Can the interfaces without BPDU enabled send BPDUs

15

The BPDU function affects only BPDU receiving. Therefore, the interfaces not enabled with the BPDU function can still send BPDUs.

If the BPDU function is not enabled, functions such as LACP, LLDP, STP, and HGMP that communicate through BPDUs are affected.

NOTE:
The S2700 enables the BPDU function globally rather than on interfaces.

The S3700, S5700, and S6700 need to enable the BPDU function on only interfaces.

Can interfaces on S series switches where the BPDU function is not enabled send BPDUs
To configure S series (except the S1700) and E series switches to transparently transmit BPDUs, perform the following operations: 1. Configure interface-based Layer 2 protocol transparent transmission. (1) Run the l2protocol-tunnel group-mac command in the system view to replace the multicast destination MAC address of Layer 2 protocol packets with a specified multicast MAC address. (2) Run the port default vlan command on the inbound and outbound interfaces to transparently transmit untagged BPDUs. (3) Run the l2protocol-tunnel { all | protocol-type } enable command on the inbound and outbound interfaces to enable interface-based Layer 2 protocol transparent transmission. 2. Configure VLAN-based Layer 2 protocol transparent transmission. (1) Run the l2protocol-tunnel group-mac command in the system view to replace the multicast destination MAC address of Layer 2 protocol packets with a specified multicast MAC address. (2) Run the port link-type hybrid and port hybrid tagged vlan commands on the inbound and outbound interfaces to transparently transmit tagged BPDUs. (3) Run the l2protocol-tunnel { all | protocol-type } vlan command on the inbound and outbound interfaces to enable VLAN-based Layer 2 protocol transparent transmission.

What is the function of the bpdu enable command
The bpdu enable command is used to enable the port or global BPDU processing capacity. The BPDUs are not discarded on the port.

How can I configure BPDU tunnel to transparently transmit BPDUs
To transparently transmit untagged BPDUs, run the port default vlan command on the inbound and outbound interfaces of the BPDUs. To transparently transmit tagged BPDUs, run the port default vlan command on the outbound interface of the BPDUs.

Can BPDUs be transparently transmitted on a device
After the bpdu enable command is used on an interface, the interface sends received BPDUs to the CPU for processing. The local device determines whether to process BPDUs of a protocol depending on whether the protocol is enabled. For example, whether STP BPDUSs on an interface are sent to the CPU depends on whether STP has been enabled on the interface using the stp enable command. After the bpdu disable command is used on an interface, BPDUs received on this interface are discarded by the chip. To transparently transmit BPDUs on a device, enable Layer 2 protocol transparent transmission on the device interfaces. In V100R005 and later versions, run the l2protocol-tunnel all enable command on an interface to enable Layer 2 protocol transparent transmission. To ensure successful forwarding of packets, configure the default VLAN on the inbound and outbound interfaces of all devices on the forwarding path.
