Cisco WebViewer Orientation

Cisco WebViewer Orientation

The Cisco WebViewer has an intuitive interface that facilitates managing the Cisco MGX 8260 from a workstation with a standard Web browser.

Cisco WebViewer Features

Using the Cisco WebViewer, you can perform the following tasks:

The Cisco WebViewer provides dedicated Cisco MGX 8260 information, including system settings, node configurations, service provisioning, and system test features. The Cisco WebViewer accesses information from the SNMP core, but presents it in extended text and graphic forms that simplify working with it.

The Cisco WebViewer provides real-time information on Cisco MGX 8260 status, alarms, events, and statistics. Using Java scripts and applets, the Cisco WebViewer constantly monitors the Cisco MGX 8260 and updates the user interface.

Every screen has a prominent alarm indicator that shows the current operational status. With a single click, users can obtain detailed information on outstanding alarms and events.

Also, the Cisco MGX 8260 can notify users by email when alarms or events occur.

The Cisco WebViewer reports current and historical performance data, and displays performance statistics when performance drops below user-defined levels. Using this feature, operators can react proactively to problems that degrade performance before the system fails.

The MGX 8260 Media Gateway enforces security with user accounts and access levels. Users must log onto the MGX 8260 Media Gateway before performing any task, and authenticated users can perform only those tasks permitted by their access level. The MGX 8260 Media Gateway supports up to 20 user accounts, each with access privileges ranging from full control to guest.

Using the alarm and test features, maintenance personnel can often diagnose and solve equipment problems directly from the Cisco WebViewer. For example, if a DS1 line raises a performance alarm, maintenance personnel can diagnose the problem with loopback and BERT tests and initiate corrective action.

Cisco WebViewer Interface

You access the Cisco WebViewer using a standard Java-enabled Web browser, like Netscape or Microsoft Internet Explorer. Figure 1-1 shows the opening screen.


Figure 1-1: Cisco WebViewer Main Screen


Every Cisco WebViewer screen has three panes:

    1. System information

The Cisco WebViewer displays real-time system information at the top of the display in the System Information pane. System information includes the node name, date and time, current user, device type, and alarm status. The system updates this pane every two minutes.

You can view a summary of alarms by clicking the alarm indicator, or can configure system settings by clicking anywhere in the middle of the pane. These are shortcuts to screens that you can also reach from the Navigation pane.

    2. Navigation

The Navigation Pane contains a set of sliding menus that open a display in the adjacent Display and Control pane. When you click a menu item, an additional submenu may slide out. From this pane you can access most of the Cisco WebViewer configuration screens.

    3. Display and control

The Display and Control pane shows details about the menu item selected in the Navigation pane. The opening screen shows a graphic image of the Chassis View, but other views display operation status or configuration forms. Some screens contain additional buttons or hyperlinks that facilitate configuration tasks.

Cisco WebViewer Screens

The Cisco WebViewer presents Cisco MGX 8260 status and configuration information in the following views:

Chassis View

The Chassis View shows the Cisco MGX 8260 front panel, including an accurate representation of the installed cards and their current LED states. The cards and LEDs are active areas on the screen, so you can get more information about an LED indication by clicking it. To view configuration information about a card, click elsewhere on the desired card.

In the Chassis View, the following LEDs are displayed and updated in real time:

Status Screens

Status screens display a summary of installed cards, configured services, or other information. Figure 1-2 shows an example of a screen that displays card configuration and status information.


Figure 1-2: Card Configuration and Status Screen


Many status screens contain buttons that open other configuration screens. For example, the plus icon links to the form for adding a card.

Configuration Forms

You use configuration forms to define the parameters for a given card or service. Figure 1-3 shows an example of a form that contains card configuration information.

The configuration forms contain both informational and user-defined fields. In some cases, the fields contain hyperlinks to additional configuration forms. Because of security restrictions, not all users can access configuration forms.

Setting Up the Cisco WebViewer

You use a standard Web browser, such as Netscape Communicator or Microsoft's Internet Explorer, to communicate with the Cisco WebViewer interface of the Cisco MGX 8260. Microsoft Internet Explorer is preferred over Netscape Communicator because web page reloading is generally faster. If you don't already have a browser installed, download one from Netscape or Microsoft and install it on your machine.

Configuring Microsoft Internet Explorer

Microsoft Internet Explorer has to be Version 4.0 or greater. For the Java-based Chassis View to display correctly, ensure that sufficient memory and disk space are available for gif, jar, and html files to be correctly loaded and executed.

To configure Microsoft Internet Explorer, follow these steps:

Step 1   From the Tools menu, select Internet Options.

Step 2   On the Temporary Internet Files pane, click Settings.

Step 3   Click Every visit to the page.

Step 4   Click OK.

Configuring Netscape Communicator

Netscape Communicator has to be Version 4.5 or greater. For the Java-based Chassis View to be displayed correctly, ensure that sufficient memory and disk space is available for gif, jar, and html files to be correctly loaded and executed.

To configure Netscape Communicator, follow these steps:

Step 1   From the Edit menu, select Preferences.

Step 2   In the Category pane, click Advanced and Cache.

Step 3   Set the memory cache to 1024 K bytes.

Step 4   Set the disk cache to 50000 K bytes.

Step 5   Under "Document in cache is compared to document on network," select Every time. This option assures that the page you see is always the latest.

Step 6   Click OK.

To troubleshoot Netscape Communicator when the Chassis View does not display, follow these steps:

Step 1   From the Edit menu, select Preferences.

Step 2   In the Category pane, select Navigator.

Step 3   Click Clear History.

Step 4   Select Edit; then click Preferences

Step 5   In the Category pane, select Advanced and Cache.

Step 6   Click Clear Memory Cache.

Step 7   Click Clear Disk Cache.

Step 8   Click OK.

Step 9   Close Netscape and then restart it.

Configuring a Management Path

The management station communicates with the Cisco MGX 8260 over the management IP network. To use this network, you must initialize the IP address and gateway of the Cisco MGX 8260 management interface.

Assuming that you installed the Cisco MGX 8260 using the procedures in the Cisco MGX 8260 Hardware Installation Guide, the management interface is already configured. If your IP network includes a firewall, you must also open an http port to the Cisco MGX 8260.

Usage Guidelines

At the logon prompt, enter a valid account name and password for the Cisco MGX 8260. Use the default account (SuperUser) and password (cisco) for new installations until you configure custom user profiles.

When the browser is first connected to the Cisco WebViewer, users are prompted to grant the execution privilege for specific Java applets. Users should grant the access and select always allow this access for subsequent operations.

Users can have up to ten browser sessions with a Cisco MGX 8260 from either the same or different workstations (IP addresses). However, only one browser session on an IP address can correctly receive the real-time chassis view updates. For those browsers that do not receive real-time updates, users must click Chassis View on the navigation pane to refresh the display.

If the web connection is terminated because of processor switchover, reset, or other reason, close the browser, restart the browser, and establish the connection by repeating the logon process.
