BPDU tunneling configuration commands 
bpdu-tunnel dot1q 
Syntax 
In Ethernet interface view or port group view: 
bpdu-tunnel dot1q { cdp | dldp | eoam | gvrp | hgmp | lacp | lldp | pagp | pvst | stp | udld | vtp } 
undo bpdu-tunnel dot1q { cdp | dldp | eoam | gvrp | hgmp | lacp | lldp | pagp | pvst | stp | udld 
| vtp } 
In Layer 2 aggregate interface view: 
bpdu-tunnel dot1q { cdp | gvrp | hgmp | pvst | stp | vtp } 
undo bpdu-tunnel dot1q { cdp | gvrp | hgmp | pvst | stp | vtp } 
View 
Ethernet interface view, port group view, Layer 2 aggregate interface view 
Default level

eoam: Enables BPDU tunneling for Ethernet Operation, Administration and Maintenance (EOAM). 
gvrp: Enables BPDU tunneling for the GARP VLAN Registration Protocol (GVRP). 
hgmp: Enables BPDU tunneling for the HW Group Management Protocol (HGMP). 
lacp: Enables BPDU tunneling for the Link Aggregation Control Protocol (LACP). 
lldp: Enables BPDU tunneling for the Link Layer Discovery Protocol (LLDP). 
pagp: Enables BPDU tunneling for the Port Aggregation Protocol (PAGP). 
pvst: Enables BPDU tunneling for Per VLAN Spanning Tree (PVST). 
stp: Enables BPDU tunneling for the Spanning Tree Protocol (STP).

vtp: Enables BPDU tunneling for the VLAN Trunking Protocol (VTP). 
Description 
Use the bpdu-tunnel dot1q command to enable BPDU tunneling for a protocol on the port or ports.  
Use the undo bpdu-tunnel dot1q command to disable BPDU tunneling for a protocol on the port or ports.  
By default, BPDU tunneling for any protocol is disabled.
