Wireless Access

Some Aruba documentation says that  ADP uses 224.0.82.11, other documentation says that the address used is 239.0.82.11 - which address is the coirrect one?

Where do you see it one way and where do you see it with the other?

The advanced troubleshooting course says 239 but an older AOS user guide says 224.

I would look at the most up-to-date AOS guide, because over time, there are corrections, of course.  http://www.arubanetworks.com/techdocs/ArubaOS_63_Web_Help/Web_Help_Index.htm#ArubaFrameStyles/AP_Config/Deploying_APs.htm

From a support point of view I could encounter controllers running any code version - Is the correct address the 224 or 239 or have they both been in use over different code versions?

It is 239.0.82.11 currently.  I cannot speak to the history.

It is 239.0.82.11 the correct address:

Here's a capture from the latest 6.3.x.x code
