By default, Observer recognizes a Gen3 capture card as a single network adapter. However, you can make multiple clones of the capture card, called virtual adapters, and use each independently.
Your hardware appliance must have one of the following:
Gen2 capture card
Gen3 capture card
Each virtual adapter is a cloned Gen3 capture card that can have physical ports assigned to it in any quantity and combination. In this way, Observer can then see and use multiple network adapters as if they physically existed in your hardware appliance.
By default, you already have one virtual adapter: it matches the installed Gen3 capture card exactly, unless you accidentally deleted this virtual adapter or unassigned some of its ports. It can be recreated by following these same steps.
To create a virtual adapter:
1. In Observer, right-click the Gen3 capture card-equipped probe instance from the probe list, and click Probe or Device Properties.
A Gen3 capture card-equipped probe instance shows (Gigabit) or similar after the name.
2. Click the Virtual Adapters tab.
Figure 24: Virtual Adapters tab
3. Click New Adapter.
The Assign Ports to Virtual Adapter window opens.
4. Type a name in the Adapter Name box.
5. Select physical ports from the Available Ports list, and click Add.
You can select more than one physical port by holding CTRL as you click.
6. If this virtual adapter should operate during certain days and times only, select Schedule virtual adapter ports and follow the prompts.
If you choose to set a schedule for your virtual adapter, the remaining steps in this procedure may not be followable as written.
7. If the virtual adapter should skip (discard) duplicate packets, select Skip duplicate packets.
8. Select each added port, click Edit Port, and type a useful description for each port such as its connected device.
This description appears in the GigaStor Control Panel in Observer.
Note: If you want to filter on physical ports, an option in the hardware acceleration settings is described at .
9. Click OK to save the virtual adapter and close the Virtual Adapters window.
Changes to virtual adapters are not be saved until OK is clicked in the Virtual Adapters window.
The virtual adapter appears in the list of available network adapters when creating a probe instance. This allows you to assign the virtual adapter to a specific probe instance, among other benefits.
You should create a new probe instance for any virtual adapter you create, and assign the virtual adapter to that probe instance. This is because, by default, new virtual adapters are not assigned to any probe instance, so no data is collected with that virtual adapter until the virtual adapter is assigned to a probe instance.
