Port Indicator LEDs
Hardware blades in remote chassis come with LEDs that can flash to identify each port on the
blade. When you select specific ports in the
Select Ports for Domain Creation
dialog box, you
can match these ports to the physical hardware ports. Use the Port LEDs Blink button in the dialog
or select
Blink Chassis LEDs
from the
Hardware
menu to cause all the LEDs to flash for the port
pairs you have selected in the dialog.
Persistent Domains (Running Disconnected)
Once created and applied to the hardware, a domain on a sync group (remote chassis) will
continue to exist if you lose network connection, exit the TraceControl application, or connect to
another domain with no ports in common. There are two primary reasons for persistent domains:
• You can continue (reconnect) with any capture or other activity being performed for a domain
in the event that the network connection is lost between the client PC and Xgig Chassis.
• You can switch client systems and still be able to work with the same domain.
Although capture operations continue to run while disconnected from the TraceControl
application, the ports in the domain are no longer locked for exclusive use.
Another user can
lock the ports and use them for another purpose. If your remote analyzer(s) are in a network
environment with many users, it is recommended to run captures while connected, ensuring that
you get the capture you want. You can also use the password capabilities to set up an Xgig chassis
for your exclusive use to guarantee that captures continue to run when you disconnect from the
chassis.
When running disconnected in a network environment, it is strongly suggested that you name
domains clearly. This allows other users to see that domains have been created for ports, and may
prevent them from being allocated for other purposes. Also, if other users lock the ports and use
the same default domain name, you may not have the capture data you expect when you reconnect
to the Xgig chassis.
When you reconnect to an unlocked existing domain on an Xgig Sync Group, any modifications to
port configurations made prior to the reconnect will be discarded.
In the Port Status View, the software LEDs (B/W and F/P) only update while the ports are
connected in TraceControl. If you disconnect and then reconnect to a domain, the port LEDs will
be reset.
