IGMP snooping avoids ports to be flooded with undesired multicast packets.\
It is a smart way to manage multicast packets, and forward them to the registered ports.

IGMP snooping is disabled by default.

2. Click in the **IGMP Snooping column**, that box you want to enable or disable.
3. Click **Apply settings and stay where you are** or **Apply settings and leave edit**.

IGMP snooping is enabled or disabled for the selected group, and saved in the startup configuration.
