    Introduction Chapter 4, Using FN100 Trunking, details using the FN100 Port Trunking window to create trunk groups, allowing you to increase aggregate bandwidth when two or more switches are connected. Chapter 5, Workgroup Configuration, describes configuring work groups by specifying a subset of device ports and the type(s) of packets (multicast, unicast, or both) that are to be forwarded by those ports, thereby allowing you to restrict multicast traffic from being propagated through every bridge port on your device.
