I set reply-name = Session-Octets-Limit in sqlcounter but freeradius sends Seesion-Timeout in reply with value equal to the deduct of octets used until now from check-name = Max-Input-Octets. How should change the session-timeout to Session-Octets-Limit in auth-reply? what does Session-Octets-Limit exactly do? I have no idea. It's an attribute *you* wanted to use. As a guess, it limits number of octets for the session.
How it is related to counters?
You would configure it as a reply-name.
I thought freeradius sends a value(is defined in DEFAULT) to the NAS and NAS limits users traffic to this value in each session.
That's without counters. If you use counter, you place check-name attribute-value pair in users (or as DEFAULT) entry. On connection attempt freeradius will count usage so far, deduct it from the limit (check-name attribute value) and pace the reminder as a value for reply-name attribute.
