This is a new area for me.  Tried typing multicast in the display filter area and that didn't work.
Can you tell me what I should type ?

There are 'display filter' aliases for 'multicast' and 'broadcast'
that I sometimes use to exclude that traffic.

I don't know how that translates to a capture filter but maybe that
will give you somewhere to look.
