How to control users traffic ?

There are no standard radius attributes for this. Your NAS might have
vendor specific attributes that can be used for data (sql)counters but
many don't.

Again, this will depend on NAS supporting PoD or CoA. You can make a
policy that sends instructions to NAS to disconnect the user if he goes
over the limit on update packet. If it doesn't, you should still be able
to disconnect the user using SNMP.

If it has such VSA. You can then use standard (sql)counter.
