Licensing 

Ixia Licensing

Any chassis which runs IxServer must have an IxOS license installed on it. 

IxOS 8.20 EA ships with Ixia Licensing 4.50 EA.

IxLicensing 4.50 EA upgrades IxLicensing 4.40 EA Patch1 and earlier versions. If this is upgraded on release 3.xx, 
Ixia Licensing Utility (ILU) and License Server Plus (LS+) will replace Ixia Registration Utility (IRU)
and License Server (LS). 

Some of the key benefits of this new licensing system are:

    - Simplified activation procedure
    - Improves offline activation using Request files.  
    - Enhanced Host ID calculation to increase uniqueness of Host ID.
    - Allows remote activation of licenses
    - Allows configuration of Proxy settings


For more information about the new IxLicensing system, please refer to the
"Ixia Licensing Management User Guide" provided with the Ixia software, or downloadable
from the Ixia web site.



Installing a License

Ixia Licensing 4.50 EA upgrades Ixia Licensing 4.40 EA Patch1 and prior versions on the 
machines. If the setup is upgraded from versions prior to 4.30 to 4.50,
the setup cannot be reverted to the previous version and will need to stay at 4.50 EA after the upgrade.

This upgrade can be performed in below 2 ways:

  - Ixia Registration Utility (IRU) to Ixia Licensing Utility (ILU)
  - Previous version of Ixia Licensing Utility (ILU) to the latest version of Ixia Licensing Utility (ILU)

In case of IRU to ILU upgrade, ILU will override IRU and its registration numbers will be migrated as
activation codes in ILU.

During installation the system checks the connectivity with Ixia Licensing web servers. 
Based on the connectivity, you can perform the upgrade in the following ways:

  - Online Migration
  - Offline Migration



Prerequisite Installation Notes

Ixia Licensing 4.50 EA installs .Net 4.0 on Chassis and .Net 4.5.1 on Clients  and VM Chassis.
 
NOTE: Ixia Licensing 4.50 EA installs .Net 4.5.1 on client machines. If an older
      release of an Ixia product containing .Net 4.0 hotfix is installed on top
      of this release, .Net 4.0 hotfix installation may fail. The workaround is
      to uninstall .Net 4.5.1 and then reinstall the older release of Ixia
      product and then modify this release of Ixia Licensing.

Installation Notes 

Installation on XGS2-HS and XGS12-HS chassis

Starting from IxOS 8.13 EA, the XGS2-HS, XGS12-HS chassis can optionally be converted
to run Native IxOS, for improved stability and performance.
The conversion removes the Microsoft Windows OS, and replaces it with IxOS running natively on the chassis (over Linux OS).
Once complete the chassis are effectively converted to XGS2-HSL and XGS12-HSL. 
For more information, including the conversion process procedure, please download and
read the Converting_XGS_and_PSOne_to_Native_IxOS.pdf document available on the IxOS Downloads And Update
(https://support.ixiacom.com/support-overview/product-support/downloads-updates/versions/21)


Installation on PerfectStorm ONE appliance

In order to run IxLoad 8.20 EA, the PerfectStorm ONE appliance must be converted to run Native IxOS. 
The new Native IxOS provides for improved stability and performance. The conversion removes the Microsoft Windows OS, 
and replaces it with IxOS running natively on the appliance (over Linux OS). For more information, including the conversion process procedure, 
please download and read the Converting_XGS_and_PSOne_to_Native_IxOS.pdf document available on the IxOS Downloads And Update
(https://support.ixiacom.com/support-overview/product-support/downloads-updates/versions/21)


Windows Chassis Installation Requirements

When installing IxOS 8.20 EA on a chassis, a minimum of 512MB of installed 
RAM and a minimum 2GB of free disk space on Drive C: is required. 
    
 
In addition, be sure that at least 400MB of temporary space is available.
If your chassis does not meet these requirements, please contact Customer Support
at  support@ixiacom.com or 1-877-FOR-IXIA about appropriate upgrades.
 
