Getting Started with IxNetwork : Introduction to IxNetwork

Introduction to IxNetwork

IxNetworkª of Ixia is specifically targeted for the performance and functionality testing of high-speed, high-capacity routersand switches. IxNetwork operates only on port-CPU-based test modules of Ixia. With these modules, each test portsupports an independent PowerPC running Windows and protocol state machines.

IxNetwork provides a powerful, yet easy-to-use, graphical user interface (GUI) that you can use to configure and runcomplex tests. With IxNetwork you can quickly and easily configure protocol variables and parameters to suit a particulardevice under test (DUT). Combined with Ixia family of Chassis and port-CPU-based Load Modules, you can useIxNetwork to create a test environment tailored to your specific requirements.

IxNetwork offers the flexibility to customize the application to meet a wide range of requirements for testing complexnetwork topologies, consisting of thousands of routing or switching devices. You can emulate millions of routes andreachable hosts within the topology. You can also, easily scale the size of the emulated topologies by adding additionaltest ports.

IxNetwork also provides with the ability to customize millions of traffic flows to stress the data plane performance. Youcan create sophisticated configurations using powerful wizards and grid controls in the graphical user interface. With itsenhanced real-time analysis and statistics, IxNetwork is capable of reporting comprehensive protocol status and detailedper-flow traffic performance metrics.

Benefits of IxNetworkIxNetwork 6.30 SP1 is designed to replace, and improve upon, IxNetwork 6.30. IxNetwork 6.30 SP1 adds enhancedprotocol capability and testing features.

The following sections describe the features of IxNetwork:

• GUI Framework

• Enhanced Port Management

• Traffic Wizard

• Test Composer

• Enhanced Statistics Reporting

• Log View Window

• Application Traffic

• Quick Tests

• Flow Tracking

• Capture Settings

• Analyzer

• Data Miner

Getting Started with IxNetwork : GUI Framework

GUI FrameworkIxNetwork provides a GUI framework, with a main IxNetwork window that displays sub-windows for Port Configuration,Protocol Configuration, Creation of QuickTests and Traffic Configuration (for L2-L3 Traffic or Application Traffic).Additional panels display Statistics and Captures. You can toggle the Configuration and Statistics information display onand off. With this design, you can simultaneously view protocol configurations, statistics for traffic and protocols, andstatistics information. An example of the GUI framework is shown in the following figure.

Figure 4-1. IxNetwork GUI Framework Example

Enhanced Port ManagementIxNetwork Port Management feature allows you to assign physical ports for immediate configuration. As an alternative,you can create a port configuration ÒimageÓ for a port type, such as Ethernet, without tying up an actual physical port.You can configure protocols for this Òtest portÓ and save the resulting configuration for later use on a physical port. Anexample of the Port Management window Port Selection dialog box is shown in the folloiwng figure.

Getting Started with IxNetwork : Enhanced Protocol Configuration

Figure 4-2. IxNetwork Port Selection Example

Enhanced Protocol ConfigurationIxNetwork supports emulation of Internet-scale routing topologies to determine the scalability limits, and is designed toemulate a wide variety of bridging and routing protocols. Easy-to-use Protocol Wizards allow you to quickly and preciselyset up complex topologies, in a step-by-step process for initial setup of small to large-scale test topologies across multipleIxia ports. The wizards simplify the setup of complex network scenarios across multiple protocols simultaneously. Inaddition, IxNetwork spreadsheet GUI paradigm provides the entry, editing, and viewing of large configurations acrossmultiple test ports. Once you create a network topology, you can copy it easily across any supported Ixia test port. Anexample of an IxNetwork configuration wizard is shown in Figure 1-3.

BFD, L2TP, and PPPoX protocol support are present in IxNetwork. Authentication support for DHCP, Static IP, andMAC addresses are also present. Protocol wizard is enhanced with the addition of BGP VPLS (Kompella Draft) to the L2VPN wizard. Support for use of RSVP-TE and ISIS together in wizards is added.

