In this post I will explain my best practices in using Aruba APs as an point to point link. This is based on using Aruba Instant in version 8.4 or higher. This will not cover meshing in a controller based environment.
I wrote this post, because in the last month I had a few customer facing problems with their point to point Access Point links. None of these problems were with the APs or Instant itself, but with the network environment or circumstances they were working in. My best practices below fix these problems.
These recommendations are applicable to all APs running Instant OS 8.4 or higher including the AP-387 with it's 60GHz 802.11ad radio.
