subscriber line level, by using the line ID information present in DHCP option 82 and the PPP tag.
Shaping sessions with a common line ID effects traffic shaping for a particular subscriber line. See
Example 1-3
Model F configuration requires three levels of shaping/queuing hierarchy on the BRAS or NPE –at the
Subinterface, Session and Class levels.