You can integrate previously configured protocol interfaces into Interface Groups and use in setting up trafficconfigurations, with filtering based on IP version, presence of VLANs, or the type of ATM encapsulation (in case of ATMports). Support to protocol interfaces for Stacked VLANs (QinQ) is also present.

Traffic Groups option is present, which you can automatically configure and display in the Traffic Group window whileconfiguring L2 and L3 VPNs, and Multicast VPNs (MVPNs) using the protocol wizards. You can also manually configureTraffic Groups in the Traffic Group window. The use of Traffic Groups simplifies the setup of traffic for complextopologies such as L2 and L3 VPNs, and MVPNs.

Getting Started with IxNetwork : Traffic Wizard

Figure 4-3. IxNetwork Protocol Configuration Wizard Example

Traffic WizardThe Basic Traffic Wizard and Advanced Traffic Wizard allow you to create millions of traffic flows for validatingemulated networks and hosts. The wizards provide great flexibility to set up wire-rate traffic streams to validate everyreachable network and host.

With the help of the Basic Traffic Wizard you can configure traffic with endpoints that have the same encapsulation type.You can configure bi-directional traffic movement easily and quickly with the help of the newly introduced checkbox.Multi-field tracking also can be enabled easily with the Basic Traffic Wizard. An example of the IxNetwork Basic TrafficWizard is shown in Figure 1-4.

- 10 of 80-

Getting Started with IxNetwork : Traffic Wizard

Figure 4-4. IxNetwork Basic Traffic Wizard Example

The Advanced Traffic Wizard allows to configure flexible traffic set-ups. It has the ability to support mixed encapsulationtypes and allows bi-directional traffic movement. The Advanced Wizard allows to edit and increment field values foroptimized QoS testing with the help of the Packet Editor.

Flow Groups feature provides the ability to create traffic groups based on selected criteria such as rate, frame size, andtransmit properties. Unique traffic profiles can be created with the help of this function.

An example of the IxNetwork Advanced Traffic Wizard is shown in the following figure.

Figure 4-5. IxNetwork Advanced Traffic Wizard Example

- 11 of 80-

Getting Started with IxNetwork : Test Composer

The final step of the traffic wizard is to set up the receive ports to track the traffic flows with detailed QoS measurementsof packet loss, throughput, and latency. You can track the traffic flow based on MAC addresses, IP addresses, TOS/DSCP,MPLS labels, or custom fields. The traffic wizard also provides optional capability for custom-editing the actual packetheaders in the new version of the Packet Editor window, such as inserting additional layers of protocol headers. Much ofthe packet customization capability provided by IxExplorer of Ixia is included in the traffic wizard. An example of theAdvanced Traffic Wizard -Packet QoS Editor is shown in Figure 1-6.

Figure 4-6. IxNetwork Traffic Wizard Packet QoS Example

Test ComposerTest Composer is an Ixia software component, integrated into IxNetwork that permits the creation of complex multi-steptest scripts integrating events, DUT configuration commands, local or external procedure calls, and flow controlinstructions that permit branching the script flow based on a step result evaluation.

Test scripts created using the Test Composer plug-in support multiple simultaneous connections to test devices that canbe configured using a variety of protocol interfaces: Telnet, TL1, SSH1/SSH2/SSHAuto, CmdTool, TclSh, Raw, SNMP,Syslog, and COM.

In addition to these protocol interfaces, Test Composer scripts also support a default session of the IxNetwork type. Forthis default IxNetwork session that is automatically created for every Test Composer script, a number of pre-configuredevents are available for configuring Ixia chassis ports, applying test configuration files, starting protocol traffic, launchingtests, and retrieving test run results.

The TestComposer Online Help provides detailed information on the Test Composer window features. Press F1 to accessthe online help in the Test Composer window.

