MULTICASTING Using IGMP - SETUP Layer 2 Only

[Scouseralph]

Ref - 3com 4800G 48 port 3CRS48G

I am trying to setup a simple Multicast for the first time using 5 seperate 4800G switches on Layer 2 only as traffic is streaming TV Channels internally from a server.

It works when PC is connected directly to the same switch as the media server, although when I connect another pc to an alternative switch I get a blank screen. (using VLC Player).

In addition to this I connect the various switches using a 10Gig card on the back daisy chained. (No Loop back to first switch).

So Far I have setup up numerous configuration but basically I have setup as follows.

Multicast Routing on all switches

IGMP on all switches

Main switch 1 (media server attached) - IGMP Querier

Switch 2 - IGMP Snooping

Switch 3 - IGMP Snooping

Switch 4 - IGMP Snooping

Lastly I have created a static router port Vlan1 on each 10gig card back up the switches to the Main switch. (there is only 1 vlan) and No layer 3 router.

i have made no changes to the actual port from the media server

Any assistance would be much appreciated, as I'm at a loss now.  thought this was a simple procedure.

Thanks in advance.
