BYOD user is able to connect SSID but webpage redirection not happenin

[Rajesh Kumar Reddy]

Hello Team,

I have an issue with BYOD authentication as user is able to connect with SSID and receive IP address but webpage redirection is not happening and Logs shows L3 authentication failure.

WLC: C9800

Authentication server: Clearpass.

Attaching the logs for one of the client where debug logs were captured. Can someone give me what to check and how to resolve this.

Note: Out of 3 branches other two branch users does not have an issue and it is issue with only one branch users.

3 branches have 3 WLCs and Clearpass is running in cluster mode(Publisher subscriber model).

Regards,

P R Kumar

  - Feed those attached debugTrace(s) into : Wireless Debug Analyzer
    to get a high level analysis of what is happening (one by one  , not all together)
    You may need to check the Show All flag on the right when the result appears ,

  - Also use these info's for further debugging : https://logadvisor.cisco.com/logadvisor/wireless/9800/9800CWA

   + It's always advisable to have an overall checkup of the 9800 controller configuration with the
     CLI command show  tech wireless (not a simple show tech) and feed the output from that into
                                       Wireless Config Analyzer

   + When changing are made in the controller's configuration then run WirelessAnalyzer again
      Also use https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/217738-monitor-catalyst-9800-kpis-key-performa.html#anc5
      to get an overall idea on client behavior,
