Chapter 1, Introduction The Xgig Systems
The Xgig Systems
The Xgig Family of Distributed Systems for Monitoring, Analysis, and Testing are multi-purpose
systems designed for engineering, field service, and network operations personnel. Xgig platforms
can be rack-mounted at your data center or strategically located anywhere in your network. For
Fibre Channel, Gigabit Ethernet, PCIe/NVMe, or SAS/SATA applications, Xgig chassis contain a
set of hardware analyzer blades that attach through SFP or XFP transceivers to the circuit or
device under test and software programs for hardware control and data analysis. For detailed
information about each of the Xgig systems, refer to the Xgig Family Hardware Guide, the
Xgig5000 Family Hardware Guide, or the Xgig1000 Hardware Guide on the product USB
memory drive.
The Xgig Analyzer software features data capture, real-time performance reporting, protocol
analysis, and error rate measurements. The software automatically extracts and decodes the data
correctly. The software displays the data in several formats for statistical analysis. Extensive find,
hide, and filter capabilities speed up the job of protocol analysis.
Xgig Blades
Blades within an Xgig chassis perform application-specific tasks. The Multi-Function Blade ports
can support a variety of different functions depending on the license for the blade. Possible
functions include analysis, traffic modification, and traffic generation.
Each blade consists of four major elements: serial gigabit connection, real-time performance
measurement, filter and trigger, and capture to memory. Xgig blades ensure both accurate data
collection and transparency on the link. The blade has sophisticated triggering and filtering to
isolate error conditions in the data. Pre-capture filtering can expand the capture time to minutes.
For detailed information about each type of Xgig blade, refer to the Xgig Blade Hardware Guide,
the Xgig5000 Blade Hardware Guide, or the Xgig1000 Hardware Guide on the product USB
memory drive.
Xgig Fixed-Port Systems
An Xgig fixed-port system is a self-contained bench setup Xgig system. These systems are
available as either fixed-function (Analyzer) or multi-function. All ports, connectors, and controls
found on an Xgig chassis containing Xgig blades are present on these systems. The multi-function
system ports can support a variety of different functions depending on the license for the system
ports. Possible functions include analysis, traffic modification, and traffic generation.

Connecting the Xgig Analyzer to a Target System Chapter 1, Introduction
Connecting the Xgig Analyzer to a Target System
There are three methods for placing an Xgig analyzer in a Fibre Channel or Gigabit Ethernet
system, as shown in Figure 1. These are:
• Point-to-point
• Hub Port Snoop
• Optical Splitter Snoop
Refer to Appendix B, “Connection and Wiring Examples”
connecting analyzer ports.
Figure 1: Placing the Analyzer in a Target Network System
for examples of the physical wiring for
Xgig Analyzer User’s Guide 5
Chapter 1, Introduction Connecting the Xgig Analyzer to a Target System
With the point-to-point connection, the Xgig is placed in a series, between the source and
destination. If the analyzer is configured for analog passthrough, a small amount of jitter, with an
acceptable eye opening, is added to the signal as it passes through the analyzer. If the Xgig is
configured for digital retiming at the front end, any jitter in the incoming signal is corrected, but
idle characters may be added or dropped from the traffic.
The transmit port of a hub is active at all times. A hub port is in bypass mode until a signal is
returned to the receive connection. This property of a hub can be used to passively snoop a
network.
Connect only the transmit port of the hub to the receive port of the analyzer. The analyzer captures
the data while the hub port remains in bypass mode. With the analyzer connected to one port on
the hub, you can remove or reconnect the analyzer without disturbing the links under test.
Another alternative is the Optical Splitter Snoop or Fiber Tap. This alternative allows you to
connect or remove the analyzer without disturbing the links under test. This is valid only for Fibre
Channel or Gigabit Ethernet.
If you cannot interrupt the network and you need maximum versatility for sniffing at different
configuration points, consider using the Viavi Snoop GBIC or a Viavi Fiber Tap. This product
provides an additional pair of ports for simultaneous transparent monitoring of either Gigabit
Ethernet or Fibre Channel links without causing any link loading or down time of the system under
test.
Xgig Hardware to Xgig Analyzer Software Connection
For Xgig, the analyzer blade(s) resides in a different system from your Xgig client software. You
must have an Ethernet connection between the Xgig chassis and the system running your Xgig
client software. For Xgig1K and Xgig5K chassis, you may control the chassis using the USB
connection if it is supported by your Xgig client software.
Xgig Access Through a Firewall
In general, Xgig client software should be able to access an Xgig Chassis that lies behind a
firewall. Ports must be open as described in the following table to permit operation across a
firewall for Xgig applications:

