How to check the logs when an Access Point went off-line

    Hello,

     

    We have had some power outages that forced Our Aruba IAP-325 to go down and then back up.  Is there a way to view the logs when these AP's went down?  These Access Points are in Capus mode and are connected to 2 local controllers and ultimately to a Virtual mobility master.

     

    How can we look at the logs regarding a campus mode Access Point?  Again these AP's are provisioned in Campus mode and tied to a VIP of the local controllers.

    Thius far, I have discovered.

     

     
    1. Login to the web UI for the controller.
     
    2. Then Navigate to:
    a. 'Diagnosis' - 'Access Point' - 'System Status' - 'AP Name'.
     
    3. Type in the AP Name and then click on the 'Show Status' button.
     
    4. The displayed information includes many topics:
    a. Last Reboot Information.
    b. AP Uptime
    c. Messages from AP to controller.
    d. Crash information, memory usage, etc.
    e. ARP Cach, route table, etc.

    Airwave will show "last seen at" times, but the controller does not track the last seen time of any AP unfortunately (at least that I have never found...)

     

    You could also use SNMP trap collection to determine it as a trap is sent when an AP goes down or up.

     

    The method you describe for determining what happened to an AP that went away and then came back is correct (but it of course relies on the fact the AP didnt go away permanently).
