Point-to-Point Mesh dropping with AP-175

  • 1.  Point-to-Point Mesh dropping with AP-175

    Hello,

     

    I installed a point-to-point wireless mesh using the Aruba AP-175's for a customer about three years ago. The link has run flawlessly transporting data and VoIP traffic up until about a few months ago when the VoIP phones at the remote end of the link started dropping calls and losing connectivity to the phone system for brief periods of 15-30 seconds. Just long enough to cause calls to drop but within 15-30 seconds the phones are active again.

     

    I've looked all the obvious things such as losing power to the AP-175's at either end, the Aruba controller that manages the Mesh going down etc. With all those items ruled out, I'm wondering if there is a way from the controller (Aruba 3400) CLI to debug or monitor the mesh link that might provide me with information as to what is causing the intermittent drops. 

     

    The AP-175's are about 500 yards apart from one another with a clear line of site. As I stated, they have performed well for ~ 3 years up until a few months ago.

     

    Any information on how I might debug this mesh link would be greatly appreciated.

     

    Thanks,

     

    John

    From your description, it sounds most like something environmental has changed, possibly in the interference environment.

     

    Can you please capture the output of these commands and email to chuck@arubanetworks.com?

     

    show tech-support

    show ap debug radio-stats ap-name <PORTAL> radio 0 advanced

    show ap debug radio-stats ap-name <POINT> radio 0 advanced

     

    substitute the appropriate AP names in the two debug commands.

     

    thanks.
