FX-16NW

Broadcast Domain

Although a collision domain is divided by each of the ports on the Switch, a

broadcast packet is still sent to all ports, regardless of collision domain

d i fferences. The portion of a network that receives a broadcast packet is

called a “broadcast domain”. Normally, a router is used to divide one

broadcast domain into multiple domains.

itself; there is no need to obtain expensive routers to do the job.

Each of the sixteen switch ports on the FX-16NW Switching Hub can be

assigned to multiple VLAN groups, and up to 16 groups can be created in

the Switch. For a specific procedure to assign each port to a VLAN, please

refer to Chapter 3.

Broadcast Packet

This is the packet that is received by all devices on a network. VLAN and

routers can modify how this packet is sent to nodes in a given network.

Collision Domain

In a network that employs repeater hubs, a collision of packets may take

place when two or more devices on the network transmit a packet at the

same time. The portion of a network that shares the same collision signal is

called a “collision domain”. In a switching hub, each port is assigned to a

separate collision domain. (In other words, a collision domain is divided

into multiple smaller collision domains.) In addition, certain limitations on

node-to-node distance and cascade connection apply to nodes within the

same collision domain.
