Multicast filter on SG300-10 and IGMP Querier

Hi

We're currently testing the Cisco SG300-10 for use with multicast TV services/channels but we're having trouble configuring the switch. Our setup is that we have a TV provider which is multicasting all their TV services into the switch's port 3. The multicast packets of a TV-channel should only be forwarded to another port in the switch if a client sends a IGMP join (report) message to start receiving a service.

First we've tried to disable multicast broadcasting by enabling Bridge Multicast Filtering Status (manual chap 15, "Defining Multicast Properties") but multicast packets are still broadcast on all ports. How do we filter multicast packets so they're not broadcast on all ports?

Also we need the SG300-10 switch to run as IGMP Querier so clients report membership at a regular basis. We've tried enabling IGMP Querier (manual chap. 15 "Configuring IGMP snooping") but it always remain disabled and we never see any IGMP Query messages (we use Wireshark to check this). How do we enable IGMP Querier?

When I press Apply the "IGMP Querier Status" remain "Disabled" in the "IGMP Snooping" page. Also the IP-address I specify is never transferred to the "IGMP Snooping" page.

Here's the switch's configuration:

Hm, solved multicast by filtering "Unregistered Multicast" and IGMP Querier by enabling IGMP snooping.
