What constitutes a connection?

  • 1.  What constitutes a connection?

    Posted Mar 22, 2012 12:36 AM

    The problem was that we were seeing a large number of "connections", exceeding the max values for each radio on an access point.  The age on these connections varied from minutes to several days old.  We are running 6.1.3.1 Aruba OS on a test controller, and I observed that the connection count for the AP on the gui showed 144bg/3a connections, Airwave reported 62bg/2a connections, and the controller showed only 1 active client on the AP (gui and CLI).  Which number does the AP use to determine when the maximum number of connections (in this case 64) has been reached, and why do the number of connections reported by the gui and Airwave vary?  I would expect stale entries to be flushed, yet the number of connections occasionally decreases only by a few at best.  Can someone help me understand what is being reported as a connection?

    A connection is a device that is connected to the controller that consumes an ip address.

     

    Please type the output from "show aaa timer".

    Thanks for the reply.  Attached is the requested info:

     

    #show aaa timer

    User idle timeout = 60 seconds
    Auth Server dead time = 10 minutes
    Logon user lifetime = 1 minutes
    User Interim stats frequency = 600 seconds

    What version of code is this and are the clients using encryption?

    We are running v6.1.3.1 upon recommendation from Aruba support.  We were also seeing the problem on v6.0.2.1.  There are three SSIDs on each radio, one uses encryption, the others do not.   All use forward mode of tunnel encrypted.

    Please open a TAC case to see if they can narrow down the issue.

     

    This should not happen.
