Dears,
I need urgent support, I spent like 12 hours troubleshooting a wireless issue on my Cisco WLC 9800 for .1x authentication that was working & suddenly stopped.
The software code is 17.9.4a & 17.12.1
Here’s the logs on the WLC:
Feb 4 16:16:34.041: %DOT1X-5-FAIL: Chassis 1 R0/0: wncd: Authentication failed for client (8086.f285.a2f5) with reason (AAA Server Down) on Interface capwap_90000016 AuditSessionID 17DC140A00000010C5851691 Username: 123456
Feb 4 16:16:34.041: %SESSION_MGR-5-FAIL: Chassis 1 R0/0: wncd: Authorization failed or unapplied for client (8086.f285.a2f5) on Interface capwap_90000016 AuditSessionID 17DC140A00000010C5851691. Failure reason: Authc fail. Authc failure reason: Credential Failon
The strange thing is wireshark on NPS showing zero packets received from WLC.
I do confirm all the configuration is correct & nothing changed.
I rebooted WLC many times with no success.
Using NTRadping giving successful authentication.
Is the RADIUS service on the WLC destroyed or what noting that “show aaa servers detailed” showing all WNCD are up but showing 0 in the authentication request count all the time.
Thanks,
