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.
