Installing the Interface Cards and Drivers Safety and Handling Precautions Danger! Electrical current from power, phone and communications cables can be hazardous. To avoid potential shock hazards: • Only use grounded sockets for connecting equipment to the power supply. • Do not carry out any installation, maintenance or (re)configuration work and do not connect or disconnect any power cables during an electrical storm.
Installing the Interface Cards Install the Network Instruments Probe Software as described in the RMON1/2 & Advanced Probe User Guide. You must install this software before you install the hardware so that Windows will have access to the custom drivers.
Windows XP will attempt to recognize and install drivers to match the new hardware. Make sure that you have installed the Network Instruments Probe software; you must supply a directory that the Network Instruments install program creates to the Found New Hardware wizard.

The WAN Interface card isn’t recognized at all, so you need to have already installed the Network Instruments Probe software when you turn the system on. When the Found New Hardware wizard asks you for the driver location, specify the C:\Observer Files\Drivers\WAN directory, which contains the custom driver for the WAN Interface card.

Choose “Search for a suitable driver for my device.” Click Next. The wizard asks where it should look for the driver files: Choose “Specify a Location” and click Next. The wizard displays a file locator: Enter or browse to the following directory (assuming C:\Observer Files is your Observer directory): C:\Observer Files\DriversWAN Installing the Interface Cards and Drivers...

Click Next. The wizard informs you that the driver it found lacks a Microsoft digital signature: Click Yes. Network Instruments has tested and verified that the driver works correctly with Observer and Probe on Windows 2000. After installing the driver, the wizard displays a confirmation dialog telling you that the driver was successfully installed.
Page 21
Although Windows 2000 reports that it found the correct driver for the Network Instruments 10/100 NIC, the standard driver that it has installed needs to be updated to work best with Network Instruments Probe or Observer. A custom driver is required to make the 10/100 NIC work optimally with Probe and Observer.

• Efficiency History • Replay Packet Capture Analyzing a WAN Link with Observer In general, the WAN analysis works much like Ethernet analysis. One difference is that, when appropriate, Observer identifies WAN links by their Data Link Connection Identifier (DLCI) rather than by MAC address as is done with standard protocol analysis. In addition, many WAN statistical modes break out the data by DCE, DTE, and summary to reflect the full-duplex nature of WAN links.
Page 37
To set the CIR for a DLCI or group of DLCIs, click the edit DLCI CIR button on the Discover Network Names mode window. The following dialog is displayed: Add a DLCI (or select one from the list and click Modify). Type or use the spinbox to set the CIR in Kbits/sec for the DLCI.
pie, graph and dial views. The display setup dialog (click Settings to access), lets you choose what ports to display as well as color and scale options. WAN Vital Signs by DLCI In WAN Observer, the Network Vital Signs display is replaced by the WAN Vital Signs by DLCI mode.
Column Description DTE FECN under The number of packets seen on the DTE side of the link that had the Forward Explicit Congestion Notification bit set, even though the bandwidth usage was within the Committed Information Rate (CIR). Normally this number should be zero. If bandwidth usage exceeds CIR, congestion is expected.
The WAN Load by DLCI mode in dial view shows transfer rate, CRC error rate, FECN/BECN frame rates graphed on dial meters. DLCI CIR Setup Click Settings and then the DLCI CIR Setup tab to display a dialog that lets you enter DLCIs and their corresponding Committed Information Rates.
Top Talkers Just as in standard Observer, Top Talkers shows the IP and MAC address of stations on your network sorted by volume of traffic generated and received. In WAN Observer, the MAC Address tab shows DLCIs sorted by volume of traffic. Also, the sorting and charting statistical criteria (such as percentage of packets, packets per second, etc.) that apply to WAN is a subset of those available for standard network analysis.
Choose the desired filter rule from the menu. A dialog is displayed letting you set the filter rule options. Refer to the Observer Reference Guide and online help for further information about using filters and editing rules. Triggers and Alarms WAN Observer adds WAN-related criteria to the standard Triggers and Alarms mode.
Page 43
Check the alarms you wish to set, then click the Triggers tab to set the criteria by which the alarms will be triggered: Note that most WAN alarms can be set on the DTE or DCE side or both; note also that the Committed Information Rate displayed is that which you set in Discover Network Names mode.