Getting Started with IxNetwork : Enhanced Statistics Reporting

Enhanced Statistics ReportingStatistics reporting for protocols has been greatly expanded, to provide far more detailed information about the protocolsetup process. Available statistics views include port statistics, global protocol statistics, traffic statistics, quicktests, andindividual statistic views for each of the protocols that you configure. You can tile up to four statistic windows forsimultaneous viewing. An example of the IxNetwork Statistics window, is shown in Figure 1-7.

Figure 4-7. IxNetwork Statistics Window Example

Log View WindowA global LogView window provides real-time information about the status of Port Management, Interfaces, Traffic, TestComposer, and Statistics. You can save the information in this window for later evaluation. In addition, the Port Tracewindow found in IxNetwork is still available at the port level for every protocol listed in the Protocol Window. An exampleof the IxNetwork LogView window, showing the progress of Port Manager, is shown in Figure 1-8.

Figure 4-8. IxNetwork LogView Window Example

Application TrafficThe IxNetwork Traffic Wizard allows the user to create traffic flows for Layer 4 through Layer 7 Application traffic, fortransmission over protocol routes, by providing a subset of the IxLoad capabilities within IxNetwork. This subset of theIxLoad features is called IxLoadLite. Refer to the IxLoad User Guide for additional information on the use of theIxLoadLite features.

When used for Application Traffic, the traffic wizard provides a step-by-step procedure to set up traffic between IPv4Application endpoints, running over routes that have been set up via one of the routing protocols, such as BGP. Users canselect which source and destination items will send and receive traffic, how they will be mapped to each item (one-to-oneor fully-meshed), and how the flows will be generated between advertised routes (one-to-one or fully-meshed). The traffic

- 13 of 80-

Getting Started with IxNetwork : Quick Tests

wizard will then automatically create fully-meshed or one-to-one application flows between all participating endpoints.After the traffic endpoint type and source/destination pair has been set up, an Application Traffic Profile can be selected toemulate the Layer 4-7 scenario. An example of the traffic window for Application Traffic is shown in Figure 1-9.

Figure 4-9. Application Traffic Window

Quick TestsThe Quick Tests feature allows you to use pre-defined tests.You can add, access, run, and customize these tests accordingto your requirements. Step-by-step wizards allow you to set up the Quick Tests. You can view the results of current tests,and previously run tests, and compared them in the Results window. An example of the Quick Tests window is shown inthe following figure.

Figure 4-10. Integrated Test Window

- 14 of 80-

Getting Started with IxNetwork : Flow Tracking

Flow TrackingThe Flow Tracking feature in the Traffic wizard allows an Ixia interface to track flows based on one or more fields. Thisfeature enables a Traffic window to be opened from Statistics; this view shows L2-L3 statistics for a single flow. The flowtracking settings apply to all traffic items transmitted to a particular port. Ingress tracking by source/destination endpointpair, egress tracking by VLAN, and latency tracking is shown in the following figure.

General Licensing StepsThe following steps indicate the general sequence to use when installing and licensing IxNetwork. These steps assumethat you will be installing the license server on your Ixia chassis. If you will be using a dedicated/standalone PC as alicensing server, see the Ixia License Management User Guide for detailed instructions. The Ixia license installation utilityis included in the IxNetwork CD build or download file.

CAUTION: To avoid licensing problems, be careful as you proceed throughthe licensing utility program. Do not just automatically click Next toproceed through the program, or licensing will not be successful and youwill not be able to use IxNetwork. You must read each installer screen andprovide the requested information. Although the installer steps you throughthe license installation process, the overview information here is provided toensure that you do not overlook important installation details. For moredetailed information on each step, refer to the License Management UserGuide.

IMPORTANT: The IxNetwork installer must be run on both the Ixia chassisand the client PC. When the installer is run on the chassis, it installs thelicense server component and the statistics engine. However, it does notinstall the client GUI software. When the installer is run on the client PC,the client software is installed.

There is a separate IxNetwork chassis installer available that is significantlyfaster than the full installer. Both version can be used to install IxNetworkon the chassis.

