Product and Software: This article applies to all Aruba controllers and ArubaOS 3.3.2.x and later.
This article describes what might happen if you do not use unique cluster names.
If you create a mesh network in a busy RF area, sometimes it may not work.
If another mesh network is installed close by, check to see if any errors were made on that other installation.
Try this experiment: take the first installation down, and notice that the new one now works. If you try to bring the first installation back up, it does not work as long as the other installation is up.
After some troubleshooting, the problem is found. If you keep all the default parameters in the mesh cluster profile, mesh APs from different installations form adjacency with others.
To prevent mesh networks from forming unintended neighbors, follow these rules:
- Always use a unique cluster name.
- Always use encryption.
