• Scrambling
This setting applies only to the 8G and 4G Fibre Channel ports. It allows you to specify
whether the capture will include scrambled data.
• FEC (Forward Error Correction)
This setting applies only to 16G Fibre Channel ports with the Link Speed set to 14.0250 Gbps
and 10GigE ports on the 2 port 10G Multi-function Xgig blade. It allows you to specify
whether FEC is enabled in the link or not. It also has an
Auto
option that detects FEC
automatically.
• Capture and Trigger Setup Tab
From the Capture and Trigger Setup tab, set what traffic to capture and what traffic to ignore
and select how you want the analyzer to trigger.

Clock Sync
The clock on the all Xgig chassis is synchronized with your local system by using the Clock Sync
operation from the Xgig Web Utility. See the
Xgig Family Hardware Guide, the Xgig5000 Family
Hardware Guide , or the Xgig1000 Hardware Guide for more information on the Xgig Web Utility.
Synchronizing the clock ensures that timestamps in any captured data will match your system
clock. Synchronization is only required the first time you use the chassis or, if another user has
reset the chassis clock.
Note that if you perform a Clock Sync operation after you have started a capture operation, the
capture will not use the updated timestamps from the Clock Sync operation. Subsequent captures
will use the new timestamps.
Applying the Configuration to Hardware
A TraceControl configuration controls starting and stopping analyzers, specifies capture filters,
and other conditions such as frame size. All configuration information specified in the
TraceControl Configuration window is applied to the hardware.
Press the Apply Configuration button to load the configuration to the hardware. If you start a
capture before you apply the configuration, this step is automatically taken before the capture
starts. You can also select
Apply Changes to Hardware from the Hardware menu to load the
configuration to the hardware.
