Not exactly. It was about a specific vlan.
I'm thinking it might be a better way to block multicast traffic on port with the help of disable multicast flooding, ingress rate-limiting or something like that.

You could create a Policy that tells the port to drop Multicast traffic, but why would you want to? A lot of essential network services, Routing Protocols (OSPF, RIP, etc), network services like DHCP, IGMP, VRRP, Link-local name resolution, video and audio conferencing rely on Multicast traffic to efficiently get packets around your network. And if configured rightly, Multicast traffic can potentially only account for a fraction of network traffic

We decided to do it because we find strange multicast activity in our network. We are going to block all multicast traffic from particular segments for diagnostic.
