The following example shows how to configure VLAN 5 as the multicast VLAN, and set port
1/0/5 as the static router port:
Switch#configure
Switch(config)#ip igmp snooping
Switch(config)#ip igmp snooping multi-vlan-config 5 rport interface gigabitEthernet
1/0/5
Switch(config)#show ip igmp snooping multi-vlan
Multicast Vlan:Enable
Vlan Id: 5
Router Time:300
Member Time:260
Replace Source IP:0.0.0.0
Static Router Port:Gi1/0/5
Dynamic Router Port:None
Forbidden Router Port:None
Switch(config)#end
Switch#copy running-config startup-config