Chassis InstallationTo install an IxNetwork license onto an Ixia chassis:

1. Download IxNetwork to Ixia chassis from the Ixia Web site or the IxNetwork CD.

2. Launch the installer and answer the questions as required.

Python Client InstallationTo install Python Client, perform the following steps:

1. If Python 2.6 is not installed on the machine, download and install a stable release of Python 2.6 fromhttp://www.python.org/getit/releases/2.6/

2. Currently there is no installer, so you need to manually install the IxNetwork.py file. Normally the file will be installedin the standard location for third-party Python modules. This location varies depending on the platform and the way youbuild or install Python itself. On Unix (and Mac OS X, which is also Unix-based), it also depends on whether the moduledistribution being installed is pure Python or contains extensions (non-pure).

Platform Standard Installation Location Default valueUnix (pure) prefix/lib/pythonX.Y/site-packages /usr/local/lib/pythonX.Y/site-packages/IxNetworkUnix (non-pure) exec-prefix/lib/pythonX.Y/site-packages /usr/local/lib/pythonX.Y/site-packages/IxNetworkWindows prefix\Lib\site-packages C:\PythonXY\Lib\site-packages\IxNetwork

3. Execute IxNetwork.py.

IxNetwork and Test Conductor – Installation

To install the combined IxNetwork and Test Conductor installer there is a separate installation.exewhich is different from the general IxNetwork installation exe.

The combined installer provides the option to install Test Conductor only on Client side (TCinstallation option is unavailable on Chassis side) since Test Conductor interacts only with theIxNetwork GUI.

Test Conductor installation choice is only provided with the ÒInstall IxNetworkÓ and ÒInstallIxNetwork and IxNetwork-FTÓ options as described in the IxNetwork installation process (IxNetworkInstallation ).

- 27 of 80-

http://www.python.org/getit/releases/2.6/

Getting Started with IxNetwork : Configuring IxNetwork for Silent Installation

During the installation process, the only difference between the normal IxNetwork installation and thecombined installation is that an additional Install Test Conductor window is displayed.

Click Next to go to the next dialog box in the IxNetwork Installation process.NOTE:• The IxNetwork installation will not manage the Test Conductor installation

post-installation. All modification and repair operations are performed viathe Add/Remove Programs entry for Test Conductor.

• The combined installer will not support silent installation or installationthrough IxAdmin.

• The size of this new combined installer is higher than the IxNetwork Fullinstaller by about 380 MB.

• The combined installer will not support installation alongside the IxNetworkFull, IxNetwork Chassis installer or IxNetwork-FT (from the same build) onthe same machine.

NOTE: Just before the installation is complete, a separate installation is launched for TestConductor and runs independent of IxNetwork.IxNetwork doesnot checkwhether another version of Test Conductor is already installed onthemachine. Once invoked the Test Conductor installation would install or upgrade just like itdoeswhen installed independently. Successor failure of the Test Conductor installationwould not impact the IxNetwork installation.

NOTE: While uninstalling IxNetwork, Test Conductor is not uninstalled automatically. TestConductor has to be separately uninstalled through Control Panel/Add Remove Programs.

Configuring IxNetwork for Silent Installation

IxNetwork Silent Install is a feature which enables you to install IxNetwork software unattended. Asilent installation of IxNetwork is ideal for test scenarios or as part of a large-scale enterprisedeployment.

You can use the IxAdmin package to perform remote silent installations on multiple machinessimultaneously.

If you want to use Silent Installation to install IxNetwork software on an Ixia chassis, you must changethe policy that controls Silent Installation. See Preparing an Ixia Chassis for Silent Installation .

IxNetwork product silent install setup is discussed inIxNetwork Silent Install using .exe Package .

Preparing an Ixia Chassis for Silent Installation

Setting up the silent install for IxNetwork for a chassis involves activating specific features included inthe product package, and specifying the server operation mode via a command line dialog box.

The available features and properties (operation modes) are delivered as part of the installer. TableFeatures lists the features available, and Table Properties lists the properties.

