high values of "retried frames" to client and from client

    On WEB dashboard of WLC Aruba7220 I see high values of "retried frames" to client and from client, here is part of it:

    Are these values correspond to what is actually happening (as sometimes client score shows "good" , but such retry counter is quite high) ?!
    How can I reduce such values ?!

    That 188% looks like a bug to me.
    Retried frames are typical in a shared medium like wireless
    The percentage is site and location specific
    Some bandwidth and latency applications like voice require that retries be a low at 4% to be effective, but QOS can help this.

    Some clients do not send much traffic, so if they send 3 frames and 2 are retries, those are 66% retries.  I would not rely on retries alone to determine the health of the client. I would use things like goodput and health.

    Any opinions expressed here are solely my own and not necessarily that of Hewlett Packard Enterprise or Aruba Networks.
