The Cisco Webex Network Test is performed to check the status of the customer network, specifically for the speed of the network using TCP and UDP, and port connectivity. The logs are used to validate whether the customers current settings are optimal to run Webex services or not.

If the Webex or Webex Telepresence service does not work as expected after activation, you can run the Line Quality Test Tool: The tool verifies that your Internet connection supports the Webex Telepresence service.

Before you begin, make sure that your web browser is Java-enabled and has Java Runtime Environment (JRE) 1.5 or above installed. To run the Line Quality Test tool using Internet Explorer (IE) on a 64-bit Windows machine, make sure that you select the 32-bit version of IE and 32-bit Java Runtime Environment. On a typical Windows 7 64-bit machine, IE displays two entries in the Start menu. Select Internet Explorer, not Internet Explorer (64-bit).

Note: This tool no longer supports Safari on a Mac; it only supports Firefox (28 and above) and Google Chrome (39 and above).

If your test gets stuck during the testing process, then it’s possible your anti-virus client may be blocking the test from occurring. Be sure to temporarily disable the network security features within your Antivirus client, then re-run the test. You may also need to restart your browser.
