3 配置步骤
3.1 进入SW1的命令行，全局下开启IGMP Snooping功能
System View: return to User View with Ctrl+Z..
[H3C] igmp-snooping
[H3C-igmp-snooping] quit
3.2 在VLAN 1内使能IGMP Snooping，并使能IGMP Snooping查询器
[H3C]vlan 1
[H3C-vlan1]igmp-snooping enable
[H3C-vlan1]igmp-snooping querier
3.3 保存配置
[H3C]save force
3.4 进入SW2的命令行，全局和VLAN1下都开启IGMP Snooping功能
System View: return to User View with Ctrl+Z.
[H3C] igmp-snooping
[H3C]vlan 1
[H3C-vlan1]igmp-snooping enable
