8.10 Creating a Payload Match
You can configure PETracer to trigger, count, and restart on a specific payload pattern
within a Transaction Layer Packet (TLP). In Recording Rules, create a New event of the
desired TLP type. An icon appears that represents that event type in the Available Events
area. Right-click the icon and select Properties to bring up the Properties dialog box for
the event.
Select the Payload tab to bring up the pane that lets you configure payload pattern. You
can match up to four patterns, labeled 0 through 3.
For each pattern, you specify the following:
Offset dword: Indicates the DWORD you want to match within the payload (range is 0
through 1024). For example, if you want the Analyzer match a pattern in the first DWORD
of the payload, enter 0. If you want the Analyzer to match a pattern in the thirty-fifth
DWORD, enter 35.
Bitmask: Indicates which bits you want to match for the DWORD indicated. You can
enter any of the following in the bitmask area:
• X (bit not relevant)
• 1 (present)
• 0 (bit not present)
