Usage Guidelines

Usage Scenario

You can run the display bpdu-tunnel interface config command to view the following information.

Whether BPDUs sent from the interface are tagged
Whether interface-based BPDU tunneling is configured
Whether the interface allows tagged BPDUs to pass
EthType of the outer VLAN tag
VLAN ID of BPDUs sent from the interface
VLAN ID of BPDUs that the interface allows to pass

Precautions

The display bpdu-tunnel interface config command can be run only in the interface view.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display bpdu-tunnel interface config** command output
Item	Description
BpduDot1qStatus	Whether BPDUs sent from the interface are tagged. enable is displayed, if the stp bpdu vlan command is configured on the interface. disable: BPDUs sent from the interface are tagged. enable: BPDUs sent from the interface are untagged.
BpduOneQStatus	Whether interface-based BPDU tunneling is configured on the interface to transparently transmit BPDUs from user networks. enable is displayed, if the bpdu-tunnel enable command is configured on the interface. disable: Interface-based BPDU tunneling is configured on the interface to transparently transmit BPDUs from user networks. enable: Interface-based BPDU tunneling is not configured on the interface to transparently transmit BPDUs from user networks.
BpduTwoQStatus	Whether the interface allows tagged BPDUs to pass. enable is displayed, if the bpdu-tunnel stp vlan command is configured on the interface. disable: The interface allows tagged BPDUs to pass. enable: The interface does not allow tagged BPDUs to pass.
EtherType	EthType of the outer VLAN tag. The default value is 0x8100. Value configured in the qinq protocol ethertype-value command.
Dot1qVlan	VLAN ID of the BPDUs that the interface sends. The value is vlan-id specified in the stp bpdu vlan command.
TwoQList	VLAN ID of BPDUs that the interface allows to pass. The value is vlan-id specified in the bpdu-tunnel stp vlan command.
