First, do you have any NAC Appliances added to the system? I don't see any in your screenshot to the left of the picture.<BR /> <BR /> Second, Lost-Carrier generally means that RADIUS accounted reported that the end system was disconnected. Lost-Carrier I think is generally for wired switches when the end system disconnects.<BR /> <BR /> Can you provide more info about your environment and how it's configured?<BR /> <BR /> Thanks,<BR /> <BR /> Tyler Wed, 03 Feb 2016 21:15:00 GMT https://community.extremenetworks.com/t5/extremecloud-iq-site-engine/end-system-unable-to-connect-into-network/m-p/42917#M5582 TylerMarcotte 2016-02-03T21:15:00Z https://community.extremenetworks.com/t5/extremecloud-iq-site-engine/end-system-unable-to-connect-into-network/m-p/42918#M5583 Hi Mir Ali,<BR /> Do you still need assistance with this issue?<BR /> Wed, 17 Feb 2016 04:22:00 GMT https://community.extremenetworks.com/t5/extremecloud-iq-site-engine/end-system-unable-to-connect-into-network/m-p/42918#M5583 Drew_C 2016-02-17T04:22:00Z
