Enabling BPDU tunneling
You can enable BPDU tunneling for different protocols in different views.
NOTE:
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 you enable BPDU tunneling for DLDP, EOAM, GVRP, HGMP, LLDP, or STP on a port, disable the protocol
on the port.
Because PVST is a special STP protocol, you must do two things before you enable BPDU tunneling for PVST on a
port: first, disable STP; second, enable BPDU tunneling for STP on the port.
Before you enable BPDU tunneling for LACP on a member port of a link aggregation group, remove the port
from the link aggregation group.

Configuring destination multicast MAC address for BPDUs
By default, the destination multicast MAC address for BPDUs is 0x010F-E200-0003. You can change it to
0x0100-0CCD-CDD0, 0x0100-0CCD-CDD1, or 0x0100-0CCD-CDD2.
