How to Configure Huawei Switch Common VLAN Mapping?

Configuring 1 to 1 VLAN Mapping

1 to 1 VLAN mapping allows the switch to map the VLAN ID of packets to an S-VLAN ID.

For example, configure the switch to map VLAN 2 in packets entering GE0/0/1 to VLAN 200.

<HUAWEI> system-view

[HUAWEI] interface gigabitethernet0/0/1

[HUAWEI-GigabitEthernet0/0/1] port link-type trunk  //Configure the interface as a trunk interface. VLAN mapping can only be configured on a trunk or hybrid interface.

[HUAWEI-GigabitEthernet0/0/1] qinq vlan-translation enable  //On a fixed device, VLAN translation must be enabled first. This configuration is not required on a modular device.

[HUAWEI-GigabitEthernet0/0/1] port vlan-mapping vlan 2 map-vlan 200

Configuring N to 1 VLAN Mapping

N to 1 VLAN mapping allows the switch to map a range of VLAN IDs to an S-VLAN ID.

For example, configure the switch to map VLANs 3, 4, 5, and 6 in packets entering GE0/0/1 to VLAN 200.

<HUAWEI> system-view

[HUAWEI] interface gigabitethernet0/0/1

[HUAWEI-GigabitEthernet0/0/1] port link-type trunk  //Configure the interface as a trunk interface. VLAN mapping can only be configured on a trunk or hybrid interface.

[HUAWEI-GigabitEthernet0/0/1] qinq vlan-translation enable  //On a fixed device, VLAN translation must be enabled first. This configuration is not required on a modular device.

[HUAWEI-GigabitEthernet0/0/1] port vlan-mapping vlan 3 to 6 map-vlan 200

 NOTE:

This configuration is not supported by Huawei S5720HI, S5730HI, and S6720HI.

Configuring 2 to 1 VLAN Mapping

When an interface configured with 2 to 1 VLAN mapping receives a double-tagged packet, it maps the outer tag of the packet to the S-VLAN tag and transparently transmits the inner tag as the data.

For example, configure the switch to map the outer VLAN ID of 8 and inner VLAN ID of 7 in packets entering GE0/0/1 to the outer VLAN ID of 200 and to retain the inner VLAN ID.

<HUAWEI> system-view

[HUAWEI] interface gigabitethernet0/0/1

[HUAWEI-GigabitEthernet0/0/1] port link-type trunk  //Configure the interface as a trunk interface. VLAN mapping can only be configured on a trunk or hybrid interface.

[HUAWEI-GigabitEthernet0/0/1] qinq vlan-translation enable  //On a fixed device, VLAN translation must be enabled first. This configuration is not required on a modular device.

[HUAWEI-GigabitEthernet0/0/1] port vlan-mapping vlan 8 inner-vlan 7 map-vlan 200

 NOTE:

Only the S1720X, S1720X-E, S3700HI, S5700EI, S5700HI, S5710EI, S5710HI, S5720EI, S5720HI, S5730HI, S5730S-EI, S5730SI, S6700EI, S6720EI, S6720HI, S6720LI, S6720S-EI, S6720S-LI, S6720S-SI, and S6720SI of fixed devices support this configuration. The modular device supports this configuration.

Configuring 2 to 2 VLAN Mapping

When an interface configured with 2 to 2 VLAN mapping receives a double-tagged packet, it maps double tags of the packet to S-VLAN tags.

For example, configure the switch to map the outer VLAN ID of 11 and inner VLAN ID of 10 in packets entering GE0/0/1 to the outer VLAN ID of 200 and inner VLAN ID of 201.

<HUAWEI> system-view

[HUAWEI] interface gigabitethernet0/0/1

[HUAWEI-GigabitEthernet0/0/1] port link-type trunk  //Configure the interface as a trunk interface. VLAN mapping can only be configured on a trunk or hybrid interface.

[HUAWEI-GigabitEthernet0/0/1] qinq vlan-translation enable  //On a fixed device, VLAN translation must be enabled first. This configuration is not required on a modular device.

[HUAWEI-GigabitEthernet0/0/1] port vlan-mapping vlan 11 inner-vlan 10 map-vlan 200 map-inner-vlan 201

 NOTE:

Only the S1720X, S1720X-E, S5720EI, S5720HI, S5730HI, S5730S-EI, S5730SI, S6720EI, S6720HI, S6720LI, S6720S-EI, S6720S-LI, S6720S-SI, and S6720SI of fixed devices support this configuration. The modular device supports this configuration.

Traffic Policy Failed in Huawei S6720 Switch

Issue Description

Customer feedback that the traffic policy apply fail in Huawei S6720 200R009C00SPC500, and want to know the reason.

Handling Process

Step 1 check the traffic policy configuration as follow:

traffic behavior af1
 remark 8021p 1
#
traffic classifier match-any operator or
 if-match any
#
traffic policy af1 match-order config
 classifier match-any behavior af1
#

Step 2 check the port configuration as follow:

interface XGigabitEthernet0/0/2.1709
 mtu 1600
 qinq mapping vid 1710 map-vlan vid 1709
 traffic-policy af1 inbound
 mpls l2vc 10.3.1.4 152 tunnel-policy T1

Root Cause

The traffic behavior Remark 8021p and qinq mapping vid 1710 map-vlan vid 1709 conflict,It cause the fail.

Solution

The traffic behavior Remark 8021p and qinq mapping vid 1710 map-vlan vid 1709 both opreation for vlan, so it will conflict and cause the fail.

So we suggest customer change the traffic behavior for example remark dscp or others behavior

Suggestions

The conflict operation may cause the traffic policy fail. Before configuration suggest check our production document there have the detail limit description.
