Okay, was posed with the need to Isolate multicast traffic to prevent hosts from communicating with each other. Yes they will be on different vlans and on the same switch, but the end devices will need to still communicate within the same network. The training program that we are using will be used at the exact same time on different devices and vlans. The problem with doing this, these programs will intercept each other's messages and that needs to be prevented. The two Vlans will be connected to a layer 2 switch, routed through a layer 3 switch. I explained this the best that I can. I operate on a closed network and therefore there is no need to communicate with others outside of this network. Just inside the network, but no with each other. Also, these are VMs running inside of windows machines. I just need to vlans to ignore each other's traffic.
Thanks

how about implementing VACL ?

Understand strome control block the whole thing, and your goal will be achieved with that.
Another way if you have 2 different multicast group each site, you can also have ACL to filter those multicast IP to deny from other VLAN
So each VLAN still can run their own training program, others can not join.

Hello,
not sure I fully understand what you are trying to achieve, but if you configure:
storm-control multicast level 0.0
on a switchport, all multicast traffic on that port will be suppressed...

Trying to prevent multicast traffic for one vlan from receiving multicast traffic on another vlan.
Have you ever used this storm control command before? Will it put my ports into err-disabled?

Didn’t address the issue today, had other network problems to work on. Will let you know next week. Thanks for responding.

Sorry for the late reply. Multicast routing is enabled within our network. We only want multicast traffic to circulate within one vlan, without removing this vlan or the switch from the network. I hope that explains what I am trying to do. I have several options to test during our predeployment phase so I will let everyone know how things go.
