Network Instruments WAN Probe Kit - Manual (Page 29)

Installing the Interface Cards and Drivers 23
10. Click Continue Anyway. Network Instruments has tested and verified that the driver
works correctly with Probe and Observer on Windows XP.
11. After the wizard finishes installing the driver, Click Finish to close the confirmation
dialog.
12. Repeat these same steps for updating the 10/100 NIC. When asked to specify a
location for the driver, enter (or browse to) this path (assuming C:\Observer Files is
your Observer directory):
c:\observer files\drivers\intel21143\win2000
13. Click through the rest of the wizard as you did for the 10/100 driver. After you click
Finish... on the last dialog, the custom driver installation is complete.
Configuring Ports Into Logical Links
You must define the physical ports on the WAN interface card or cards into logical links.
Each WAN interface card includes 1, 2 or 4 physical ports. By using the WAN Driver
Configuration tool to define logical links consisting of 1 or more ports, you will be able to:
• in the case of links with more than one port, obtain a cumulative view of statistics
from more than one port
• in all cases, create meaningful names that you will see in the Observer probe list.
A good situation in which to view multiple ports as a single link is in the case of a pair of
load-balancing WAN lines. Some link groupings make no sense and are not
recommended, such as configuring a link consisting of ports connected to WAN lines
coming from separate ISPs. Note that you can only create links from ports of the same
type; for example you cannot create a link that contains both HSSI and DS3 ports.
Starting the Configuration Utility
Before you start the configuration utility, make sure you have closed Observer and shut
down any Network Instruments Probe instances that may be running.
Click on Start->Observer->WAN Driver Configuration.
The configuration tool scans the system for NI WAN interface cards, displaying them in
the order they are physically installed in the bus. Each card is identified by bus and device
# (displayed at the top of the card), and the number of the physical slot the card occupies
in the PC bus.
The ports on each card are listed under the card ID label, along with any logical links the
port is associated with. If this is the first time the utility has been run, (or you have
