Chapter 1. IntroductionThis chapter briefly describes the functions, capabilities, and benefits of the 8275Model 416 High Performance Ethernet Workgroup Switch. This information helpsyou to plan for and use the 8275-416 in your network.Product OverviewFast Ethernet switching continues to evolve from high-end backbone applications todesktop switching applications. The 8275-416 provides a low cost and powerfulLayer 2 switch solution. It is an attractive base switch offering with the following keyfunctions:v High performance, Layer 2, managed switchv 16 base ports (10/100BASE-TX), expandable to 24 or 32 ports. The expansioncan be any combination of the following optional feature modules:– 8-Port 10/100BASE-TX– 8-Port 100BASE-FXv Robust management support; VT100 terminal interface, Web interface, SNMPv Backplane performance 10 Giga-bits per second Ethernet switchingv Desktop and segment switching infrastructurev Affordable migration to higher performance networksNetwork administrators have a choice of three easy-to-use management methods:VT100 interface, Web-based, and Simple Network Management Protocol (SNMP).These management methods enable the network administrator to configure,manage, and control the 8275-416 locally or from anywhere on the network.The Spanning Tree Protocol (STP) provides fault tolerance on the network.8275-416 FunctionsThis section describes the functional support included in the 8275-416 :v Layer 2 switchingv Management and user interfacev Securityv Reliability and serviceabilityv Performancev Flow Controlv Y2KLayer 2 SwitchingThe 8275-416 is a frame-based Layer 2 Ethernet switch. In a Layer 2 switch, frameforwarding is based on MAC addresses. The 8275-416 supports the IEEE P802.1D(1990) standard.© Copyright IBM Corp. 1999 1
