# Enable IGMP snooping globally.
<SwitchA> system-view
[SwitchA] igmp-snooping
[SwitchA-igmp-snooping] quit
# Create VLAN 100, assign ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/4 to this
VLAN, and enable IGMP snooping and IGMP snooping proxying in the VLAN.
[SwitchA] vlan 100
[SwitchA-vlan100] port gigabitethernet 1/0/1 to gigabitethernet 1/0/4
[SwitchA-vlan100] igmp-snooping enable
[SwitchA-vlan100] igmp-snooping proxying enable
[SwitchA-vlan100] quit
Verifying the configuration
After the configuration is completed, Host A and Host B send IGMP join messages for group 224.1.1.1.
Receiving the messages, Switch A sends a join message for the group out of port GigabitEthernet 1/0/1
(a router port) to Router A.
Use the display igmp-snooping group command and the display igmp group command to display
information about IGMP snooping groups and IGMP multicast groups. For example:
# Display information about IGMP snooping groups on Switch A.
[SwitchA] display igmp-snooping group
