•
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.
•
Do not enable BPDU tunneling for DLDP, EOAM, LACP, LLDP, PAGP, or UDLD on the member port
of a Layer 2 aggregation group.
Enabling BPDU tunneling
This section describes how to enable BPDU tunneling.
Enabling BPDU tunneling for a protocol in Layer 2 Ethernet
interface view or port group view
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter Ethernet interface
view or port group view.
•
Enter Layer 2 Ethernet interface view:
interface interface-type
interface-number
•
Enter port group view:
port-group manual port-group-name
Use one of the commands.
3.
Enable BPDU tunneling for
a protocol.
bpdu-tunnel dot1q { cdp | dldp | eoam
| gvrp | hgmp | lacp | lldp | pagp |
pvst | stp | udld | vtp }
By default, BPDU tunneling is
disabled.
Enabling BPDU tunneling for a protocol in Layer 2 aggregate
interface view
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter Layer 2 aggregate
interface view.
interface bridge-aggregation
interface-number
N/A
3.
Enable BPDU tunneling for a
protocol on the Layer 2
aggregate interface.
bpdu-tunnel dot1q { cdp | gvrp |
hgmp | pvst | stp | vtp }
By default, BPDU tunneling is
disabled.
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.