Connecting the Xgig Analyzer to a Target System Chapter 1, Introduction
The main TCP port number used to communicate with an Xgig chassis is port 2000. If your IT
department blocks the TCP port 2000 on the network, you can still change it to 52000 or any other
number of your choice. However this change must be done on all client computers and all Xgig
chassis on your network at the same time, otherwise some chassis won't be visible and accessible
from some clients.
On the client side, you can change the default TCP port 2000 by selecting
from the
Apply to change the port. You can also change the TCP port for the most recently used chassis by
Start menu. A dialog appears where you can type in a value for the TCP port. Click
Edit Xgig TCP Port
clicking the chassis name(s) in the Most Recently Used Chassis section of the dialog. Again, you
must update all the clients and chassis on your network at the same time; otherwise the Xgig
applications will not see some chassis.
For sites where Xgig Maestro is not used, it is suggested that the DCOM port remain closed.
Network Address Translation (NAT) is not supported. An Xgig Chassis protected by a firewall that
uses Network Address Translation (NAT) cannot be accessed from Xgig clients outside the
firewall.
Finally, client-initiated chassis upgrades do not work across network firewalls since they use
random TCP port numbers between the client and the chassis. The Xgig client installers
automatically open the Windows Firewall for the syncgroupupgradeutil.exe and
probeupgradeutility.exe, but again, network firewalls will prevent the client-initiated chassis
upgrades from succeeding. In that case, you should always upgrade your chassis from the chassis
Administration web page.

analyzing the data. The first three programs are described in this book. Refer to the Xgig Expert
help system for information on Xgig Expert.
Xgig TraceControl
Xgig TraceControl configures and runs the protocol analyzer to capture data. Using the Xgig
TraceControl, you can set the payload filter and trace size, select the capture and trigger criteria,
and start/stop the capture of data.
Xgig Performance Monitor
Xgig Performance Monitor displays real time performance and error parameters passing through
the analyzer. Use the Xgig Performance Monitor to monitor the performance of each channel and
detect errors. You can vary the update rate to suit your measurement and all meters scale
automatically. Both the instantaneous, average, and maximum rates are plotted on the screen.
Xgig T raceView
Xgig TraceView displays the data captured by the analyzer. Xgig TraceView will either show data
currently in trace memory or open a file containing saved data. Xgig TraceView displays traces,
searches and filters the traces, and extracts portions of the trace. You can export the traces to a
delimited format that can be used by other databases and spreadsheets.
Xgig Expert
Expert is an analysis tool for Fibre Channel, FCP-SCSI, Gigabit Ethernet, FCoE, IP, TCP, iFCP,
FCIP, SAS, SATA, PCIe/NVMe, AHCI, and iSCSI traffic. Xgig Expert automatically identifies
protocol violations and errors within the trace as well as providing a rich set of metrics for
performance and behavioral analysis. Traces from Gigabit Ethernet topology, Fibre Channel
topology (Arbitrated Loop, Public Loop, Switch Fabric, etc.), and SAS/SATA topologies are
supported and automatically analyzed when opened.

Xgig Software Limitations
Domains that contain ports on different chassis when Xgig chassis are cascaded are called
inter-chassis domains. Intra-chassis domains refer to domains where all ports are on the same
chassis. A Sync Group can have up to 8 locked inter-chassis domains. There is no limit on the
number of unlocked domains, except that each port must belong to only one domain at a time.
Also, the number of intra-chassis domains is only limited by the number of port-pairs on the
chassis.
If you perform a soft reboot of the Xgig chassis, all ports will be disconnected.
Xgig Expert performance is related to several factors – the size of the trace, the number of ports in
the trace, and the CPU speed and memory capacity of the computer running the Xgig Expert
client. You can improve performance by manipulating any of these variables. Reducing the size of
the trace information or reducing the port count in the trace will improve Xgig Expert's
performance. Increasing the processing power and memory of your client PC will also improve
performance. Although Xgig Expert will eventually process extremely large traces (e.g., 32 GB)
with extremely large port counts (e.g., 64 ports), opening such traces will take many hours.
If you need to open large-file/high-port-count traces, it is recommended that you add as much
memory and CPU speed to the client system as possible. It is also recommended that you make
sure you do not include more ports than are needed or make traces larger than needed when using
Xgig Expert.
