Parameters
None
Description
Use the vlan-vpn inner-cos-trust enable command to enable the inner-to-outer tag
priority replicating feature.
With the feature enabled, a port replicates the inner tag priority to the outer tag when
adding an outer tag for a packet.
Use the undo vlan-vpn inner-cos-trust command to disable the feature.
By default, the inner-to-outer tag priority replicating feature is disabled, and the switch
will use the priority of the receiving port as the outer tag priority of packets. For
descriptions on receiving port priority, refer to QoS-QoS Profile Operation.
Note that:
z This feature can be enabled only on VLAN-VPN-enabled ports.
z This command is mutually exclusive with the vlan-vpn priority command.

View
Ethernet port view
Parameters
value: User-defined TPID value (in hexadecimal format), in the range 0x0001 to
0xFFFF.
Description
Use the vlan-vpn tpid command to set the TPID value for a port. With the TPID value
set on a port, the port fills the value to the TPID field of the outer tag to be added for a
packet and, upon receiving a packet, compares the TPID value with the TPID field of
the packet to determine whether the packet carries a VLAN tag or not.
Use the undo vlan-vpn tpid command to restore the default TPID value.
The default TPID value is 0x8100.
For the position and function of the TPID field in a packet, refer to VLAN Operation.
The TPID field in an Ethernet frame has the same position with the protocol type field in
a frame without a VLAN tag. To prevent other devices in the network from recognizing
the tag-encapsulated packets of the current switch as protocol packets, you are not
allowed to set the TPID value to any of the values in the table below.

dest-vlan-id
undo mac-address-mapping { index | all }
View
Ethernet port view
Parameters
index: Index of the inter-VLAN MAC address replicating configuration to be created or
removed. This argument is in the range 0 to 7.
source-vlan source-vlan-list: Specifies a list of the IDs of the VLANs, whose MAC
address entries are to be replicated to the MAC address table of the destination VLAN.
You need to provide the source-vlan-list argument in the form of { vlan-id [ to
vlan-id ] }&<1-10>, where the VLAN ID after the to keyword must be larger than or
equal to the VLAN ID before the to keyword and &<1-10> means that you can specify
up to 10 VLANs/VLAN ranges for this argument.
dest-vlan-id: ID of the destination VLAN for replication, in the range 1 to 4094.
all: Removes all the inter-VLAN MAC address replicating configurations created on the
current port.
Description
Use the mac-address-mapping command to configure the inter-VLAN MAC address
replicating feature for a port. This feature can replicate MAC address entries of the
Command Manual – VLAN-VPN
H3C S3100-52P Ethernet Switch Chapter 2 Selective QinQ Configuration Commands
2-2
MAC address tables of specified source VLANs to the MAC address table of the
specified destination VLAN.
Use the undo mac-address-mapping command to disable this feature.
The inter-VLAN MAC address replicating feature is disabled on any port by default.
In a selective QinQ application, you can configure this feature to:
z Replicate MAC address entries in the MAC address tables of the outer VLANs
configured in selective QinQ to the MAC address table of the default VLAN of the
downlink port. This is for forwarding uplink packets to the operator network.
z Replicate MAC address entries in the MAC address table of the default VLAN of
the downlink port to the MAC address tables of all the outer VLANs configured in
selective QinQ. This is for forwarding packets from the operator network to the
user networks.
Examples
# Enable the inter-VLAN MAC address replicating feature for Ethernet1/0/1 to replicate
the MAC address entries between the MAC address table of VLAN 4 (the default VLAN)
and that of the outer VLAN 10.

Parameters
vlan-id-list: Lists of VLAN IDs. After receiving packets of these VLANs, the switch will
encapsulate the packets with the specified outer VLAN tag. You need to provide this
argument in the form of { vlan-id [ to vlan-id ] }&<1-10>, where the VLAN ID after the to
keyword must be larger than or equal to the VLAN ID before the to keyword and
&<1-10> means that you can specify up to 10 VLANs/VLAN ranges for this argument.

all: Removes all configurations of encapsulating an outer VLAN tag for specified inner
VLANs in the current view.
Description
Use the raw-vlan-id inbound command to specify to encapsulate packets with the
specified inner VLAN tags with the specified outer tag. This command must be
configured on ports connecting the user network.
Use the undo raw-vlan-id inbound command to remove the configuration.
By default, the switch does not encapsulate packets with any outer VLAN tag.
Caution:
A packet cannot be tagged with different outer VLAN tags. To change the outer VLAN
tag of a packet, you need to remove the existing outer VLAN tag configuration and
configure a new outer VLAN tag.
Before configuring this command in QinQ view, you need to use the vlan-vpn vid
command to configure the outer VLAN tag to be used in the selective QinQ policy.
Related commands: vlan-vpn vid.
Examples
# Configure Ethernet 1/0/1 to add the tag of VLAN 20 as the outer tag to packets with
their inner VLAN IDs being 8 through 15.

