Vlan Mapping：vlan标签转换、vlan翻译
网络拓扑图：
需求：在SW2将客户端发来的vlan30~33数据全部转换成vlan 100从G0/0/1口往上发出
SW1配置：
<Huawei>system-view [Huawei]undo info-center enable [Huawei]sysname sw1 [sw1]vlan batch 30 31 [sw1]interface Ethernet0/0/2 [sw1-Ethernet0/0/2]port default vlan 30 [sw1-Ethernet0/0/2]inter eth0/0/3 [sw1-Ethernet0/0/3]port link-type access [sw1-Ethernet0/0/3]port default vlan 31 [sw1-Ethernet0/0/3]inter eth0/0/1 [sw1-Ethernet0/0/1]port link-type trunk [sw1-Ethernet0/0/1]port trunk allow-pass vlan 30 31
SW2：
<Huawei>system-view [Huawei]undo info-center enable [Huawei]sysname sw1 [sw2]vlan batch 32 33 [sw2]interface Ethernet0/0/2 [sw2-Ethernet0/0/2]port default vlan 32 [sw2-Ethernet0/0/2]inter eth0/0/3 [sw2-Ethernet0/0/3]port link-type access [sw2-Ethernet0/0/3]port default vlan 33 [sw2-Ethernet0/0/3]inter eth0/0/1 [sw2-Ethernet0/0/1]port link-type trunk [sw2-Ethernet0/0/1]port trunk allow-pass vlan 32 33
SW4：
<Huawei>system-view [Huawei]undo info-center enable [Huawei]sysname sw4 [sw4]vlan 100 [sw4-vlan100]quit [sw4]interface GigabitEthernet 0/0/1 [sw4-GigabitEthernet0/0/1]port link-type trunk [sw4-GigabitEthernet0/0/1]port trunk allow-pass vlan 100
SW3配置：
<Huawei>system-view [Huawei]undo info-center enable [Huawei]sysname sw3 [sw3]vlan batch 30 to 33 100 [sw3]interface GigabitEthernet 0/0/2 [sw3-GigabitEthernet0/0/2]port link-type trunk [sw3-GigabitEthernet0/0/2]port trunk allow-pass vlan 30 31 [sw3-GigabitEthernet0/0/2]inter gig0/0/3 [sw3-GigabitEthernet0/0/3]port link-type trunk [sw3-GigabitEthernet0/0/3]port trunk allow-pass vlan 32 33 [sw3-GigabitEthernet0/0/3]inter gig0/0/1 [sw3-GigabitEthernet0/0/1]port link-type trunk [sw3-GigabitEthernet0/0/1]port trunk allow-pass vlan 100 [sw3-GigabitEthernet0/0/1]qinq vlan-translation enable #开启vlan标签转换 [sw3-GigabitEthernet0/0/1]port vlan-mapping vlan 30 to 33 map-vlan 100 #将vlan30~33的标签转换成vlan 100
注：因模拟器bug，实验无法验证