To run the IxNetwork installer silently, use the IxNetwork<version><release>.exe package, where<version> is the version of the software, and <release> is the release number for the particularpackage. The .exe is extracted to %ProgramFiles%\IxiaInstallerCache\IxNetwork\<full_version>folderby providing a -e switch, for example, IxNetwork<version><release>.exe -e. The setup.exe file islocated in this directory.

Perform the following steps to set up silent installation using the .exe package.

1. Open a command line window.

2. Enter the following command line argument, in one line:

setup.exe [-s|-q] [-n] [i|x|r] [F.Feature1=Yes|No [F.Feature2=Yes|No]][P.Prop1=Val1 [P.Prop2=Val2]]

3. See IxNetwork setup.exe Package Examples below for examples of using the command line toset up silent installation.

Getting Started with IxNetwork : AES Scriptgen Setup

AES Scriptgen Setup

The AES ScriptGen feature of IxNetwork 6.10 requires a TCL platform with Threads and TbcLoadsupport. The TCL installed with IxOS does not support thread. To make use of this feature, there aretwo options:

• Use the tclsh8.4 from <IxOS_InstallDir>/lib/tcl_threaded/bin directory

• Use the new ixnetwish file located under <IxOS_InstallDir>/bin directory

Sample command lines are as follows:

1. package req ix_tc

2. package req tbcload

3. package req Thread

In GUI and Console mode, the IxNetwork installer creates two environment variables on the system viz. LD_LIBRARY_PATH and TCLLIBPATH to support this new feature. The value of LD_LIBRARY_PATH is set to append whereas thevalue of TCLLIBPATH is set to overwrite the existing setting.

If LD_LIBRARY_PATH is already set on the system and is pointing to non threaded TCL libraries then the threadedtclsh8.4 binary would throw errors when executed. To overcome this problem, set LD_LIBRARY_PATH explicitly to thepath of the lib folder (<IxOS_InstallDir>/lib/tcl_threaded/lib) of threaded TCL.

Refer to IxNComposerScriptGenReference guide for more information.

NOTE: AESScriptgen ismeant for the Linuxusers.

As shown in Applying the Source and Destination Pairs , traffic is sent from the source (on the leftpane) to the destination (on the right pane).

The Source/Destination Mesh type is, ÒOne-One.Ó Since two Ixia ports are being used, andbidirectional traffic is sent between the two ports, two sources and two destinations are created.(Each port acts as both source and destination.)

The Route Mesh type is, ÒFully MeshedÓ. Since there are 10 route ranges set up for each port, afull mesh will create 100 pairs of route ranges. The Encapsulation type is non-MPLS, and theEndpoint type is IPv4.

Creating the pairs at the high-level of the trees saves configuration time. Each port acts as bothsource and destination, so the Source / Destination Pair includes 2 source items and 2 destinationitems.Ó If you select individual items from the expanded tree, you must add two Source /Destination Pairs—one for each of the two directions of traffic.

Creating a Sample Test Composer Script

This section describes a sample operations sequence for defining a Composer test and saving it into the Test Conductordatabase.

Test Overview

For the purpose of our example, we are considering a Composer test that established an IxExplorer session with an Ixiachassis and executes commands on two chassis ports, the first transmitting a packet stream and the second receiving it.

The test connects to the Ixia chassis using an IxExplorer StartSession command, configures the test output using anexisting Tcl test configuration script, clears the statistics on the ports and starts the packets transmission. Aftertransmitting continuously for a period of 5 seconds, transmission on the first port is stopped and the values of theframesSent (on port 6.1) and the framesReceived test statistics (on port 6.2) are retrieved into a composite variable usinga Stat Get command.

After retrieving the fsent and frecv statistics values from the composite variable using GetValue Tcl commands, the twovalues are compared using an If / Else statement, and depending on the evaluation result, the test return a non-zero valuefor a pass status or a zero value for a fail status.

Getting Started with IxNetwork : Creating the Composer Test

Figure 6-39. Sample Test Overview

Creating the Composer Test

To create the test described in {Default ¦ Font}{Emphasis}{Hyperlink}A Simple IxNetwork Test{Default ¦ Font} proceedas follows:

1. While in the TestComposer module, click the New Composer Test button and type in a testname and an optional description in the Information window that appears.

