When Host A leaves the multicast group, it sends an IGMP leave message to Switch A. Receiving the
message, Switch A removes port GigabitEthernet 1/0/4 from the member port list of the forwarding
entry for the group; however, it does not remove the group or forward the leave message to Router A
because Host B is still in the group. Use the display igmp-snooping group command to display
information about IGMP snooping groups. For example:
# Display information about IGMP snooping groups on Switch A.
[SwitchA] display igmp-snooping group

Multicast source and user control policy configuration example
Network requirements
As shown in Figure 18, Switch A is a Layer-3 switch. Switch A runs IGMPv2 and Switch B runs IGMPv2
snooping. Multicast sources and hosts run 802.1X client.
A multicast source control policy is configured on Switch A to block multicast flows from Source 2 to
224 .1.1.1.
