L2 Features > IGMP Snooping
With Internet Group Management Protocol (IGMP) snooping, the EasySmart Switch can make intelligent
multicast forwarding decisions by examining the contents of each frame’s Layer 2 MAC header.
By default, IGMP is disabled. If enabled, the EasySmart switch can recognize IGMP queries and reports sent
between network stations or devices and an IGMP host. With IGMP snooping enabled, the EasySmart switch
will forward multicast traffic only to the connections that have members attached.
