Pete & Associates, Inc.4th Floor SwitchMarketingAccountingNotice that all the workstations are still plugged into the same single switch.But now, they are in two different broadcast domains. In other words, when aworkstation in Marketing sends a broadcast (ARP, DHCP, etc.), Accounting willnever see it, even if the two departments are in the same subnet. The VLANbehaves exactly like the solution in which you bought another switch. It's as ifthe one switch has become two smaller switches (that are not connected toeach other).Now, let's say that the Marketing department increased in size, and nowthey've moved some of their personnel up to the fifth floor. The workstationson the fifth floor plug into a different switch, which is plugged into the switchon the fourth floor.5th Floor SwitchVLAN 20 VLAN 104th Floor SwitchMarketingAccountingBrocade IP Primer 171
