Hit Ok and start the TCL server application +VSPERF configuration +~~~~~~~~~~~~~~~~~~~~ + +There are several configuration options specific to the IxNetworks traffic generator +from IXIA. It is essential to set them correctly, before the VSPERF is executed +for the first time. + +Detailed description of options follows: + + * TRAFFICGEN_IXNET_MACHINE - IP address of server, where IxNetwork TCL Server is running + * TRAFFICGEN_IXNET_PORT - PORT, where IxNetwork TCL Server is accepting connections from + TCL clients + * TRAFFICGEN_IXNET_USER - username, which will be used during communication with IxNetwork + TCL Server and IXIA chassis + * TRAFFICGEN_IXIA_HOST - IP address of IXIA traffic generator chassis + * TRAFFICGEN_IXIA_CARD - identification of card with dedicated ports at IXIA chassis + * TRAFFICGEN_IXIA_PORT1 - identification of the first dedicated port at TRAFFICGEN_IXIA_CARD + at IXIA chassis; VSPERF uses two separated ports for traffic generation. In case of + unidirectional traffic, it is essential to correctly connect 1st IXIA port to the 1st NIC + at DUT, i.e. to the first PCI handle from WHITELIST_NICS list. Otherwise traffic may not + be able to pass through the vSwitch. + * TRAFFICGEN_IXIA_PORT2 - identification of the second dedicated port at TRAFFICGEN_IXIA_CARD + at IXIA chassis; VSPERF uses two separated ports for traffic generation. In case of + unidirectional traffic, it is essential to correctly connect 2nd IXIA port to the 2nd NIC + at DUT, i.e. to the second PCI handle from WHITELIST_NICS list. Otherwise traffic may not + be able to pass through the vSwitch. + * TRAFFICGEN_IXNET_LIB_PATH - path to the DUT specific installation of IxNetwork TCL API + * TRAFFICGEN_IXNET_TCL_SCRIPT - name of the TCL script, which VSPERF will use for + communication with IXIA TCL server + * TRAFFICGEN_IXNET_TESTER_RESULT_DIR - folder accessible from IxNetwork TCL server, + where test results are stored, e.g. ``c:/ixia_results``; see test-results-share_ + * TRAFFICGEN_IXNET_DUT_RESULT_DIR - directory accessible from the DUT, where test + results from IxNetwork TCL server are stored, e.g. ``/mnt/ixia_results``; see + test-results-share_ + +.. _test-results-share: + +Test results share +~~~~~~~~~~~~~~~~~~ + +VSPERF is not able to retrieve test results via TCL API directly. Instead, all test +results are stored at IxNetwork TCL server. Results are stored at folder defined by +``TRAFFICGEN_IXNET_TESTER_RESULT_DIR`` configuration parameter. Content of this +folder must be shared (e.g. via samba protocol) between TCL Server and DUT, where +VSPERF is executed. VSPERF expects, that test results will be available at directory +configured by ``TRAFFICGEN_IXNET_DUT_RESULT_DIR`` configuration parameter. + +Example of sharing configuration: + + * Create a new folder at IxNetwork TCL server machine, e.g. ``c:\ixia_results`` + * Modify sharing options of ``ixia_results`` folder to share it with everybody + * Create a new directory at DUT, where shared directory with results + will be mounted, e.g. ``/mnt/ixia_results`` + * Update your custom VSPERF configuration file as follows: + + .. code-block:: python + + TRAFFICGEN_IXNET_TESTER_RESULT_DIR = 'c:/ixia_results' + TRAFFICGEN_IXNET_DUT_RESULT_DIR = '/mnt/ixia_results' + + Note: It is essential to use slashes '/' also in path + configured by ``TRAFFICGEN_IXNET_TESTER_RESULT_DIR`` parameter. + * Install cifs-utils package. + + e.g. at rpm based Linux distribution: + + .. code-block:: console + + yum install cifs-utils + + * Mount shared directory, so VSPERF can access test results. + + e.g. by adding new record into ``/etc/fstab`` + + .. code-block:: console + + mount -t cifs //_TCL_SERVER_IP_OR_FQDN_/ixia_results /mnt/ixia_results + -o file_mode=0777,dir_mode=0777,nounix + +It is recommended to verify, that any new file inserted into ``c:/ixia_results`` folder +is visible at DUT inside ``/mnt/ixia_results`` directory. + Spirent Setup ------------- |
