An indication if one would like only aggregate Service Flow
information per Cable Modem to be recorded. In this case
the record will have a SFID of 0 and a blank Service Class
Name. The distinction between upstream and downstream will
however be maintained. The counters present in the metering
records in this case will be the aggregate. i.e., sum of all
upstream/downstream service flows. By default, this object
is false which means that the metering records will
contain service flow counter information for all service
flows per CM.
