Captured data dwords may also be used in the Substitute Data Dword test state action.

Test Initiator and Target
To begin the scenario creation process, you press the New Scenario button in a library
window or on the SAS InFusion application toolbar. As the first step in creating a
scenario, the application prompts you for scenario name, a short description (optional),
and the direction of traffic to which any traffic changes apply. Changes are, for example,
injection or removal of data or a primitive.
You identify direction of traffic change, or modification, in terms of traffic origin. The
application uses the following conventions:
•
From Initiator: Change is made to traffic coming from test host (for example,
CRC error is injected into traffic stream sent from initiator to target).
•
From Target: Modification is made to traffic coming from the target (for
example, CRC error is injected into traffic stream sent from target to initiator).
Figure 41 shows the first prompt in the scenario creation process. When you click on it,
the Scenario Properties dialog box appears, allowing you to enter the scenario name, a
short description, and direction of traffic change (Figure 42).
