Introduction DES-3226 Series Intelligent Ethernet Switch This guide discusses how to manage the DES-3226 Series switch using the D-View5.1 network management system. The DES-3226 Series combines conventional Ethernet, Fast Ethernet, Gigabit Ethernet, and switching technologies into one package. This device features twenty-four 10/100 NWay switching ports, and supports an optional ultra high-speed 1000BASE-SX Gigabit Ethernet rear module. Additional information about configuring the DES-3226 Ethernet switch may be found in the Ethernet switch's hardware User's Guide. Network Management As networks grow larger, network management becomes more and more of a necessity. A large network requires a considerable amount of work to keep it running smoothly, including time and effort spent on user support, troubleshooting, network planning, and performance monitoring. The intent of a network management system (NMS) is to make it possible to monitor a widely spread-out network (possibly spanning many different sites) from a centralized location. Network management works by placing a small degree of "intelligence" in the network elements (routers, switches, hubs, hosts, etc.) to be managed. This intelligence takes the form of an agent that is capable of collecting statistics and status information, as well as performing control operations that affect the operation of the network. The agent responds to commands and requests for information from the centralized network management system, allowing the health and performance of the network to be monitored and adjusted.

Introduction
DES-3226 Series Intelligent Ethernet Switch
This guide discusses how to manage the DES-3226 Series switch using the
D-View5.1 network management system. The DES-3226 Series combines
conventional Ethernet, Fast Ethernet, Gigabit Ethernet, and switching
technologies into one package. This device features twenty-four 10/100 NWay
switching ports, and supports an optional ultra high-speed 1000BASE-SX
Gigabit Ethernet rear module.
Additional information about configuring the DES-3226 Ethernet switch may
be found in the Ethernet switch’s hardware
User’s Guide

Network Management
As networks grow larger, network management becomes more and more of a
necessity.
A large network requires a considerable amount of work to keep it
running smoothly, including time and effort spent on user support,
troubleshooting, network planning, and performance monitoring.
The intent of
a network management system (NMS) is to make it possible to monitor a widely
spread-out network (possibly spanning many different sites) from a centralized
location.
Network management works by placing a small degree of “intelligence” in the
network elements (routers, switches, hubs, hosts, etc.) to be managed.
This
intelligence takes the form of an
agent
that is capable of collecting statistics and
status information, as well as performing control operations that affect the
operation of the network.
The agent responds to commands and requests for
information from the centralized network management system, allowing the
health and performance of the network to be monitored and adjusted.
