After some "behind the scenes" wrangling, we've managed to get some new values defined for Acct-Status-Type. These values are especially useful to vendors who have one RADIUS client which controls multiple subsystems. i.e. a WiFI Access Point, where all of the RADIUS packets come from the controller, but each individual radio may have many users. If the radio reboots while the controller is still up, there was no way in RADIUS for the controller to signal that. It would have to send multiple accounting packets, one for each user on that controller. With the new values defined, the controller can just say "subsystem 1 stopped". The new values are defined here: https://www.iana.org/assignments/radius-types/radius-types.xhtml#radius-type... A longer discussion of the issue is on the main FreeRADIUS page: https://freeradius.org/rfc/acct_status_type_subsystem.html I encourage people to forward these links to vendors, so that vendors can start implementing this new functionality.
