Accounting sessions are managed by the NAS and distinguished by Acct-Session-Id etc., so, you can’t really unless your NAS can do this - but I’ve never seen such a “feature”.

Often we return a “Class” in an Access-Accept message, which is included in Accounting requests and is what FreeRADIUS uses to distinguish unique sessions. **Maybe** you can update Class in a CoA, but, that would almost certainly be NAS specific. Additionally, this would not cause the NAS to reset the counters to zero, nor send an accounting start type message.

This is quite a specific question - short answer is “you can’t” - but perhaps we can help if we know what you are doing. What are you looking to achieve? Why do you want new accounting sessions?
