Mulitcast through Desktop Switches?

    Question

  • I read that the main things you need to do to get Multicast working is check the box to enable it in MDT and save the changes to the deployment share and make sure the network supports IGMPv3 and that IGMP snooping is enabled on the switches.

    So that sounds fine, but what if there is an unmanaged desktop switch in your deployment room where the computers are physically plugged into such as a Netgear or something like this:  http://www.trendnet.com/products/proddetail.asp?prod=240_TEG-S24Dg 

    The wall jack port is connected to a managed switch in the back, but we need to share the connection by using an additional switch on the bench or we would only be able to connect one PC at a time.

    There are no IGMP settings to manage in these types of simple desktop switches, so does that mean it allows everything through and we don't need to worry about it?  I can't imagine having a huge rackmount-style switch with fans blaring in our deployment work area or installing that many unique network ports in the room.

  • Basically you'll have to try it and see. No one in this forum can give you and pointer/guarantee that it will work. From my experience it will not.

  • That's surprising to hear that no one has ever tried multicasting through an umanaged desktop switch before me.

    We have to purchase the switch, so we do not want to wait for the purchase and shipping and then experiment with it afterwards.

    I would have guessed that a simple switch would more likely allow everything through to prevent support calls and reduce product returns than be configured to block anything.  

    How are other people who are successfully using multicasting connecting all their computers to the network?

  • I have had no problems doing multicast deployment testing through my trusty NetGear GS108 switches.

    FastEthernet is too slow for me.

  • I don't mean people haven't tested or done it, I mean that there are more to it than just any unmanaged switch.

  • Since we haven't purchased the switch yet, we can choose one that is known to work instead of using trial and error as if we were the first to ever do this if people post their specific experiences with ones that work.
