Chapter 1

Getting Started

This chapter briefly describes the software features and requirements for the EX2500 Web Device Manager, and explains how to access the Web Device Manager start page:

EX2500 Web Device Manager Features on page 1

EX2500 Web Device Manager Requirements on page 2

EX2500 Web Device Manager Features

Network administrators can access switch configuration and monitoring functions through the Web Device Manager. The Web Device Manager has the following features:

Many of the same configuration and monitoring functions as the command-line interface (CLI)

Intuitive and easy-to-use interface structure

Password protection

Nothing to install; the Web Device Manager is part of the EX2500 switch software

Automatic upgrades with each new software release

NOTE: You can perform most configuration and monitoring tasks through the Web Device Manager. For a comprehensive set of commands, use the command-line interface (CLI). See the EX2500 Ethernet Switch Command Reference.

EX2500 Web Device Manager Features 1


2

EX2500 Web Device Manager Requirements

EX2500 switch

Installed EX2500 switch software

PC or workstation with network access to the switch’s management interface, as configured using the management module

Frame-capable Web-browser software, such as the following:

Netscape Navigator 4.7x or later

Internet Explorer 6.0x or later

Mozilla FireFox 1.0.4 or later

JavaScript enabled in your Web browser

Switch Setup

Before you can access the Web Device Manager, minimal configuration is required on the EX2500 switch.

IP InterfacesAt least one IP interface must be configured on the switch. Each IP interface address provides a point of access for EX2500 switch management. The default management interface is 1, which allows access to EX2500 switch management.

For complete information about configuring IP interfaces, see your EX2500 Ethernet Switch Hardware Guide.

Enabling and Disabling EX2500 Web Device Manager AccessBy default, Web Device Manager access is enabled. If you need to disable or re-enable access, use the following command from the command-line interface:

ex2500(config)# [no] access http enable For more information about accessing and configuring the switch through the CLI, see your EX2500 Ethernet Switch Command Reference.

Web Browser Setup

Most modern Web browsers work with frames and JavaScript by default, and require no additional setup. However, you should check your Web browser’s features and configuration to make sure frames and JavaScript are enabled.

NOTE: JavaScript is not the same as Java. Please make sure that JavaScript is enabled in your Web browser.

EX2500 Web Device Manager Requirements

Chapter 1: Getting Started

Starting the EX2500 Web Device Manager

When the switch and browser setup is done, follow these steps to launch the Web Device Manager:

1. Start your Web browser.

2. Enter the switch IP interface address or domain name in the Web browser’s URL field.

For example, if your switch has an IP interface with a network IP address of 10.10.10.1, you could enter the following:

If the IP interface’s address has a name on your local domain name server, you could enter the name instead. For example, you could enter the following:

3. Log in to the switch.

If your switch and browser are properly configured, you are prompted to enter a password:

Enter the account name and password for the switch’s administrator or user account. The default account name is admin, and the default password is admin. For more password information, see your EX2500 Ethernet Switch Command Reference.


Chapter 1: Getting Started

4. Allow the Web Device Manager Dashboard page to load.

When you enter the proper account name and password combination, the Web Device Manager Dashboard page appears in your browser’s viewing area.

You might experience a slight delay while the Dashboard page is being initialized. Do not stop the browser while loading is in progress. When loading is complete, a folder icon appears in the left-hand navigation window.

NOTE: The sample screens that appear in this guide might differ slightly from the screens displayed by your system. Screen content varies based on the type of switch unit that you are using and the firmware versions and options that are installed.

Navigation Window

The navigation window is used for selecting a particular switch feature to act upon. Status, statistics, or configuration forms for the selected item will appear in the forms window, depending on the context chosen on the toolbar.

The navigation window contains a tree of folders, sub-folders, and feature icons:

You can click any closed folder to open it and reveal its contents. Click any open folder to close it. Click any feature icon to load the appropriate status, statistics, or configuration form in the forms window.

Some folders also have forms. If the name of the folder is underlined, click the name to display the appropriate form.

Forms Window

When a feature icon is selected on the navigation window, a status, statistics, or configuration form is displayed in the forms window. The exact nature of the form depends on the current context selected on the toolbar, as well as the type of information available. Not all feature icons have forms for all contexts.

Some forms display switch information such as settings, status, or statistics. Others allow you to make configuration changes to switch parameters.

Navigation Window

Chapter 2: EX2500 Web Device Manager Basics

Message Window

Switch log messages are generated by events such as login and logout activity, password changes, configuration changes, and switch reboots.
