https://community.extremenetworks.com/t5/extremewireless-general/nac-and-ewc-radius-timeouts/m-p/31959#M828 Hey guys,<BR /> I rebooted one of our NAC Appliances after turning off the dns Proxy. Now I'm getting the following error when the NAC tries to process RADIUS Requests from both our wireless controllers: <BR /> <BR /> 2016-01-22 09:33:32,144 WARN [NacAlertManager]Asserting: Error Detected for RFC 3576: 10.101.110.12: Reauthentication Failed:<BR /> Timeout<BR /> 2016-01-22 09:34:39,590 ERROR [RadiusClient] communication failure (timeout), no more retries<BR /> <BR /> The "Verify RADIUS Configuration" on the NAC Appliance shows: "RADIUS Servers inconsistent".<BR /> <BR /> I've tried deleting and readding the servers both in the NAC and the EWC with the same result. Now MAC authorization from the wireless controller doesn't work anymore because the Reauth results in a timeout.<BR /> <BR /> NAC version 6.2.0.224, EWC version09.21.01.0179.I hope you guys have some suggestions for me! thanks in advance<BR /> <BR /> Fri, 22 Jan 2016 16:20:00 GMT Johannes_Dennin 2016-01-22T16:20:00Z https://community.extremenetworks.com/t5/extremewireless-general/nac-and-ewc-radius-timeouts/m-p/31959#M828 Hey guys,<BR /> I rebooted one of our NAC Appliances after turning off the dns Proxy.
