rotocol is used on IP networks to establish multicast group
memberships. It operates above the network layer of OSI model. One of the most important features
related to this protocol is IGMP snooping, which is supported by the managed switch and greatly
strengthens network functionality.
IGMP Snooping:
It is a process of “listening” to IGMP network traffic. By listening to conversations
between different devices, it maintains a map of links and IP multicast streams. This means
multicasts may be filtered from the links which do not need them, and IGMP snooping allows the
switch to only forward multicast traffic to the links that have requested it.
