Chapter 2 Multicast Protocol
Configuration Examples
2-18
[SwitchB] vlan 100
[SwitchB-vlan100] port Ethernet 1/0/1 to Ethernet 1/0/3
[SwitchB-vlan100] igmp-snooping enable
[SwitchB-vlan100] quit
III. Configuring Switch C
# Enable IGMP Snooping globally.
<SwitchC system-view
[SwitchC] igmp-snooping enable
Enable IGMP-Snooping ok.
# Create VLAN 100, add Ethernet 1/0/1 through Ethernet 1/0/3 into VLAN 100, and
then enable IGMP Snooping in this VLAN.
[SwitchC] vlan 100
[SwitchC-vlan100] port Ethernet 1/0/1 to Ethernet 1/0/3
[SwitchC-vlan100] igmp-snooping enable
Caution:
Switch C is not the IGMP Snooping querier, so it does not have forwarding entries for
non-directly-connected multicast receivers, and floods multicast packets for such
receivers within the VLAN to which the packets belong. Therefore, to avoid impact on
the network and on Switch C caused by multicast flooding, it is recommended to enable
IGMP Snooping querier on the switch that is as close to the multicast source as
possible.
IV. Verifying the configuration
1) View information on Switch B.
# View IGMP packet statistics on Switch B.
<SwitchB> display igmp-snooping statistics

Received IGMP V2 report packet(s) number:53.
Received IGMP leave packet(s) number:1.
Received error IGMP packet(s) number:0.
Sent IGMP specific query packet(s) number:1.
Switch B received IGMP general queries sent by the querier and IGMP reports from
