N3048 bridge multicast

Hey there all wise folks. I'm starting to make the great migration from using the older 6248P series switches to the N3048P switches and need to do some static bridge multicast per port type stuff but have not figured out how to set that up on the N3048P as it seems many of the commands have changed. In the 6248P environment I use things like:

bridge multicast filtering

bridge multicast address 0100.5E01.0101 add ethernet 1/g1-1/g2, 1/g4

Any ideas how to do the same thing on the N3048P?

I even tried the web interface and found where to set up groups but when I try to add something that way nothing happens. Please advise

thanks

Steve
