Check for interface drops on WLAN controller

  • 1.  Check for interface drops on WLAN controller

    Posted Oct 29, 2015 05:41 PM

    Is there a command to see output drops on a WLAN controller due to contention on an uplink?  A Cisco switch would show it using the 'show int if#/#' command, but on an Aruba controller I don't see an 'output drop' count.  Just need to figure out how often some 1Gb links are getting overrun.

     

    Thanks.

    The only option is to use the show port statistics but it only shows if there's any output or input error

    Right, which is something different. Hard to believe this isn't available.

    Thanks.

    If you have Airwave, it is monitoring the throughput on a controller, batched every 5 minutes, of course.

     

    If there is indeed congestion, in "show log system 100" you would see rebootstraps.

     

    Lastly, the back-of-the napkin size of an uplink should be one gigabit ethernet interface for each 100 access points.
