What is CBQoS?
Cisco Based Quality of Service utilizes Cisco Class Maps, and Traffic Policies Visually showing how all Protocols traverse a given link. CBQoS shows traffic before and after Traffic Policies have been applied showing how much traffic was also dropped based on Traffic Policy Rules.
What is a Class Map?
The grouping of Protocols or Applications for the ability to then apply the group to a Traffic Policy.
This is the most Granular and what each item is listed as in the image.
What is a Traffic Policy?
A collection of one or multiple Class Maps with basic grouping, or going one step further to Packet Police and Packet Prioritization.
Traffic Policies must be applied to an interface
Policy is applied to an Interface with a direction of input or output to show the Direction shown under CBQoS Details.
PURPOSE OF THIS GUIDE: Showing how CBQoS and Traffic Shaping. Visually showing the traffic per protocol to ensure that any link does not become easily saturated when a user chooses to move lots of data. The configuration shown is an example on getting data shown.
PREREQUISITE: NBar2 for the Protocol List. How To: Setup Cisco NBar2 to see what sites are accessed.
The Flow process: Create Class Maps, assign Class Map to a Policy Map, then use the Policy map name on the Interface and direction of the Interface.
The Result of this setup:
Example Configuration:
CAUTION: Do not just take this example and implement. This configuration example is included to show how to segment traffic based on Protocols into different Class Map buckets; your network will most definitively will be different. If the network link is a WISP with less than 10Mbps, then this is perfect starter.

Go into Configuration Terminal
Start Creating and assigning Class Maps. I have created the following as an example:

Create Policy Map:
Cisco IOS Quality of Service Solutions Command Reference - Policy-Map - Cisco
Policy Maps allow you to set Packet Prioritization, Police to limit how much it can use then set a priority, or drop traffic as some of the few examples. The link above will go far more into detail.
In Configuration Terminal under the (Config) Area, create a Policy Map. Use the Name of the Class Map as Class <Class Map Name>

Assign Policy Map to Interface
Configuration Terminal
interface <InterfaceName>
service-policy <Input/output> <Policy Map Name>
(Required Step to see in NetFlow) Enable CBQoS in SolarWinds NetFlow:
Go into Settings> NTA Settings> Manually manage NetFlow sources and CBQoS Polling
Expand out the device, select the Checkbox under CBQoS for the Interface you Enabled
CBQoS data is polled using SNMP. Wait about 10-30 minutes for a good chunk of data to roll in.
