What is IGMP?

IGMP (Internet Group Management Protocol) is a network protocol used to manage multicast group membership on IPv4 networks. It allows devices to join or leave multicast groups, ensuring that multicast traffic is only sent to devices that need it. On Maple Systems network switches, IGMP helps optimize network performance by preventing unnecessary multicast traffic from overwhelming network bandwidth. This is especially useful for applications like video streaming, industrial automation, and real-time data distribution.

IGMP Snooping is a feature that enhances IGMP by allowing switches to monitor and control multicast traffic at the data link layer. Instead of forwarding multicast traffic to all ports, the IGMP Snooping ensures that multicast data is only sent to the ports with registered group members. This reduces network congestion and improves efficiency by preventing unnecessary multicast flooding. On Maple Systems switches, enabling IGMP Snooping helps maintain optimal network performance, especially in environments with high multicast traffic.
