Hierarchical Class of Service in ACX5000
ACX5000 Series routers support hierarchical class of service at the physical interface
level. You can configure up to 8 queues per physical interface (port). Scheduling properties
can be applied at both physical as well as logical interface levels. Service providers will
be able to support hierarchical class of service at multiple levels to meet the service level
agreements and bandwidth allocations for subscribers.

Hierarchical Scheduling on the Physical Interface
By default, the queuing mode on all the physical interfaces in the ACX5000 line of routers
is 8 queues per physical interface (port). In the hierarchical scheduler mode, you can
configure up to 3 levels (physical interface, logical interface, and queues) of scheduling.
You can enable hierarchical scheduling by including the hierarchical-scheduler CLI
command under the interfaces hierarchy as shown below:

hierarchical-scheduler;
}
