I think she tried it (see config at the end) and it didn't work. I also think btw that storm control is an inbound feature so it's probably not what's needed here. I briefly looked at the documentation and my impression is that 'switchport block multicast' is the command that would solve exactly this problem (ie. preventing mcast packets to be sent). However she seems to have tried that, too, so I am not sure what to say. If nothing else helps, then configuring the 3550 as a router might be an option. But I am really curious why blocking didn't do the trick. Thanks, Zsombor >-rajesh > > >TP wrote: > > > Dear Group, > > > > I need help about multiscast. > > This is a simple topology...