On heavily loaded chassis configurations, 1GB of RAM is recommended.
 
 
NOTE: Non-English versions of the Windows operating system are not supported.
 
NOTE: When installing from CD, some virus scanning configurations present 
      a malicious code alert during execution of the Windows autorun feature. If
      this occurs, right-click the CD-ROM drive icon in Explorer and 'Explore' 
      the CD. At the root of the CD, double-click on the index.htm file.

NOTE: "Untrusted publisher" dialog box appears when installing on Windows 7.  
      Microsoft has issued a hotfix to resolve this issue. It is included in the IxOS installer 
      and requires a reboot early in the installation process, if not already installed.
      Please refer to the following Microsoft knowledgebase item for more information: 
      2921916


Installation Features

The IxOS installation program offers the user a selection of five installation 
options: Client, Server, Demo Server, Tcl Server, and Hardware Manager. The 
Server option is normally chosen for installation on Ixia chassis. The Demo 
Server option should NOT be chosen for chassis installations: it is used for 
client installations.

 

Server Configuration Options

There are three options offered for configuring IxOS server operations: Service,
Startup, and Manual (None). 

1. The Service option creates a Windows service for IxServer which can be 
   managed via the Windows Service Control Manager. Desktop shortcuts are not 
   created when using this option. However, Start Menu shortcuts are still 
   available. The usual IxServer user interface is not available. As a result, 
   configuration of IxServer (or Tcl Server) requires the user to stop the 
   services and invoke the server via the Start Menu shortcuts. Once the 
   configuration is complete,  the servers can be closed via the user interface, 
   and the service restarted.

   NOTE: Presently, Telnet connectivity is unavailable when Tcl Server is 
         configured to run as a service.
      
2. The Startup option starts IxServer when any user logs on to the chassis. 
   Start Menu shortcuts are also created.

3. The Manual(None) option simply creates Desktop and Start Menu shortcuts. 
   IxServer and/or Tcl Server are not automatically started when the user logs
   in to the machine or the machine is rebooted. 

   NOTE: Regardless of the service option selection, Demo Server is always configured
         to operate manually.

      

Tcl Version Option

IxOS is now shipping with Active State Tcl 8.5. When Client is selected for 
installation, the user is offered to install Tcl 8.5. If you select Tcl 8.5, 
be sure that your Tcl-based applications will run under this version. 
 
NOTE: When using IxOS 8.20 EA, the Tix 8.5 Tcl extension is delivered
with the Tcl 8.5 installation.

NOTE: If the Solaris TCL console doesn't start because it's missing libiconv or libgcc,
follow these steps:
1. extract the archives on the Solaris machine
2. run the commands:
    pkgadd -d libgcc-3.3-sol10-sparc-local
    pkgadd -d libiconv-1.14-sol10-sparc-local
    pkgadd -d libintl-3.4.0-sol10-sparc-local

UNIX Installation Notes

In order to run the GUI installer, your client machine must be configured with
an operational X-windows server.

Be sure to set your DISPLAY environment variable to the host name or IP address 
of the client machine on which you want the installer GUI to display. Below are 
examples for setting the DISPLAY environment variable using various shells. If 
you need environment configuration assistance beyond this, please consult your 
System Administrator.

 // enable connections to X Server
 xhost + or xhost [remote hostname]
 
 // set DISPLAY environment variable
  // determine shell
  echo $SHELL

  // depending on what shell you use - Bourne shell (bsh or sh), 
  // Bash (bash- Bourne shell again), C shell (csh) or Korn shell (ksh); 
  // set DISPLAY environment variable:

   // bash:
   export DISPLAY=hostname:0
   
   // bsh or ksh:
   DISPLAY=hostname:0
   export DISPLAY
 
   // csh:
   setenv DISPLAY hostname:0 
   
   
If you are updating an existing installation, be sure to run the installer as the
same user who initially installed the software.

