In networks where multimedia applications generate multicast traffic, Internet Group Multicast 
Protocol (IGMP) can greatly reduce unnecessary bandwidth usage by limiting traffic forwarding 
that is otherwise broadcast to the whole network. Enabling IGMP will allow individual ports to 
detect IGMP queries, report packets, and manage IP multicast traffic through the switch.

•

Enable. The system will detect IGMP queries, report packets, and manage IP multicast traffic 
through the switch

•

Disable. The switch will forward traffic and disregard any IGMP requests.

Use this menu to configure permanently reachable multicast groups.
