Settings made in Ethernet interface view or Layer 2 aggregate interface view take effect only on the
current port; settings made in port group view take effect on all ports in the port group.
Before enabling BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the
protocol on the port.
To enable BPDU tunneling for PVST (which is an spanning tree protocol) on a port, disable STP first and
then enable BPDU tunneling for STP on the port.
Before enabling BPDU tunneling for LACP on a member port of a link aggregation group, remove the
port from the link aggregation group.

bpdu-tunnel tunnel-dmac
Syntax
bpdu-tunnel tunnel-dmac mac-address
undo bpdu-tunnel tunnel-dmac
View
System view
Default level
2: System level
Parameters
mac-address: Destination multicast MAC address for BPDUs, in the format of H-H-H. The allowed values
are 0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1, 0x0100-0CCD-CDD2, and 0x010F-E200-0003.
Description
Use the bpdu-tunnel tunnel-dmac command to configure the destination multicast MAC address for
BPDUs.
Use the undo bpdu-tunnel tunnel-dmac command to restore the default value.
