1. 创建VLAN并将接口加入VLAN
[LSW1]vlan batch 10
[LSW1-GigabitEthernet0/0/1]port link-type hybrid
[LSW1-GigabitEthernet0/0/1]port hybrid untagged vlan 10
[LSW1-GigabitEthernet0/0/1]port hybrid pvid vlan 10
[LSW1-GigabitEthernet0/0/2]port link-type hybrid
[LSW1-GigabitEthernet0/0/2]port hybrid untagged vlan 10
[LSW1-GigabitEthernet0/0/2]port hybrid pvid vlan 10
[LSW1-GigabitEthernet0/0/3]port link-type hybrid
[LSW1-GigabitEthernet0/0/3]port hybrid pvid vlan 10
[LSW1-GigabitEthernet0/0/3]port hybrid untagged vlan 10
[LSW2]vlan batch 10
[LSW2-GigabitEthernet0/0/1]port link-type hybrid
[LSW2-GigabitEthernet0/0/1]port hybrid untagged vlan 10
[LSW2-GigabitEthernet0/0/1]port hybrid pvid vlan 10
[LSW2-GigabitEthernet0/0/2]port link-type hybrid
[LSW2-GigabitEthernet0/0/2]port hybrid pvid vlan 10
[LSW2-GigabitEthernet0/0/2]port hybrid untagged vlan 10
[LSW2-GigabitEthernet0/0/3]port link-type hybrid
[LSW2-GigabitEthernet0/0/3]port hybrid untagged vlan 10
[LSW2-GigabitEthernet0/0/3]port hybrid pvid vlan 10
[LSW3]vlan batch 10
[LSW3-GigabitEthernet0/0/1]port link-type hybrid
[LSW3-GigabitEthernet0/0/1]port hybrid untagged vlan 10
[LSW3-GigabitEthernet0/0/1]port hybrid pvid vlan 10
[LSW3-GigabitEthernet0/0/2]port link-type hybrid
[LSW3-GigabitEthernet0/0/2]port hybrid pvid vlan 10
[LSW3-GigabitEthernet0/0/2]port hybrid untagged vlan 10
[LSW3-GigabitEthernet0/0/4]port link-type hybrid
[LSW3-GigabitEthernet0/0/4]port hybrid untagged vlan 10
[LSW3-GigabitEthernet0/0/4]port hybrid pvid vlan 10
[LSW4]vlan batch 10
[LSW4-GigabitEthernet0/0/1]port link-type hybrid
[LSW4-GigabitEthernet0/0/1]port hybrid untagged vlan 10
[LSW4-GigabitEthernet0/0/1]port hybrid pvid vlan 10
[LSW4-GigabitEthernet0/0/3]port link-type hybrid
[LSW4-GigabitEthernet0/0/3]port hybrid pvid vlan 10
[LSW4-GigabitEthernet0/0/3]port hybrid untagged vlan 10
2. 使能全局和VLAN的IGMP Snooping功能
[LSW1]igmp-snooping enable
[LSW1]vlan 10
[LSW1-vlan10]igmp-snooping enable
[LSW2]igmp-snooping enable
[LSW2]vlan 10
[LSW2-vlan10]igmp-snooping enable
[LSW3]igmp-snooping enable
[LSW3]vlan 10
[LSW3-vlan10]igmp-snooping enable
[LSW4]igmp-snooping enable
[LSW4]vlan 10
[LSW4-vlan10]igmp-snooping enable
3. 配置LSW1为查询器
[LSW1-vlan10]igmp-snooping querier enable
4. 使能丢弃未知组播报文功能
[LSW1-vlan10]multicast drop-unknown
[LSW2-vlan10]multicast drop-unknown
[LSW3-vlan10]multicast drop-unknown
[LSW4-vlan10]multicast drop-unknown
5. 验证配置
