IGMP Snooping IGMP specifies how a host can register to a router in order to receive specific multicast traffic. Configure the switch to use IGMP snooping in subnets that receive IGMP queries from either IGMP or the IGMP snooping querier. IGMP snooping constrains multicast traffic at Layer 2 by configuring Layer 2 LAN ports dynamically to forward multicast traffic only to those ports that want to receive it. IGMP is a standard defined in RFC1112 for IGMPv1 and in RFC2236 for IGMPv2. 1. Click IGMP Snooping in the blue navigation panel. A screen similar to that shown below appears. . Figure 4-48 2.
