4. Getting Started

This section explains how to get started using the Xena3918 to execute a few simple tests. The test configuration will consist of one multicast source port and two multicast destination ports. It will not use any unicast traffic ports.

  1. Start the Xena3918 application.

  2. Press the Add Chassis button in the menu bar. Enter the address and password of the Xena chassis you want to use. Press the OK button and wait until the application has successfully connected to the chassis.

  3. Locate the three ports you want to use in the left-most Physical Ports tree view, right-click them and choose the Add Port to Test Configuration. You can either select them one by one or perform a multiple-selection by holding down the Ctrl while selecting port ports with the mouse.

  4. Change to the Selected Ports panel. You should now see the three ports you have chosen to include in the test:

  • Set the role of the port you want to use as the multicast source port to MC Source.

  • Set the role of the two other ports to MC Destination.

  • Set the IP Address, Routing Prefix and Gateway Address for each of the ports.

  1. Change to the Test Configuration panel.

  • Leave the options in the General Test Options subpanel at their default values.

  • Change to the Test Types Selection and Configuration subpanel. Ensure that only the Group Join/Leave Delay, Aggregated Multicast Throughput and Multicast Latency tests are enabled (checked). Leave the options for all enabled subtests at their default values.

  1. Change to the Multicast Configuration panel.

  • Check the following options in the Multicast Flow Definition subpanel:

    • Ensure that the IGMP/MLD Version is set to a version supported by your DUT.

    • Check that the Start Address in the Multicast Address Range section is supported by your DUT. You will only need a single multicast group address for the selected tests.

    • Check that the Packet Rate option is set to a value which is sensible for your DUT.

  • Check that the selected protocol header segments in the Protocol Segments subpanel are sensible for your DUT. Note the following default field assignments:

    • The Ethernet Source MAC address will be set to the MAC address of the port.

    • The Ethernet Destination MAC address will be set to the multicast MAC address according to RFC 1112 Section 6.4.

    • The Source IP address wil be set to the address specified for the port.

    • The Destination IP address will be set to the multicast group address.

  1. Save your configuration by clicking the Save button in the toolbar or by pressing Ctrl-S on the keyboard. Provide a filename for the configuration when asked.

  2. Start the test by clicking the Start button in the toolbar.

  3. The Result Data panel at the bottom should not be shown automatically and will allow you to follow the progress of the tests.

  4. When all selected tests have completed the final PDF report should be opened in your default PDF viewer application.
