Current VSPERF documentation related to IXIA configuration (configuration guide at chapter 2.4.) is too brief.
Following topics are not discussed:

1. configuration values required for IXIA execution; List of IXIA specific configuration values to be explained follows

   # path to 'ixos' install path
   TRAFFICGEN_IXIA_ROOT_DIR = '/opt/ixos'
   
   # network address of IXIA chassis
   TRAFFICGEN_IXIA_HOST = ''
   
   TRAFFICGEN_IXIA_CARD = ''
   
   TRAFFICGEN_IXIA_PORT1 = ''
   
   TRAFFICGEN_IXIA_PORT2 = ''
   
   TRAFFICGEN_IXNET_LIB_PATH = '/opt/ixnetwork/lib/IxTclNetwork'
   
   # IxNetwork host IP address
   TRAFFICGEN_IXNET_MACHINE = ''
   TRAFFICGEN_IXNET_PORT = ''
   TRAFFICGEN_IXNET_USER = ''
   TRAFFICGEN_IXNET_CHASSIS = ''
   
   # The result directory on $TRAFFICGEN_IXNET_MACHINE
   TRAFFICGEN_IXNET_TESTER_RESULT_DIR = ''
   
   # The result directory on DUT. This needs to map to the same directory
   # as the previous one
   TRAFFICGEN_IXNET_DUT_RESULT_DIR = ''
   
   TRAFFICGEN_IXNET_TCL_SCRIPT = 'ixnetrfc2544.tcl'
   

2. sharing results between windows server (where IxNetwork TCL Server is running) and DUT (where VSPERF is executed); The recommended approach is to create a directory dedicated to results, share it from windows and mount it via samba/cifs at DUT.
   • create directory for results at IXIA GUI, e.g. c:\ixia_results and put this path into VSPERF configuration file as follows:

     TRAFFICGEN_IXNET_TESTER_RESULT_DIR='c:/ixia_results'

   • share this folder (with everybody)
   • create a mount point at DUT, e.g.

     sudo mkdir /mnt/ixia_results

     and put this path into VSPERF configuration file as follows:

     TRAFFICGEN_IXNET_DUT_RESULT_DIR = '/mnt/ixia_results'

   • ensure that cifs-utils are installed
   • mount directory with ixia results manually or put a new entry into /etc/fstab so it is mounted automatically during the boot, e.g.

     mount -t cifs //_WINDOWS_SERVER_IP_OR_FQDN_/ixia_results /mnt/ixia_results -o file_mode=0777,dir_mode=0777,nounix
