华为设备配置Smart Link主备备份

1. 配置VLAN信息
   [LSW1]vlan batch 10 20 30
   [LSW1-GigabitEthernet0/0/2]port link-type trunk
   [LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20 30
   [LSW1-GigabitEthernet0/0/3]port link-type trunk
   [LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20 30
   [LSW2]vlan batch 10 20 30
   [LSW2-GigabitEthernet0/0/1]port link-type trunk
   [LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20 30
   [LSW2-GigabitEthernet0/0/4]port link-type trunk
   [LSW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 10 20 30
   [LSW3]vlan batch 10 20 30
   [LSW3-GigabitEthernet0/0/1]port link-type trunk
   [LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20 30
   [LSW3-GigabitEthernet0/0/4]port link-type trunk
   [LSW3-GigabitEthernet0/0/4]port trunk allow-pass vlan 10 20 30
   [LSW4]vlan batch 10 20 30
   [LSW4-GigabitEthernet0/0/2]port link-type trunk
   [LSW4-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20 30
   [LSW4-GigabitEthernet0/0/3]port link-type trunk
   [LSW4-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 20 30
2. 创建Smart Link备份组，并指定端口角色
   [LSW1-GigabitEthernet0/0/2]stp disable
   [LSW1-GigabitEthernet0/0/3]stp disable
   [LSW1]smart-link group 1
   [LSW1-smlk-group1]port GigabitEthernet 0/0/2 master
   [LSW1-smlk-group1]port GigabitEthernet 0/0/3 slave
3. 使能回切功能并设置回切时间
   [LSW1-smlk-group1]restore enable
   [LSW1-smlk-group1]timer wtr 30
4. 使能发送Flush报文功能
   [LSW1-smlk-group1]flush send control-vlan 10 password simple 123
5. 使能接收Flush报文功能
   [LSW2-GigabitEthernet0/0/1]smart-link flush receive control-vlan 10 password simple 123
   [LSW2-GigabitEthernet0/0/1]stp disable
   [LSW2-GigabitEthernet0/0/4]smart-link flush receive control-vlan 10 password simple 123
   [LSW2-GigabitEthernet0/0/4]stp disable
   [LSW3-GigabitEthernet0/0/1]smart-link flush receive control-vlan 10 password simple 123
   [LSW3-GigabitEthernet0/0/1]stp disable
   [LSW3-GigabitEthernet0/0/4]smart-link flush receive control-vlan 10 password simple 123
   [LSW3-GigabitEthernet0/0/4]stp disable
   [LSW4-GigabitEthernet0/0/2]smart-link flush receive control-vlan 10 password simple 123
   [LSW4-GigabitEthernet0/0/2]stp disable
   [LSW4-GigabitEthernet0/0/3]smart-link flush receive control-vlan 10 password simple 123
   [LSW4-GigabitEthernet0/0/3]stp disable
6. 使能Smart Link组功能
   [LSW1]smart-link group 1
   [LSW1-smlk-group1]smart-link enable
7. 验证配置
   

[LSW1-GigabitEthernet0/0/2]shutdown

[LSW1-GigabitEthernet0/0/2]undo shutdown
