Issue Description

We would like to know if, by default, all the following layer 2 protocols are transparently forwarded by MA5600 from DSL port to uplink port ?

o IEEE 802.1d (Spanning Tree)
o IEEE 802.1w (Rapid Spanning Tree)
o IEEE 802.1s (Multiple Instance of Spanning Tree)
o LACP (Link Aggregation Control Protocol)
o OAM EFM (Ethernet First Mile IEEE 802.3ah)
o IEEE 802.3x (Flow Control - PAUSE )
o IEEE 802.1x (Port Authentication protocol )
o Bridge Management Group Block of Protocols
o GARP (Generic Attribute Registration Protocol)
o LLDP (Link Layer Discovery Protocol )

If not transparent by default, can we configure transparency by vlan ?

We have MA5600 V800R003C03.

Solution

We have searched in the documentation and have deduced the following:

o IEEE 802.1d (Spanning Tree)    //Only transparent QinQ vlan packets when enable global bpdu tunnel
o IEEE 802.1w (Rapid Spanning Tree)    // Only transparent QinQ vlan packets when enable global bpdu tunnel
o IEEE 802.1s (Multiple Instance of Spanning Tree)   // Only transparent QinQ vlan packets when enable global bpdu tunnel
o LACP (Link Aggregation Control Protocol)    // Only transparent QinQ vlan packets when enable global bpdu tunnel
o OAM EFM (Ethernet First Mile IEEE 802.3ah) // Only transparent QinQ vlan packets when enable global bpdu tunnel
o IEEE 802.3x (Flow Control - PAUSE )                //Not transparent
o IEEE 802.1x (Port Authentication protocol )    // Transparent
o Bridge Management Group Block of Protocols   
// Need to check what’s the specific protocol packets, if it is bpdu, Only transparent QinQ vlan packets when enable global bpdu tunnel
If the device does not identify the packet, it transparently transmits the packet. If the packet is a multicast packet, it is affected by the unknown multicast switch and unknown multicast suppression.
o GARP (Generic Attribute Registration Protocol)    // Only transparent QinQ vlan packets when enable global bpdu tunnel
o LLDP (Link Layer Discovery Protocol )    // Only transparent QinQ vlan packets when enable global bpdu tunnel

“If not transparent by default, can we configure transparency by vlan ?”

The bpdu tunnel for MA5600 only support configure at global mode
To enable the transparent transmission of BPDUs, do as follows:
huawei(config)#bpdu tunnel enable

To disable the transparent transmission of BPDUs, do as follows:
huawei(config)#bpdu tunnel disable
