Class-Based QoS Usage report reveals class-based quality of service (CBQoS) metrics within your network. This report indicates the effectiveness of class-based policies applied for specific traffic classes, which are used to prioritize and shape network traffic. Note that class-based policies can be applied to specific interfaces and traffic direction.

The "class" in CBQoS is actually an NBAR classification (designated by rules applied at the router). NBAR classification rules at the router can identify a traffic stream by different criteria such as interface, port, and so on.

Class-Based QoS Usage chart data reflect the following:

  • QoS Class Map. Displays the QoS class name as defined by the policy assigned to the interface.
  • Pre-Policy. Displays the amount of traffic for the class before the policy is applied (for the selected date range).
  • Post-Policy. Displays the amount of traffic for the class after the policy is applied (for the selected date range).
  • Dropped. Displays the number of bytes dropped as a result of applying the policy to the class (for the selected date range).

Understand column data

The default view of each report contains a grid with the following columns:

  • QoS Class. Traffic class.
  • Policy. Policy applied.
  • Definition. Policy rules.
  • Source. Flow source.
  • Interface. Network interface.
  • Direction. Traffic direction across the interface (In/Out). Bounced traffic is not considered.
  • Pre Policy. Pre-policy bandwidth.
  • Pre Policy Rate. Pre-policy observed rate.
  • Post Policy. Post-policy bandwidth.
  • Post Policy Rate. Post policy observed rate.
  • Dropped. Dropped volume.
  • Dropped Rate. Rate observed where traffic was dropped.
Note: You must have defined QoS classes and policies on the source device before this report is able to display results.

Note: The CBQoS information generated by the source device must be gathered using SNMP polling for CBQoS information.