Always run the uninstaller prior to removing any files manually.

If installing as the root user, using an install location is a network-mounted 
file system, ensure the root user has write permission to the file system.

To install the Tcl Client on Linux, perform the following steps: (Note:
the binary file name 'IxOS8.20.XXX.XXXLinux.bin' is used in the example 
below. In most cases, the file name will be different.)

3.1 Copy the 'IxOS8.20.XXX.XXXLinux.bin'  file to the system.

3.2 Before starting the installation, make sure the IxOS binary is executable. 
    If not, type "chmod +x  'filename'" (where 'filename' is the binary file name). 
    Check the permissions of the target directory to make sure full permission 
    is granted.

3.3 Execute the IxOS installer file (use the gui option if installing via console 
    or remote shell).
    Example: ./IxOS8.20.XXX.XXXLinux.bin 

3.4 When the installer prompts, select Tcl version 8.5.
 
3.5 Follow the installation prompts to complete the installation.

If the installation fails, check that there is enough disk space on the system 
by using the "df -ak" command. 

There must enough space in the /tmp folder (to extract the files), and in the 
target folder (where files are to be installed). If the /tmp dir does not have 
enough space, specify the dir by setting IATEMPDIR environment with path to the 
folder where you have enough free space.
The following example show the use of the options:

export IATEMPDIR=/tempdir
./IxOS8.20.XXX.XXXLinux.bin

To install IxOS using tgz package, perform the following steps:

3.1 Create the destination folder.
3.2 Extract and copy all folders and files from the tgz package into the destination folder. 

3.3 After installation, set the following variables:(Note: Examples below match
    the sample installation; they must be altered to match user installation.)

        IXIA_HOME=/export/home/ixos8.20
        IXIA_VERSION=8.20.XXX.XXX
        TCLLIBPATH=/export/home/ixos8.20/lib

3.4 Optionally, specify the following environment variables to specify the 
    location of the log, sample, and results files for IxOS:

	IXIA_LOGS_DIR=$IXIA_HOME/logs
	IXIA_RESULTS_DIR=$IXIA_HOME/results
	IXIA_SAMPLES=$IXIA_HOME/samples
	IXIA_TCL_DIR=$IXIA_HOME/lib

3.5 If the Tcl option was installed with an IxOS installation, add Ixia's bin 
    and lib directory to the PATH and LD_LIBRARY_PATH variable in order to use it. 
    For example:

        IxiaLibPath=$IXIA_HOME/lib
        IxiaBinPath=$IXIA_HOME/bin
        PATH=$IxiaBinPath:$PATH
        LD_LIBRARY_PATH=$IxiaLibPath:$LD_LIBRARY_PATH
 
        

Downgrading to a previous version of IxOS

When downgrading to a release of IxOS prior to 5.10 SP2 on a chassis, all Ixia
applications must be un-installed from the chassis and re-installed after the 
IxOS downgrade is completed. Please perform the following steps using the 
Add/Remove Programs application.

    1. Un-install current IxOS installation.
    2. Un-install all Ixia applications.
    3. Un-install StatEngine and all PCPU packages
    4. Install IxOS 
    5. Install previously un-installed application. Note, these application 
       installations install StatEngine if required. There is no need to 
       install this separately.
 
Note, any card, port, stream, etc., files generated by IxOS are forward 
compatible but not backward compatible.

Tcl/Tk Support for Client Applications 

Tcl Server was first supplied free of charge starting with IxOS 3.80 EA. 
Installation of this feature is optional; it should only be installed if 
required for specific application.
 
Installation and operation of the Tcl Server is required for IxChariot when 
running hardware performance pairs, for IxANVL when running VNIC (Virtual 
Network Interface Card) and for IxAuthenticate. The Tcl Server can be installed 
on either the Ixia chassis or a separate Windows workstation. 

