The L2PT BPDU and BPDU tunnel functions are mutually exclusive:

1. The values of <group-mac> in the l2protocol-tunnel group-mac <group-mac> and bpdu-tunnel stp group-mac <group-mac> commands in the system view cannot be the same.

2. The l2protocol-tunnel stp enable and bpdu-tunnel enable commands are mutually exclusive in the interface view.

When STP/RSTP/MSTP is not enabled on a Layer 2 interface, the default action to be taken on BPDUs/BPDU08s is discard. When STP/RSTP/MSTP is enabled on a Layer 2 interface, the default action to be taken on BPDUs/BPDU08s is send.

1. When STP is disabled on a Layer 2 main interface, the VLAN service cannot forward BPDU/BPDU08s.

2. After STP is disabled on a Layer 2 main interface, sub-interfaces of the interface cannot forward BPDU/BPDU08s if VLL/VPLS/BD/EVPN services are configured on the sub-interfaces.

3. When STP is disabled on a Layer 2 main interface, the L2PT function for BPDUs is unavailable on both the main interface and its sub-interfaces.

It is advised to run the stp bpdu bridge enable command in the system view.

After the STP, LACP, LLDP, and ETOAM services are enabled, the transparent transmission function of the corresponding protocol does not take effect.

NetEngine 8000 F2A/NetEngine 8000 F1A

When STP/RSTP/MSTP is disabled on a main interface, the default action to be taken on protocol packets with the destination MAC address 0180-C200-0008 is discard.

It is advised to run the stp bpdu bridge enable command in the system view.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

When STP/RSTP/MSTP is not enabled on a main interface and a common sub-interface accesses VPLS/VLL, the default action for protocol packets with the destination MAC address of 0180-C200-0000 is discard.

It is advised to run the stp bpdu bridge enable command in the system view.

NetEngine 8000 F

NetEngine 8000 F2A/NetEngine 8000 F1A

When STP/RSTP/MSTP is not enabled on a main interface and the main interface accesses VPLS/VLL, the default action for protocol packets with the destination MAC address of 0180-C200-0000 is discard.

It is advised to run the stp bpdu bridge enable command in the system view.
