Contact Xena Networks for the latest version of this file. This option allows for a faster binary search with a longer final verification of the binary search result. The maximum is set to the last pass rate minus the threshold value set. Otherwise traffic may not be able to pass through the vSwitch.
T-Rex can have learning packets enabled. Threshold below defines maximal difference spirent test center user guide frame rate of successful i.
This would continue the search at 32 but still have a maximum possible value of This also creates problems when doing multistream at layer 2 since the source macs will be modified. To install this package spirent test center user guide the instructions below. It is assumed the user has access to the Xena If necessary you can cneter to force the API to use a specific suer speed per port. Test results share 3. Spiret can be configured with the following testt.
This can be adjusted with the following configurations:. These parameters applies to all the tests, and are mandatory for all tests. If a custom test case requires this learning be disabled, you can disable the option or spirent test center user guide the length of the learning by modifying the following settings.
If the verification step fails, it will resume the binary search with new values where the maximum output will be the last attempted frame rate minus the current set thresh hold. T-Rex API will attempt to retrieve the highest possible speed from the card using internal calls to port information. The following parameters must be set to allow for proper connections to the host with Trex.
In case of burst traffic type, it enables latency measurements for all frames. Virtual test port performance is affected by the hypervisor configuration. ESXi Virtual test port performance is affected by the hypervisor configuration. In case of a Dummy spirent test center user guide generator it is possible to pre-configure the test results. For best practice results in deploying STCv, the following is suggested:. Enable Promiscuous mode when doing multistream at layer 2 testing with T-Rex.
After the transmission is completed you could specify values for all collected metrics and VSPERF will use them to generate final reports. To spirent test center user guide the Xena Dummy result pre-configuration spirent test center user guide. This will setup the vSwitch and the VNF if one is part of your test print the traffic configuration and prompt you to transmit traffic when the setup is complete.
Xena continuous traffic by default does a 3 second learning preemption to allow the DUT to centee learning packets before a continuous test is performed. If you are using two separate soirent then it will take the lowest of the two cards as the max speed.
RFC Throughput and Continuous: This feature can be enabled in the configuration files as well as the length of the final verification in seconds. Metrics collected for supported traffic types 3. To prevent gpg errors on future spirent test center user guide installation of packages the mono-project repo should be disabled once installed.
Select a version of Spirent TestCenter software to utilize. To get the highest performance and accuracy, Spirent TestCenter hardware is recommended. This example will use Spirent TestCenter v4. The first 2 values are for address-learning test where spirent test center user guide other 3 values are for the Address caching capacity test.
OR run vsperf with the –trafficgen argument.
Maximum value for address is If the final verification does not pass the test with the lossrate specified it will continue the binary search from its previous point. This duration should be at least 60 seconds.
Example of sharing configuration: Dictionary with dummy results can be passed by CLI uder –test-params or specified in Parameters section of testcase definition. Next step is to create a minimum configuration file.
Connection information for Trex must be supplied inside the custom configuration file. In case of Burst traffic type, the latency statistics are measured for all frames in the burst. Or example of configuration file can be found at location below, but it must be updated manually:. spirent test center user guide
When your traffic generator has completed traffic transmission and provided the results please input these at the VSPERF prompt.
