I think that entirely depends upon the placement of the sniffing points.  If you sniff on a network without placing at an egress or ingress point, you will see multicast/broadcast traffic that you happen to see, but not much more of interest.

Is your sniffing interface placed well to monitor traffic of interest to you?  What spanning/mirroring technology are you using?
