Problem:

The following error messages are being reported in the log file.

W 03/18/20 06:25:45 05620 dca: 8021X client 000C2921E66B on port 18 assigned to
            initial role as downloading failed for user role
            Role_Based___Dyni....

W 03/18/20 06:25:45 05204 dca: Failed to apply user role
            Role_Based___Dynimic_SW__User_Role-3050-2_7Z4q to 8021X client
            000C2921E66B on port 18: user role is invalid.



Diagnostics:

When a switch is configured for downloadable User-Roles, the role is transferred using SSL protocol. These messages are reported when the switch is unable to download a role from a ClearPass server as a result of the HTTPS invalid certificate.



Solution

Verification of the HTPPS certificate transfer can be done by enabling debugging and executing the following CLI commands.

Core-Switch# debug destination session
Core-Switch# debug event
Core-Switch# show debug

Core-Switch(config)# radius-server host 10.0.106.101 clearpass

I 03/18/20 06:49:00 05811 CADownload: Successfully downloaded the certificate
            from 10.0.106.101 server

 

Verification of the certificate validation failure can be done by enabling debugging with the following commands.