The following limitations exist with respect to Wish and Tcl shell support:

   Tcl shell does not run on any version of Windows with Ixia software. Under
   Linux or Solaris, the Tcl shell runs on any version of Tcl greater than or 
   equal to 8.3.

Field Notices 

Laser Warnings

The 10G load modules may use a Class III laser. Precautions should be 
taken to prevent personal injury. The spring-loaded safety cover should always be 
securely in place over the port when there is no cable installed. Avoid exposure
and never look directly into an open port aperture.
 


Installing / Uninstalling Load Modules

Modules in the XGS12-SD, XGS12-HS, XGS12-HSL, XGS2-SD, XGS2-HS, XGS2-HSL, XG12, XM12, and XM2 can be installed/uninstalled 
with the chassis operational.  

For all chassis types, use caution when inserting or removing multi-slot modules 
to evenly insert and remove. Load modules are tightly spaced; avoid contacting 
the adjoining modules while inserting and removing.


Safety Notice Regarding Ixia Load Modules

WARNING: In order to prevent accidental injury to personnel, do not leave transceiver 
(SFP/SFP+/QSFP/QSFP28/CXP/CFP4) cages uncovered on Ixia load modules. When transceivers 
are not installed, port end caps (Part No. 503-006) must be used. The metal edge of 
the transceiver cage is SHARP. To avoid injury, ALWAYS keep the transceiver cage covered.
   
Contact Ixia Technical Support to obtain end caps. Please reference Ixia Product
safety notice Part No. 913-0715 Rev A, June 2009. For additional information
refer to Chapter three of the IXOS Getting Started Guide under the section, 
Notes, Cautions and Warnings.


Use Ejector Tabs Properly

Ejector tabs on load modules are to be used only to eject a load module from
the chassis backplane connector. They are not designed to support the weight
of the load module. Ejector tabs can bend or break if used improperly as handles
to push, pull, or carry a load module.

Miscellaneous

Bug Number Notes
1404716 Sometimes when on the same chassis large number of ports are used by other application (like IxNetwork) control of the ports owned by BPS may be lost.

NOVUS100GE8Q28+FAN

Bug Number Notes
1389289 On some occasions after restarting IxServer port links will come up but IxExplorer will display port links as down. Pressing refresh (F5) in IxExplorer corrects the displayed state.
1406987 Each PCPU port is rate-limited to 2.5Gbps for fair sharing.
1411818 Currently there is no message to block the user from performing operations when the card is performing mode switch(for example from 100 to 25G)

Novus10/1GE16DP

Bug Number Notes
1411035 Captured packets not correct when Trigger Position = 0%, 100%
1415793 Novus 10G support auto-detect between 1G and 10G, which no other Ixia product offers. As a result, we can't differentiate between port mode as 1G or 10G, as this my change dynamically. So, we will leave this as type 1 (kFramingEthernet) which is generic, and does not state specifically 10G or 1G (or 100M).
1417209 This Load Module does not support rxEqualizerControlValue parameter in TapSettings.
1423697 Bit Offset feature is not supported on Novus10/1GE Load modules.
1424834 Port link may remain up if an SFP port is configured for 100 Mbit but does not have the correct SGMII 100Base-FX transceiver and is connected to another 1G port.
1425285 When internal loopback is configured at 100M in SFP+ mode, L1 link will not come up. Workaround: Change configuration to 1G/10G SFP+ or 100M/1G/10G RJ45 to use Internal Loopback.
1425966 Rx Active Status LED blinks green rather than red when receiving errors.
1427159 If PFC has traffic running with max frame size of more than 5000 bytes Q0 on all queues and is paused, it is possible to encounter a condition where FCS and Sequence errors occur.
1427547 When running with no cable connected, or during mode change the Novus port may report a hardware fault in the IxServer log with an error message of "PacketLengthErr", "RxFaultFilterFramingError" or "RxPktFifoEmptyFault". These messages indicate that the port received invalid data. They do not indicate a physical hardware failure. After the errors are reported, the port can be used as normal once the link has been re-established.