2. Click the link and start adding the steps sequence described below.

Add an IxExplorer StartSession step that opens a connection to an Ixia chassis (piglet for purpose ofour example) and takes ownership of chassis ports 6.1 and 6.2. A username and a path to the IxOSinstallation folder on the chassis must also be configured.

StartSession ixe IxExplorer, Session Start chassis=piglet ports="(6.1 6.2)"

ownershipmode=force loginname=cliff ixospath=//piglet/Ixia/IxOS/ 5.20.401.100-EB

3. Add an Execute step that runs a ScriptGen Apply command on the session opened at step 1. Thiscommand applies an existing IxExplorer test configuration file to port 6.1 that will be transmittingpackets.

Execute ixe ScriptGen Apply ports=(6.1) filename=C:/ cfg6_1_tx30.tcl

4. Add an Execute Stat Clear step that resets the statistic counters on the two chassis ports.

Execute ixe Stat Clear ports="(6.1 6.2)"

5. Add an Execute Utility CheckLinkState step verifying the link status of the two ports.

Execute ixe Utility CheckLinkState ports="(6.1) (6.2)"

6. Add a Transmit Start step that initiates the transmission of a packets stream from chassis port 6.1.

Execute ixe Transmit Start ports=(6.1)

7. Add a Sleep step with a duration of 5 seconds, which keeps the port transmitting packets for thisduration.

Sleep 00:00:05.000

8. Add an Execute Transmit Stop which stops the packets transmission on port 6.1:

- 59 of 80-

Getting Started with IxNetwork : Set Up CSV Logging

Execute ixe Transmit Stop ports=(6.1)

9. Add an Execute Stat Get step that retrieves into the composite frameStats variable the values of theframesSent and framesReceived statistic for port 6.1 and 6.2 respectively.

Execute ixe frameStats Stat Get ports="(6.1) (6.2)" stats="-framesReceived -

framesSent"

10.Add an Assign step that uses the GetValue Tcl command to retrieve the value of the framesSentstatistic for port 1.6.1 into the fsent variable.

Assign fsent [GetValue frameStats framesSent Port 1.6.1]

11.Add an Assign step that uses the GetValue Tcl to retrieve the value of the framesReceived statisticfor port 1.6.2 into the frecv variable.

Assign frecv [GetValue frameStats framesReceived Port 1.6.2]

12.Add a Trace statement that prints out the fsent and frecv values by referencing the simple variablesdefined at steps 10 and 11.

Trace "frames sent: %d ::: frames received: %d" $fsent $frecv

13.Add a TclEval step that computes the tx_fps and rx_fps frames per second rates: TclEval set tx_fps [expr {$fsent / 5.0}]; set rx_fps [expr {$frecv / 5.0}]

14.Add a Trace statement that prints out the tx_fps and rx_fps values computed at the previous step.

Trace "tx rate (fps): %f ::: rx rate (fps): %f " $tx_fps $rx_fps

15.Add a StopSession step that terminates the ixe session to the Ixia chassis. StopSession ixe

16.Add an If step for testing the equality of the fsent and frecv values, and an Else statement within theIf step:

If ${fsent} == ${frecv}

<instruction 1>

Else

<instruction 2>

EndIf

17.Add a Return step with a 1 Passed argument that is executed when the If step evaluates true, andanother one after the Else statement with a0 Fail argument, to be executed when the If step evaluates false:

If ${fsent} == ${frecv}

Return 1 Passed

Else

Return 0 Failed

EndIf

Click Save. The Composer test is saved into the Test Conductor database using the name specified at step 1 and is addedto the applicationÕs Tests table.

IxNetwork License ManagementA growing number of Ixia software products use a new technique of licensing. Licensing is managed using the IxiaRegistration Utility (IRU). The IRU is automatically installed and run with the installation of licensed Ixia products.

