Chapter 2: Hardware Settings

Configuring your GigaStor

Your GigaStor probe can be configured in many different ways and tuned for your environment.

Defining your subnets in GigaStor

You can specify subnet properties for the GigaStor to allow for statistical aggregation of devices within the
Statistics tabs in GigaStor Control Panel.
1. Choose Capture > GigaStor Control Panel.
2. Click the Settings button.
3. Click the Subnet tab.
4. Use the Add, Delete, Modify, and Delete All buttons to configure the subnet settings for the GigaStor. When
you define subnets in the GigaStor Control Panel, the Observer analyzer adds that subnet information to its
index files. All future data analyzed will have subnet filtering readily available as well as statistical data. On
the IP Stations tab you see your subnets and you can perform statistical analysis based on subnets.
When you analyze data from captures with index files without any subnets defined, there will be no subnet
available in the IP stations tab even if the analyzed data includes some index files with the new subnet
information.

Tracking individual analysis ports

When using the Gen2 capture card in your GigaStor, you can track statistical information per physical port. Data
captured by the Gen2 capture card is indexed to show on which port the data arrived. You can further choose
to use physical ports to filter statistics. This means that information on the Statistics tab at the bottom of the
GigaStor Control Panel is dependent on which physical ports are selected.
Note:
If you are using virtual adapters on your Gen2 capture card in your GigaStor probe, you should not attempt
to analyze the packets on a per-port basis.
1. Choose Capture > GigaStor Control Panel.
2. Click the Settings button.
