Usage guidelines
Settings made in Layer 2 Ethernet interface view or Layer 2 aggregate interface view take effect only on
the Ethernet interface or aggregate interface.
Settings made in port group view take effect on all member ports in the port group.
You cannot enable BPDU tunneling on a member port of a service loopback group.
Before you enable BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the
protocol on the port first.
To enable BPDU tunneling for PVST (which is a spanning tree protocol) on a port, disable STP first and
then enable BPDU tunneling for STP on the port.
Do not enable BPDU tunneling for DLDP, EOAM, LACP, LLDP, PAGP, or UDLD on the member port of a
Layer 2 aggregation group.
Examples
# Disable STP on GigabitEthernet 3/0/1, and then enable BPDU tunneling for STP on the port.

# Disable STP for port group 1, and then enable BPDU tunneling for STP in the port group.

bpdu-tunnel tunnel-dmac
Use bpdu-tunnel tunnel-dmac to configure the destination multicast MAC address for BPDUs.
Use undo bpdu-tunnel tunnel-dmac to restore the default value.
Syntax
bpdu-tunnel tunnel-dmac mac-address
undo bpdu-tunnel tunnel-dmac
Default
The destination multicast MAC address for BPDUs is 0x010F-E200-0003.
