Hierarchical QoS (HQoS) for 8x10G modules

Other traffic
Figure 14 on page 180 displays a Local VPLS HQoS model concurrently supporting non-customer
traffic, which is referred to as "other traffic". The customer traffic will always be queued and
scheduled through the customer portion of the Layer 2 HQoS scheduler irrespective of what
customer Layer 2 traffic is carrying. The "other queues" is used for non-customer traffic. That is,
traffic that is not explicitly mapped to an HQoS queue. The "other queues" supports 8
queues/levels of priority. For this kind of traffic, you can queue packets per priority level, as shown.
Note: Each priority level can be shaped independently and the other traffic as a whole can also be
shaped to a desired rate.
