12708 -- IxLoad port ownership, reset, release

iTest IxLoad sessions do not have options or properties to perform the following actions:

• Take port ownership before launching the test
• Reset ports before launching the test
• Release ports when test finishes

As a result, closing an IxLoad session can crash ports. According to Ixia, this is because iTest is not performing an unconfigure action before releasing the session. Failing to do this leaves the ports in an indeterminate ownership state. If you try closing the IxLoad GUI without unconfiguring, multiple warnings result.

Solution:

You must perform any of these operations in the IxLoad test itself. Use the IxLoad UI application to configure the actions.

Each test contains boolean properties like:

enableForceOwnerShip - If true, at the beginning of the test, any ports that are selected for the test but owned by another user are rebooted and their previous ownership cleared. This parameter corresponds to the GUI option "Forcefully Take Ownership." (Default = false).
 
enableResetPorts - If true, IxLoad reboots the ports before downloading the test configuration to them. To ensure the integrity of your testing, it is always safest to reboot the ports before running a test. However, rebooting the ports does increase the amount of time required to prepare the ports for a test.
 
enableReleaseConfigAfterRun -If true, purges the test configuration from the ports after a test completes, releases ownership of them, and the ports will no longer respond to ARPs and PINGs from the DUT. (Default = false).
