Preface

About This Guide

This guide provides a general overview of CoreWatch and provides procedures for using

that application to configure and monitor a SmartSwitch Router (SSR). For product

information not available in this guide, see the manuals listed in “Related

Documentation” on page 17.

Who Should Read This Manual?

Read this manual if you are responsible for configuring or monitoring the SSR and you want to do

so using CoreWatch rather than using Command Line Interface (CLI) commands.

A Look at

CoreWatch

Cabletron Systems’ CoreWatch is a comprehensive, easy-to-use, device management and

configuration application for SmartSwitch Routers (SSRs). Based on Java Programming

Language, CoreWatch provides configuration, monitoring, and reporting capabilities with

the assistance of wizards, property sheets, and drag-and-drop operations.

CoreWatch provides access to Configuration Expert, a utility that makes tasks such as

configuring routers, virtual local area networks (VLANs), application-level Quality of

Service (QoS) policies, and security filters simple and easy.

You can run CoreWatch in the Solaris, Windows NT, or Windows 95 environments.

This chapter

• Summarizes the features of CoreWatch

• Describes the system requirements of CoreWatch

• Provides an overview of CoreWatch capabilities

• Discusses the different modes of CoreWatch

• Provides a list of the Management Information Bases (MIBs) CoreWatch supports

What Are CoreWatchs Features?

CoreWatch management features include the following:

• Java-based graphical user interface (GUI).

• Simplified bridging configuration.

• Simplified routing configuration.

• Quality of Service (QoS) policy management.

QoS is a set of parameters that assign priorities to different types of traffic, define flows

for Internet Protocol (IP) and Internetwork Packet Exchange (IPX) packet fields, assign

a precedence to the fields of the flows you define, and establish queuing policies.

• Configuration of security filters and access control lists (ACLs). An ACL is a list the

SSR keeps to control access to or from various services.

• Drag-and-drop VLAN setup and administration.

• Detailed reporting in the hypertext markup language (HTML) format.

System Requirements

CoreWatch can run in the Solaris, Windows NT, and Windows 95 environments. As

shown in the following table, CoreWatch’s system requirements depend upon your

operating system. The table identifies which browser to use with each operating system

and gives the minimum hardware requirements for each environment.

CoreWatch Capabilities

CoreWatch lets you perform the following operations:

• Access Configuration Expert, which is a Cabletron Systems utility that you use to

configure your SSR as discussed later in this guide.

• Perform the following monitoring tasks on the SSR as discussed later in this guide:

– Monitor the status of an SSR’s ports, modules, power supplies, and other hardware

components.
