Figure 8-2 IGMP Example 1Example 2: Select an IGMP Server Manually

To force Switch A to be the IGMP server, select Enable in the IGMP Query Mode field. However if another multicast device is set to Auto and it has a numerically lower IP address, it will act as the IGMP server also. This results in duplicated IGMP messages that might decrease your network performance.

Unless you can disable IGMP on the other multicast devices on your network, it is not recommended you select the Enable option.