IxiaÕs license management technique is the means by which Ixia:

• Ensures that its software is licensed and used appropriately.

• Allows Ixia customers to centralize and monitor their software usage.

Licenses are purchased from Ixia and issued to the customer via email. These licenses must be installed on-site in orderfor the licensed software to operate correctly. License installation for an Ixia software product can occur either:

• At the time of the software installation.

• Sometime after the software installation, but before software usage.

IMPORTANT: Licensed software cannot be used until the licensing process is complete.

- 65 of 80-

Getting Started with IxNetwork : Date-based versus Version-based Licensing

The licensing operation is accomplished with a simple wizard process and can be run from:

• The same computer on which the software was installed, or

• Some other Windows-based PC.

The computer used to perform the licensing process must be connected to the Ixia chassis and workstations in the labenvironment. If at all possible, it should also be connected to the Internet. If simultaneous connections to the lab networkand Internet are not feasible, it is still possible to complete all licensing operations; the process for off-line installation iscovered in the License Management User Guide.

Depending on the Ixia product, there are two types of licenses that can be purchased:

• A node-locked license (the only type used by IxNetwork) — this type of license is locked to aparticular chassis or workstation, and allows only certain software functions to run on that chassis orworkstation.

• A floating license — this type of license is stored on a License Server, and allows a set number ofchassis or workstations to use various software features. All chassis or workstations that will use thislicense must be connected to the License Server, and the server must be running for the licensed Ixiaproduct to function. Once the set number of users is reached for a particular license feature,additional users of the product are denied.

Both types of licenses are available from Ixia, and can be mixed to provide the best solution for the testing environmentÕsneeds.

Date-based versus Version-based LicensingIn the past, licenses were linked to the version of the software being licensed. For example, if a license for IxProduct 3.00was purchased, then the license was only good for the 3.00 version of IxProduct. If IxProduct was upgraded to version3.1, a new license was required. This is version-based licensing, and required the customer to frequently update theirlicenses.

From now on, all licenses issued are date-based licenses. Date-based licenses are valid for the entire period of theproductÕs service contract. For example, if a license is purchased for IxProduct 3.00, with a service contract of one year,IxProduct can be upgraded to a new version (or a service pack) any time during that year without requiring a new license.This requires less customer license management.

The new date-based licensing is backward-compatible with the old version-based licensing.

Temporary LicensesTemporary licenses are offered in the event that a purchased license is not available. This allows the customer to usepurchased applications even if there is a delay in obtaining a valid license.

Temporary licenses have a time limit (measured in days) and become invalid after the time limit expires. Warnings arepresented when the term of a license drops below 30 days.

A sample of a temporary license installation is shown in Temporary License Installation .

Evaluation LicensesEvaluation licenses are used to evaluate Ixia software products. They can be used for a limited number of days. They act inall respects as a regular license (they must be installed using the IRU), save for the fact that they have a time limit.

Tcl Notes for Use with LicensingAlthough the GUI offers the user the ability to create a temporary license, this cannot be offered while running a Tcl script.If a temporary license is required, the IRU should be run independently.

If your license resides on the chassis being used by your Tcl program, no adjustment is necessary. If you are using aLicense Server, please continue reading.

Although the GUI offers the user the ability to designate an independent license server as a menu option, no such optionis available to a Tcl program. Instead, an environment variable named IXN_LICENSE_SERVER must be set.

- 66 of 80-

Getting Started with IxNetwork : Prerequisites

If you are running your Tcl program on a Unix client, the environment variable must be set on the host running the TclServer. If you are running your Tcl program on a Windows client, it must be set on that client. Environment variables areset on a Unix host through the userÕs shell initialization script. Environment variables are set on a Windows host byusing the following steps:

1. Right-click on the My Computer icon on the desktop and then left-click on Properties.

2. Choose the Advanced tab from the System Properties dialog box.

3. Press the Environment Variables button at the bottom of the page.

4. In either the ÒUser variables for <user>Ó or ÒSystem variablesÓ list, if IXN_LICENSE_SERVERdoes not exist in the list, press New, otherwise Edit.

