How to configure IGMP Snooping for Cisco 3570 switches?

Asked by Ericn84 in Network Design & Methodology, Network Switches & Hubs, Network Operations

Tags: Cisco, Switch, 3570, IGMP Snooping

Hello, I working in an environment that has its own seperate network. The network consists of several Cisco 3750 switches. The network also has some devices on it that send out Multicast traffic. We want to limit these multicasts from broadcasting throughout the isolated network.

I know that IGMP snooping is enabled by default on the switches but the problem I run into is getting a IGMP Querier configured. Because at the moment, I do not see the devices sending out Multicast traffic joining a IGMP group, instead its broadcasting everywhere. So IGMP snooping does not seem to be working properly.

Everything that I found so far requires either a Cisco router or a Cisco 65xx+ switch to be configured as the querier. Is it possible to setup IGMP snooping properly on this isolated network without needing a router or 65xx series switch? And if so, what command would I need to configure and would it only need to be configured on one switch or all switches.
