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:

zThis feature can be enabled only on VLAN-VPN-enabled ports.

zThis command is mutually exclusive with the vlan-vpn priority command.

refer to Qos-QoS Profile Operation.

Description

Use the vlan-vpn priority command to configure the mapping between the inner VLAN

priority and the outer VLAN priority. With the mapping configured, a port will

encapsulate a packet with the specified inner tag priority with an outer tag that has the

corresponding priority.

Use the undo vlan-vpn priority command to remove the configuration.

By default, no mapping between the inner tag priority and the outer tag priority is

configured, and the switch uses 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.

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:

zReplicate 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.

zReplicate 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.
