DSL subscribers. Depending on their VPI, the customers get applied to
a VC-Class where the UBR speed is set. (256kb, 1.5mb, 5mb,
etc.) We only shape/police the downstream while the DSLAM shapes/polices
the upstream.</FONT></SPAN></FONT></SPAN></DIV>

process of implementing Calix DSLAMs that will be connected via Ethernet
rings to Cisco 7609's. There we will hand off the traffic via Layer-2
vlans to our Cisco 10008 DSL Aggregator for PPPoE termination. We were
trying to figure out the best way to shape/police the customers for their
purchased bandwidth. Our Cisco Sales Engineer said that we can create
service-policies on the 10008 and use a radius attribute to point those
customers to those service policies. I'd like to know if this is the best
option and how well it scales for 1000's of customers. We don't want to
shoot ourselves in the foot by using a method that will start to tax the CPU on
our router and cause degradation of service to
others.</FONT></SPAN></SPAN></FONT></SPAN></DIV>
