COTD: Mesh: Make sure that your mesh cluster name is different every time

You hooked up mesh with Aruba and now you're a pro at it. All of a sudden, you hook up a mesh network in an RF busy area and it does not work. It so happens that you have another mesh install not too far away, so you take a look at that to see what you might have done wrong on that other install. Just for kicks, you take the first install down, but now the other one works! You try to bring the install back up and it will not work as long as the other one is up. After some troubleshooting, you realize that mesh APs from other installations form adjacencies with others, if you don't change any of the default parameters in the Mesh Cluster Profile.

In the Mesh Cluster Profile, always pick a unique Cluster Name (this is how cluster members find each other) and always use encryption. Both of these tips will keep mesh networks from forming unintended neighbors.:
