The example shows administrators how to configure IGMP Snooping for multicast clients and steaming servers in the same VLAN. When MediaServer multicasts the stream, IGMP snooping allows the switch to learn multicast groups without having the user to manually configure the each switch. This prevents the switch from flooding multicast streams on ports that have no members for these multicast addresses.

Note:

All network IP addresses and subnet masks are used as examples in this article. Please replace them with your actual network IP addresses and subnet masks.

1. Configure Switch

1-1. Configure the VLAN 10 on Switch.

1-2. Configure the IGMP Snooping: Enter the web GUI and go to Menu > Advanced Application > Multicast > IPv4 Multicast > IGMP Snooping. Check the “Active” box and select Unknown Multicast Frame as Drop. Check Querier. Click “Apply”. 

2. Test the Result

2-1. Play the stream on MediaServer using Multicast IP address 239.1.1.1.

2-2. Have PC send an IGMP join message for 239.1.1.1.

2-3. Go to Menu > Advanced Application > Multicast > IPv4 Multicast. PC connected to port 2 joins Multicast Group-239.1.1.1.
