RUCKUS Team Member

This article explains how to replace Radius Certificate on Cloudpath if expired.

In many occasion you will see Customer has reported an issue with Radius authentication with Cloudpath server, all authentication requests will fail, from Cloudpath point of view you can identify the issue if the radius certificate is expired or not.

For client troubleshooting and pcap one can identify if the radius certificate is not trusted by the client, that also leads to certificate expiry or change in radius certificate.

Do not change the certificate comman name.
If CA is external make sure, the certificate is assigned by same CA.

All existing user authentication will fail in case above is not followed.

Steps to verify on Cloudpath:

  • Verify if the Radius certificate is expired.>>>Cloudpath GUI>>>Configuration>>>Radius Server

  • Scroll down and Click on Actions: Replace Certificate


    Very Few Customer uses External CA for Radius Certificate, Validate the Root Certificate of the expired Certificate, for External CA the steps are given at the end.
  • Select Generate New Certificate Automatically, if you have not imported the previous certificate from external CA.

    >Certificate Template: will be  selected as Server Template.
    >Server Name: will be prefilled with the previous name, make sure it stays same as earlier.
    >Years Valid: will be prefilled with the 3 Years, can be extended up to 5 Years.
