Three-state triggering options allow you to specify different capture conditions for pre-armed and
armed states. Highlight the Pre-Armed or Armed state bubble, and drag a template from the
Available Templates Browser
tree into the
Capture these
/
But not these
panes of the Capture
Filter Editor.
Three-State Trigger Example - Arm and Trigger
In this example, before the arm the analyzer captures Any Traffic . After the Hello command is
seen, the analyzer will begin to capture
SCSI over Fibre Channel Protocol (FCP)
traffic. The
default setting for the Pre-Armed and Armed states is to capture Any Traffic .
The port-pair continues to capture data until the trigger condition is met. When the trigger event of
Any Error (found by HW) is seen in the data stream, all ports in the domain continue to capture
until 50% of the buffer is filled with post-trigger data and then all ports stop.
The percentage of the buffer containing data immediately after the Trigger event is controlled by
the Post Trigger Fill setting on the
Capture and Trigger Setup
tab. If the Post Trigger Fill
position is set to 50%, then 50% of the buffer will contain data seen after the Trigger event.
Press the
Apply
button to load the configuration to the selected analyzer port.
