Chapter 2 Overview The 7200 Series Managed Switch software has two purposes: • Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information contained in the frames. • Provide a complete device management portfolio to the network administrator. 2.1 Scope 7200 Series Managed Switch software encompasses both hardware and software support. It software is partitioned to run in the following processors: • CPU-This code runs the networking device management portfolio and controls the overall networking device hardware. It also assists in frame forwarding, as needed and specified. This code is designed to run on multiple platforms with minimal changes from platform to platform. • Networking Device Processor-This code does the majority of the packet switching, usually at wire speed. This code is platform dependent, and substantial changes might exist across products. 2.2 Product Concept Fast Ethernet and Gigabit Ethernet switching continues to evolve from high-end backbone applications to desktop switching applications. The price of the technology continues to decline, while performance and feature sets continue to improve. Devices that are capable of switching Layers 2, 3, and 4 are increasingly in demand. 7200 Series Managed Switch software provides a flexible solution to these ever-increasing needs. The exact functionality provided by each networking device on which the 7200 Series Managed Switch software base runs varies depending upon the platform and requirements of NETGEAR.
