3 I NTRODUCTION This chapter describes the features of the 24-Po rt 10/100Mbps Fast Ethernet Smart S witch and some background inf ormation about Ethernet/Fast Ethernet s witching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop co mputing ap plicat ions are fuel ing the need for high perf[...]

4 Switching Technology Another approach to pus hing beyond the limits of Ethernet technology is the development of switchin g technology. A switch bridges Ethernet packets at the MAC add ress level of the Ethernet protocol transmitting amon g connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-eff ective way of increasing the tota[...]

5 VLAN (Virtual Lo cal Area Networ k) A VLAN is a group of end-stations that are not constrained by their physical location and can communicate as if in a common broadcast domain, a LAN. The primary utility of using VLAN is to reduce latency a nd need for routers, using fas ter switching instead. Other VLAN ut ility include: ¾ Security Security is[...]
