  I don't see why.  When the NAS sends a packet with Acct-Status-Type =
On or Acct-Status-Type = Off, it means that the NAS has rebooted.  And
therefore ALL user sessions on that NAS are no longer active.

  The RADIUS server is supposed to mark all of those user sessions as
terminated.

  If the NAS continues to keep a user session after it's sent an on/off
packet, then the NAS is broken.

  If the NAS doesn't send an Acct-Terminate-Cause, then FreeRADIUS can't
log one.  I suppose it could be set to NAS-Reboot... but that doesn't
make much difference.

  Is what expected?  You have at least two different questions there.
