View CBQoS data in NTA

Class-Based Quality of Service (CBQoS) is an SNMP-based, proprietary Cisco technology available on selected Cisco devices that gives you the ability to prioritize and manage traffic on your network. Using policy maps, also known as policies, the different types of traffic on your network are categorized, and then given a priority. Based on assigned priorities, only specified amounts of selected traffic types are allowed through designated, CBQoS-enabled devices.

For example, you could define a policy map in which only 5% of the total traffic over a selected interface may be attributed to YouTube.

CBQoS policies can be simple or include nested policies.

Nested policies are traffic policies applied to a class of an already existing policy. They allow you to set rules for a class-specified type of incoming or outgoing traffic on an interface, thus enabling you to build up a complex approach to different traffic data. Nested policies simplify your job if you need to modify a policy. You just modify the policy and your changes are automatically applied on all devices using this policy.

For more information about configuring class maps for your CBQoS-enabled network devices, search CBQoS at www.cisco.com.

NTA does not currently provide a CBQoS configuration capability, but any node managed by NPM can be polled for CBQoS information. If SNMP polls of the MIB for monitored devices are unsuccessful for CBQoS OIDs, CBQoS widgets are automatically hidden because they are empty. For more information about enabling CBQoS polling for monitored devices, see Flow sources and CBQoS polling.

For CBQoS-enabled Cisco devices on your network, NTA can provide immediate insight into the effect of your currently enacted policy maps. For details on widgets available on NetFlow Interface Details views, NPM Interface Details views, and CBQoS Details views, see CBQoS widgets.
