    Hello People,

    I have an issue, the platform is 2 MM on Vmware, 2 MC 7210 and a Clearpass on Vmware.

    A few days a go, i realized that the uptime of the Radius server is flapping, this is showed by cli command "show aaa authentication-server radius statistics" when uptime is about 3 hours.

    There is a best practice about tiemout and retransmit configuration under Radius Configuration on Mobility Controllers?

    What you recommend to fix this problem?

    Thanks for your help

    Hi.

    Better community for such a question is Wireless Access 

    Did you check the status of RADIUS service on Clearpass? 

    Do you use RADsec?

    Check in Clearpass Event log if service is flapping.

    Is Clearpass server overloaded?

    If everything on Clearpass server looks ok, then you need to check the network connection between Clearpass and MCs.

    Best, Gorazd
