The WebViewer has an intuitive interface that facilitates managing the MGX 8260 Media Gateway. Using the WebViewer, you manage the MGX 8260 from a workstation with a standard Web browser.
Using the WebViewer, you can perform the following tasks.
You access the WebViewer using a standard Java-enabled web browser, like Netscape or Microsoft Internet Explorer. Figure 13-1 shows the opening screen.
Every WebViewer screen has three panes:
1. System information
2. Navigation
3. Display and control
The WebViewer presents MGX 8260 status and configuration information in the following views:
The chassis view shows the 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 on 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:
These screens display a summary of installed cards, configured services, or other information. Figure 13-2 shows an example a screen that displays card configuration and status information.
These screens contain additional buttons that link to other configuration screens. For example, the "+" icon links to the form for adding a card.
You use configuration forms to define the parameters for a given card or service, as shown in the example form that contains card configuration information (see Figure 13-3).
These forms contain both informational and user-defined fields. In some cases, the fields use hyperlinks to additional configuration forms. Due to security restrictions, not all users can access configuration forms.
You use a standard Web browser, such as Netscape Communicator or Microsoft's Internet Explorer, to communicate with the WebViewer interface of the MGX 8260 Media Gateway. 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 a copy from Netscape or Microsoft and install it on your machine.
Microsoft Internet Explorer has to be version 4.0 and up. For the Java-based Chassis View to display correctly, ensure that sufficient memory and disk space is available for gif, jar, and html files to be correctly loaded and executed. Minimize the applications running on the PC or workstation.
To configure Microsoft Internet Explorer, follow these steps:
Step 2 Click Settings on the Temporary Internet files pane
Step 3 Click Every visit to the page.
Step 4 Click OK.
Netscape Communicator has to be version 4.5 and up. For the Java-based Chassis View to display correctly, ensure that sufficient memory and disk space is available for gif, jar, and html files to be correctly loaded and executed. Minimize the applications running on the PC or workstation.
To configure Netscape Communicator, follow these steps:
Step 2 Click Advanced and Cache in the Category pane.
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 2 Select Navigator in the Category pane.
Step 3 Click Clear History.
Step 4 Click Edit; then click Preferences.
Step 5 Select Advanced and Cache in the Category pane.
Step 6 Click Clear Memory Cache.
Step 7 Click Clear Disk Cache.
Step 8 Click OK.
Step 9 Close Netscape and then restart it.
The management station communicates with the MGX 8260 Media Gateway over the management IP network. To use this network, you must initialize the IP address and gateway of the MGX 8260 management interface.
Assuming you installed the MGX 8260 Media Gateway using the installation procedure in this book, the management interface is already configured. If your IP network includes a firewall, you must also open an http port to the MGX 8260 Media Gateway.
At the logon prompt, enter a valid account and password for the MGX 8260 Media Gateway. Use the default account for new installations until you configure custom user profiles.
When the browser is first connected to the 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 to a Cisco MGX 8260 chassis 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 on the Chassis View button on the navigation pane to refresh the display.
If the web connection is terminated due to processor switchover, reset, or other reason, close the browser, restart the browser, and establish the connection by repeating the logon process.
