[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

System View: return to User View with Ctrl+Z.

[H3C] igmp-snooping
