Chapter 1. Introduction
This chapter briefly describes the functions, capabilities, and benefits of the 8275
Model 416 High Performance Ethernet Workgroup Switch. This information helps
you to plan for and use the switch in your network.
Product overview
Fast Ethernet switching continues to evolve from high-end backbone applications to
desktop-switching applications. The switch provides a low-cost and powerful Layer
2 switch solution. It is an attractive base switch offering with the following key
functions:
v
High-performance, Layer 2, managed switch
v
16 base ports (10/100BASE-TX), expandable from 18 to 32 ports, depending on
the combination of the following optional feature modules:
– 8-Port 10/100BASE-TX
– 8-Port 100BASE-FX
– 4-Port 100BASE-FX
– 2-Port 1000BASE-SX
v
Robust management support; VT100 terminal interface, Web interface, SNMP
v
Backplane performance 10 gigabits per second Ethernet switching
v
Desktop and segment switching infrastructure
v
Affordable migration to higher-performance networks
As a network administrator, you have a choice of three easy-to-use management
methods: VT100 terminal interface, Web-based, and Simple Network Management
Protocol (SNMP). These management methods enable you to configure, manage,
and control the switch locally or from anywhere on the network.
The Spanning Tree Protocol (STP) provides fault tolerance on the network.

Layer 2 switching
The 8275-416 is a Layer 2 Ethernet switch in which frame forwarding is based on
MAC addresses and VLAN membership. The switch supports the IEEE 802.1D
(1998) and 802.1Q standards.
