it. As a result, the packet will not be recognized as a protocol packet by
other devices in the operator network during transmission. In this way, transparent
transmission is implemented.
You can use the
bpdu-tunnel tunnel-dmac
command to change the destination MAC
addresses of protocol packets to a specified multicast MAC address.
Caution:
z
If this command is enabled on a port for a specific protocol, the specific protocol
cannot be enabled on the port. For example, if you have configured the
bpdu-tunnel lacp
command, the
lacp enable
command cannot be enabled on the
port.
z
The commands configured for service provider’s devices at both ends of a BPDU
tunnel must be consistent. Otherwise, BPDU packets of the customer network
cannot be transparently transmitted properly.
Examples
# Enable BPDU tunnel for packets of LACP.
