Enabling BPDU tunneling
You can enable BPDU tunneling for different protocols in different views.
NOTE:
•
Settings made in Layer 2 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 first.
•
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.
•
Do not enable BPDU tunneling for DLDP, EOAM, LACP, LLDP, PAGP, or UDLD on the member port of a
Layer 2 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.
