Cisco CBQ-MIB Browser Module

CBQ-MIB Browser comes standard with OiDViEW Enterprise.

Cisco CBQ (CLASS-BASED-QOS) Browser Overview

The CISCO-CBQ Browser Module is the latest addition to our network management arsenal. Cisco leads the network management industry in its' robust and widely implemented Quality Of Service (QOS) technology. Their CISCO-CLASS-BASED-QOS-MIB uses a complex system of policies and traffic classes to define and control traffic flows. As such, implementation of these traffic flows can get sophisticated and often confusing as they are usually configured with the Cisco Command Line Interface (CLI). Now, a new tool exists, the OiDViEW Cisco CBQ Browser Module, which will allow one to verify these complex configurations via SNMP and see visually what their changes have done to the hierarchical QoS configuration.

If a MIB Browser session is created, OiDViEW will look for the presence of the CISCO-CLASS-BASED-QOS-MIB in the agent. If it exists, the CBQ Browser button will be enabled on the session detail toolbar. This will enable the user to launch the CBQ Browser and see the current QoS configuration on the router. Once changes have been made, the visual display can be refreshed and the new configuration will represented graphically. This is a fantastic way to quickly verify configuration changes.

CBQ Browser breaks down the QoS configuration into Service Policies, Traffic Classes, and QoS objects. Click on any of these items on the right and they will be highlighted in the hierarchical graphical display on the left.

The OiDViEW CBQ Browser is not currently a substitute for Cisco QoS Manager, Device Manager, or Cisco Policy Manager (as it is only a Browser and not a configurator), but for users of Cisco IOS without the Cisco Policy Manager, or network administrators doing verification of QoS configurations, this tool can be a lifesaver.

For more information on the CISCO-CLASS-BASED-QOS-MIB, please see Cisco's webpage on IOS QoS technology. They also have a detailed QoS primer, located here.
