1. OVERVIEW

Digital Networks WebView Description

This user guide describes Digital Networks WebView, a Web browserbased utility which allows you to remotely configure and manage Digital Networks products, including the DNswitch 800. There is no software to install as Web management capability is built into the switch’s management.

Digital Networks WebView provides a graphical, real-time representation of the front panel on the DNswitch 800. This graphic, along with additionally defined areas of the browser interface, allow you to interactively configure the switch, monitor its status, and view statistical information.

Digital Networks WebView provides a simple, intuitive method for managing the DNswitch 800. This switch can also be managed via the serial console, Telnet, or SNMP.

Features

• Switch configuration and monitoring from any Java-enabled browser

(Preferred browsers include Internet Explorer 4.0 or above, or

Netscape Navigator 4.0 or above)

• Easy to navigate menuing system

• Detailed parameter descriptions using the Help button

• Switch operating status viewing front panel color indications

• Alarm configuration capability

• Web management enable

System Requirements

The requirements for running Digital Networks WebView are relatively simple. You will need a Java-enabled, frames-capable Web browser and a TCP/IP network connection to the switch, whether over a local network, a remote private network, or over the Internet.

When connecting over the Internet, the integrity of your connection will have an impact on the speed and performance of tasks. If your connection is subject to prohibitive periods of network congestion, or experiences high packet loss, you may need to consider a different Internet service provider.

In addition, Digital Networks WebView uses SNMP for some of its communications with the switch. This may cause problems when the application is run across some Internet firewalls, which may be configured to disallow SNMP access.

DNswitch 800 Overview 1

Conventions

This guide uses the following user input conventions:

• When you read “Select,” use the mouse to either select the link identified by a hand icon, or select the identified button or area.

• When you read “Enter,” type in the text and select the button identified in the procedure.

2 Overview DNswitch 800

2. USING WEB-BASED MANAGEMENT

Setting Up Web Management

Before running Web-based management, some basic configuration of the switch may need to be performed. The following information at a minimum must be configured or known for the switch to be managed:

• IP Address

• Administrator password

• HTTP Server Enable

In addition, several other parameters may need to be configured or known to properly communicate with the switch or allow full management capability. These include:

• Default Gateway

• Trap Destination and Community Name

Configuration of these items may be made from the console user interface, which is accessible via either the serial console or Telnet. Refer to the DNswitch 800 User’s Guide that came with your system for more information about setting up either of these connections to the switch. The following subsections describe the required configuration.

Setting an IP Address

The IP address for the switch must be set before it can be managed with Digital Networks WebView. The switch IP address may be automatically set using the BootP protocol, in which case the actual address assigned to the switch must be known. Refer to the DNswitch 800 Management Guide.

The IP address may alternatively be set manually as follows:

1. Starting at the Main Menu of the console user interface, select

Management Setup Menu / Network Configuration / IP Configuration.

2. Select IP Address from the menu and enter the IP address.

3. Select Subnet Mask from the menu and enter the appropriate mask.

4. Press <APPLY>.

DNswitch 800 Using Web-Based Management 3

Setting a Default Gateway

The default gateway parameter defines the IP address of a router or other network device to which IP packets are to be sent if destined for a subnet outside of that in which the switch is operating. This parameter must be set if you are attempting to manage the switch using Digital Networks WebView from a remote network or across the Internet.

1. Starting at the Main Menu of the console user interface, select Management Setup Menu / Network Configuration / IP Configuration.

2. Select Gateway IP from the menu and enter the router IP address. Press <APPLY>.

Setting the Administrator Password

Management access to the switch using Digital Networks WebView is restricted based on the an administrator password. Administrators have read/write access for parameters governing the switch. You should therefore assign a password to the default administrator (User Name: admin) as soon as possible, and store it in a safe place. (If for some reason your password is lost, or you cannot gain access to the system’s configuration program, contact Digital Networks Technical Support for assistance.)

1. Starting at the Main Menu of the console user interface, select Management Setup Menu / Console Login Configuration.

2. Move to the Password field for the User Name “admin” in this menu, and enter the password. Press <APPLY>.

Setting Trap Destinations

If you wish to record SNMP traps, or events, generated by the switch, you must configure the destination for IP Trap Managers. A trap destination is the IP address of the system being used to manage the device, in this case the IP address of the computer system on which Digital Networks WebView is being run.

1. Starting at the Main Menu of the console user interface, select Management Setup Menu / SNMP Configuration / IP Trap Managers.

2. Select an entry for an IP Trap Manager from the menu, then enter the IP address and community name.

3. Move to the Status field, and use the Space bar to select ENABLED.

4. Press <APPLY>.

4 Using Web-Based Management DNswitch 800

Enabling Web Management

The HTTP Configuration menu is used to enable or disable the ability to manage the switch with Web management. The HTTP Server parameter must be set to ENABLED before Digital Networks WebView can be used to manage the switch. If it is desired to disallow Web management of the switch, this parameter should be set to DISABLED

1. Starting at the Main Menu of the console user interface, select

Management Setup Menu / Network Configuration / HTTP Configuration.

2. Select HTTP Server, and use the Space bar to toggle between

ENABLED and DISABLED.

Starting and Stopping Digital Networks WebView

Do the following to use Digital Networks WebView:

1. Start a Java-enabled Web browser from any machine with network

access to the switch. (Preferred browsers include Internet Explorer

4.0 or above, or Netscape Navigator 4.0 or above.)

2. Enter the IP address for the switch you want to manage in the URL

field of the browser.

3. The screen shown below will appear, prompting you to enter the user

name and password for management access.

Use the name for the default administrator (admin), and the password previously entered in the Setting Up Web Management section. This will allow read/write access to the switch.

The full application will now launch. A four-frame page will display with the product graphic located in the upper right hand frame.

4. To stop Digital Networks WebView, close the Web browser

application.