5. The name of the variable should be IXN_LICENSE_SERVER and the value should be the name orIP address of the license server machine.

PrerequisitesBefore installing a license, obtain the following:

• The Ixia generated registration email for the licenses being installed. The key contents of this emailare:

• A Registration Number (RN) — a unique number for the license.

• A Password — required to install the license.

• An understanding of which Ixia software products and chassis the license applies to.

• An understanding of whether a License Server is used in the Test Lab.

An example of this email is shown in the following figure (see IxNetwork License Management .). Be sure to note theRegistration number and Password, circled in the email example.

Getting Started with IxNetwork : Installation Scenarios

Installation ScenariosThere are four possible installation scenarios, described in the following sections:

• Licensing to a Chassis or Workstation via the Internet

• Licensing to a Chassis or Workstation Without the Internet

The Installation Host is the computer that is used to perform the licensing installation. This can be the same computeron which the Ixia software was installed, an Ixia chassis, a License Server, or a separate workstation.

Licensing to a Chassis or Workstation via the InternetIn this case, the Installation Host is connected to the Internet and licenses are installed to the workstation or Ixia chassisto which the license pertains (the workstation and the Installation Host can be the same machine). The Installation Hostmust also be connected to the workstation/chassis (if they are not the same machine).

Figure 7-3. Licensing to a Chassis or Workstation via the Internet

- 69 of 80-

Getting Started with IxNetwork : Licensing to a Chassis or Workstation Without the Internet

Licensing to a Chassis or Workstation Without the InternetIn this case, the Installation Host is not connected to the Internet and the licenses are installed to the workstation orIxia chassis to which the license pertains (the workstation and the Installation Host can be the same machine). TheInstallation Host must also be connected to the workstation/chassis (if they are not the same machine).

In order to complete the installation process, an additional computer is necessary —an Online Host. This machine mustbe connected to the Internet. It is necessary to transfer small amounts of information from the Online Host to theInstallation Host to complete the process. Email or a portable USB drive may be appropriate.

Figure 7-4. Licensing to a Chassis or Workstation Disconnected from the Internet

License Installation ExamplesThe following sections detail a simple online license installation for both a regular and temporary license:

• Regular License Installation

• Temporary License Installation

Regular License InstallationThe following example shows a typical online installation of a node-locked license on a local machine, with no licenseserver. Depending on the testing environment, other installations may have more steps.

Note: Depending on whether the license is being installed to a computer or a chassis, thewording in the IRU dialogs is slightly different.

1. If the IRU is not running, start it by selecting Start>Programs>Ixia>Licensing>IRU.

2. Click Register in the IRU, as shown in Licensing Start .

Troubleshooting

NOTE: Please refer to the LicenseManagement User Guide for anyadditional informationon troubleshooting licensemanagement issues.

Disk ID Reset UtilityIf the IxNetwork application is installed on a chassis with an invalid Volume Serial Number (VSN), then the setdiskidutility will launch automatically during the installation of the application. After the VSN has been changed, the user will beprompted to reboot the chassis. Upon rebooting, an autoupdate utility will then run and will check for any licenses thatexist, based on the old VSN. If licenses exist, the utility will automatically de-register/re-register the licenses and informthe user that the process is complete.

When the utility is run at the time of the IxNetwork license installation, a dialog box similar to the one shown in thefollowing figure is displayed.

Figure 7-1. Set Disk ID Warning

Select OK to continue with the change in the Disk ID number, or select Cancel to retain the old Disk ID. When finished,a dialog box similar to the one shown in the following figure is displayed.

Figure 7-2. Set Disk ID Complete

Select OK to complete the process.

The old disk ID number is stored in a file called restorediskid.bat. By running this batch file, the user can restore theold disk ID.

NOTE: Changing the Disk ID requires that you re-register all licensed applicationson thechassis. To assist in this process, a script is included with the Licensing that de-registers and
