After few hours of googling I think I understood. The only not clear thing: how freeradius deside to send a CoA message or not ?
Comments from sites-available/originate-coa:
# CoA packets can be originated when a normal Access-Request or # Accounting-Request packet is received. Simply update the # "coa" list: # # update coa { # &User-Name = "%{User-Name}" # &Acct-Session-Id = "%{Acct-Session-Id}" # &NAS-IP-Address = "%{NAS-IP-Address}" # } # # And the CoA packet will be sent. You can also send Disconnect # packets by using "update disconnect { ...". #
What is the "Simply update the "coa" list" means ? Changing of a site configuration in accounting section like this
update coa { User-Name = "%{User-Name}" Acct-Session-Id = "%{Acct-Session-Id}" NAS-IP-Address = "%{NAS-IP-Address}" }
and restart service ?
Will the CoA message be generated in response for every acct request of active sessions ? That has no sense...
Yes, in this case fr will reply for every acct packet. But , for example we send disconnect only for acct-update and also checking attrs in packet( class and some others)

I am trying to understand the conception of coa server. What functionality does it brings ? Is it a some kind of proxy ?
For example, I have a NAS server with configured coa port. I can send a disconnect request directly into it. If I configure a coa server on a freeradius server, will I be able to send a disconnect request to the freeradius instead and that is all?
Thanks in advance for your answers!
