How to view the Gen2 capture card properties
Viewing the Gen2 capture card properties allows you to verify what you think is happening at the card level (such as SFP activity, link speed, auto-negotiation) is actually happening. Additionally, configuration changes to the card can be made here.
Tip! These settings can be viewed remotely using Windows RDP or an equivalent remote desktop application. You might find this useful for checking SFP and link states when physical access to the GigaStor is not feasible.
Some benefits of viewing the Gen2 capture card properties include:
Verifying if an SFP...
is present and in which port.
is active or idle.
is operating at the speed you expect.
Verifying the board’s...
hardware acceleration (HA) status.
auto-negotiation settings per port.
ID string that also contains the firmware version.
PCIe lane speed1.
power range (good /bad)
operating temperature (good/bad)
Seeing configurable options for...
per port auto-negotiation.
GPS cable distance (GPS antenna sold separately)
Tip! Be sure to disable auto-negotiation for TAP connections, and enable auto-negotiation for SPAN connections.
To view the Gen2 capture card properties:
1. On the GigaStor system, choose Start > All Programs > Accessories > Windows Explorer.
2. Choose Computer and right-click and choose Manage.
The Computer Management window opens.
3. In the tree on the left, select Device Manager.
4. In the tree on the right, expand Network Instruments Capture Adapters.
5. Right-click the capture card entry and choose Properties.
 
The SFP State shows the type of SFP connected. C for copper and F for fiber.
Link state is a way to see if the Gen2 capture card is synchronized with the SPAN/TAP/Observer Matrix. If the link state is not green, there is a problem. Click Advanced Settings tab to try and change the adapter speed or auto-negotiation. Close the windows and go back to see if there is any change.

Packet capture does not start on Gen2 capture card
If Packet Capture does not start and there is no date and time information below the packet capture graph, you may need to reinstall the drivers for the Gen2 capture card.
Observer Analyzer must be running in application mode, not service mode. See Switching between the probe and analyzer user interfaces to switch to application mode.
You are using the Gen2 capture card. See Changing the monitored network adapter.
Several steps may be necessary to isolate the specific issue. Complete them in order.
Figure 15: Packet Capture not working
1. If Observer is open, close it.
2. Unplug all cables and remove all SFPs from the Gen2 capture card. Wait a few seconds and reinsert the SFPs and connect the cables.
3. Start Observer and start a packet capture.
Are you still experiencing the issue? If so, continue.
4. Ensure you are using the latest version of Observer.
See How to install or upgrade the software.
5. Restart Observer and start a packet capture.
Are you still experiencing the issue? If so, continue.
6. Close Observer.
7. Reinstall the driver for the Gen2 capture card.
See How to install the Gen2 capture card driver.
8. Start Observer and start a packet capture.
Are you still experiencing the issue? If so, continue.
9. Reinstall the firmware for the Gen2 capture card.
See How to reset the Windows registry to reinstall firmware.
10. Start Observer and start a packet capture.
Are you still experiencing the issue? If so, contact Technical Support as this likely indicates a more serious issue.
 
 
How to install the Gen2 capture card driver
Very rarely you may need to reinstall the driver for the Gen2 capture card. Doing so may resolve any issue you may have.
These instructions walk you through the process of updating the driver.
1. From Windows, choose Start. Right-click My Computer and choose Manage.
The Computer Management window opens with Device Manager selected.
2. Expand Viavi Capture Adapters.
You should see an adapter starting with the name Network Instruments or Viavi Solutions. The exact name will depend on when you purchased your system and what capabilities the adapter has. Make a note of the name of the capture card (for instance, oneGig2010 or tenGig2010).
3. Double-click the adapter and choose Driver.
4. Click Uninstall and confirm you want to remove the Gen2 capture card driver. Do not restart!
5. In Windows Explorer, open C:\WINDOWS\System32\Drivers and delete all Ni, Viavi, oneGig2010, tenGig2010, fortyGig2010, and hundredGig2010 driver files.
6. In C:\Windows\inf, search for any oem-named files. Search each of them (by double-clicking or opening in a text editor) for any references to Network Instruments. Delete any file that references Network Instruments.
7. Restart the system.
8. From Windows, choose Start. Right-click My Computer and choose Manage.
The Computer Management window opens with Device Manager selected.
9. Expand Viavi Capture Adapters.
This time you will see PCI Device instead of Network Instruments or Viavi Solutions.

10. Double-click PCI Device to reinstall the driver.
11. Click Next, then select Install from a list or specific location and click Next.
12. Select Don’t search. I will choose the driver to install. Click Next.
13. Click Have Disk.
Figure 17: Have Disk
14. Browse to C:\Program Files\Observer\DRIVERS\Gen2Gigabit.
15. Choose the directory that matches the Gen2 capture card you have installed from step 2 and select the .inf in the directory.
2010
2007 (out of service)
2005 (out of service)
Figure 18: .inf file
16. Click OK and Finish to install the driver.
17. Restart the system.
 
The Gen2 capture card driver is updated to the latest version.
 
How to reset the Windows registry to reinstall firmware
Updating the firmware may resolve some issues. For that to occur a flag in the Windows registry must be modified to trigger that portion of the installation program.
Back up your Windows registry file using whatever back method you choose.
Your Gen2 capture card must be one of these models: tenGig2007, oneGig2010, and tenGig2010.
Follow these steps to edit the Windows registry to allow the Observer installation process to reinstall the firmware.
1. From Windows, choose Start > Run. Type regedit.
The Windows registry opens.
2. Find HKEY_LOCAL_MACHINE > SOFTWARE > Network Instruments > Observer > General.
3. In the left pane, right-click and choose New > DWORD Value.
4. Type FFU.
5. Double-click FFU and change its Value data to 1.
6. Ensure you are using the latest version of Observer.
See How to install or upgrade the software.
7. Confirm the firmware should be updated.
Do not interrupt the firmware update process!
8. Restart the system.
 
The firmware is updated to the latest version.