Parameters
vlan-id: VLAN ID, in the range 1 to 4094.
Description
Use the vlan-vpn vid command to configure the outer VLAN tag for a selective QinQ
policy (that is, the outer VLAN tag to be used by a port to encapsulate received packets)
and to enter QinQ view.
Use the undo vlan-vpn vid command to remove the configured outer VLAN tag. Note
that this command will also remove all configurations configured by the raw-vlan-id
inbound command in QinQ view.
Before configuring this command on a port, make sure that the vlan-vpn enable
command is configured on the port.
By default, no selective QinQ policy is configured on a port.
After specifying an outer VLAN tag and enter QinQ view, you need to use the
raw-vlan-id inbound command to specify which VLANs’ packets will be encapsulated
with the specified outer VLAN tag. Otherwise, the configuration of the outer VLAN tag is
of no use.
Related commands: raw-vlan-id inbound.
Examples
# Specify Ethernet 1/0/1 add VLAN 20 tag as the outer tag to the packets with their
inner VLAN IDs being 2 through 14.

protocol (HGMP) related protocols, including neighbor
discovery protocol (NDP), neighbor topology discovery
protocol, cluster member remote control (MRC), and Huawei
authentication bypass protocol (HABP).
lacp
Enable/Disable BPDU tunnel for link aggregation control
protocol (LACP).
pagp
Enable/Disable BPDU tunnel for port aggregation protocol
(PAGP).
Command Manual – VLAN-VPN
H3C S3100-52P Ethernet Switch Chapter 3 BPDU Tunnel Configuration Commands

Value Description
pvst
Enable/Disable BPDU tunnel for per-VLAN spanning tree
(PVST).
stp
Enable/Disable BPDU tunnel for spanning tree protocol (STP).
vtp
Enable/Disable BPDU tunnel for VLAN trunk protocol (VTP).
udld
Enable/Disable BPDU tunnel for uni-directional link direction
(UDLD).
all: Disables BPDU tunnel for all protocol packets.
Description
Use the bpdu-tunnel command to enable BPDU tunnel on a port, so that packets of the
specified protocol will be transparently transmitted through the BPDU tunnel on the
port.
Use the undo bpdu-tunnel command to disable BPDU tunnel on a port.
By default, BPDU tunnel is disabled on a port.
After you enable a port to transmit packets of a specified protocol type through the
BPDU tunnel, when the port receives such a packet, it will use the specified private
multicast MAC address to replace the original destination MAC address of the packet
before sending it. As a result, the packet will not be recognized as a protocol packet by
other devices in the operator network during transmission. In this way, transparent
transmission is implemented.
You can use the bpdu-tunnel tunnel-dmac command to change the destination MAC
addresses of protocol packets to a specified multicast MAC address.
Caution:
z If this command is enabled on a port for a specific protocol, the specific protocol
cannot be enabled on the port. For example, if you have configured the
bpdu-tunnel lacp command, the lacp enable command cannot be enabled on the
port.
z The commands configured for service provider’s devices at both ends of a BPDU
tunnel must be consistent. Otherwise, BPDU packets of the customer network
cannot be transparently transmitted properly.
Examples
# Enable BPDU tunnel for packets of LACP.

Parameters
mac-address: Destination MAC address to be assigned to the protocol packets
transmitted along a BPDU tunnel. This argument must be a multicast MAC address.
Description
Use the bpdu-tunnel tunnel-dmac command to configure the destination MAC
address for protocol packets transmitted along a BPDU tunnel.
Use the undo bpdu-tunnel tunnel-dmac command to restore the default destination
MAC address.
By default, the destination MAC address for protocol packets transmitted along a BPDU
tunnel is 010f-e200-0003.
Caution:
z To prevent the devices in the service provider network from processing the tunnel
packets as other protocol packets, the MAC address for tunnel packets must be a
multicast address specially for BPDU tunnels in the service provider network.
z The destination MAC addresses configured at the two ends of a BPDU tunnel must
be the same; otherwise, the protocol packets cannot be transmitted and forwarded
normally.
