This optional parameter allows you to set up different
charging bands for different levels of port occupancy in this group of
users. You can have one or more ClassForSession- Limit lines. If the
current level of port usage is below a ClassForSessionLimit, then the
class name will be applied as a Class attribute to that session. Your NAS
will then tag all accounting records for that session with the Class
attribute. If your billing system records and uses the Class attribute in
accounting records, then you could use this to charge differently for
different levels of port occupancy.
# The first 2 users will be tagged with a Class of "normal"
