Testing Multicast Connectivity

To test the ability to receive multicast traffic on a specific LAN segment, you can use the CSPAN feed, which can be found at http://www.i2-multicast.northwestern.edu/. Otherwise, to test the specific 3CMedia streams you can test with VLC player by following the instructions below.  The 3C Media Solutions channel streams are always active.  Video and audio is always present and should be seen and heard once your multicast configuration connectivity is configured correctly.

Using Older VLC versions 0.9.4 through 1.0.5
Connect you laptop or PC to a network segment that is multicast enabled, with a route back to the CENIC router.

Launch the VLC player from the desktop icon or shortcut.

Click on Media and select Open Network… or Open Network Stream

For the protocol, select UDP

Enter the 3CTV stream multicast address 233.25.92.1
