Reporting on Cisco CBQoS

What is CBQoS?

CBQoS (Class Based Quality of Service) is a Cisco feature set that is part of the IOS 12.4(4)T and above. This provides information about the QoS policies applied and class based traffic patterns within an enterprise's network. 

Why do you need it?

A network manager’s top priority is to ensure that the business critical applications get the optimum priority. Typically, networks operate on the basis of best-effort delivery, in which all traffic has equal priority and an equal chance of being delivered. When congestion results, all traffic has an equal chance of being dropped. Or, in case a particular traffic is to be prioritized, appropriate QoS policies can be applied as per the requirement.

Network administrators implement QoS policies to ensure that their business-critical applications receive the highest priority on the network. CBQoS can make network performance more predictable and bandwidth utilization more effective. CBQoS provides you in-depth visibility into the policies applied on your links and the traffic patterns in your various class of traffic.

How can NetFlow Analyzer help you?

ManageEngine NetFlow Analyzer supports Cisco CBQoS and thus reports on the QoS policies that you have deployed. The report shows the pre-policy, post-policy and drops in different traffic class along with the queuing. This enables you to validate the QoS policies. You can change your policies according to the reports, which you see in NetFlow Analyzer. This is a tool, which can be best used for QoS policy validation.
