I discovered that anytime the Uplink of my Cisco C2960CG-8TC-L goes down and reconnects, before the switch connects with the Radius Server, the access ports starts to connect into Guest VLAN, which is not the correct production VLAN that has been assigned to the Mac addresses.
I thought I could resolve this with Link state track Upstream and Downstream, but it's not working effectively.
The solution to the problem should be when the UPLINK port does down for whatsoever reason and comes back up, it should communicate with the Radius Server first, thereafter the access ports comes up and connect to the assigned Production VLAN not the Guest VLAN.
How do I achieve this? Any positive advise would be highly appreciated. Configuration can be uploaded if needed.

decision. To do this we require the switch to do...
