Measures reported by CisQosClasMapStTest Classifying network traffic allows you to organize traffic (that is, packets) into traffic classes or categories on the basis of whether the traffic matches specific criteria. Classifying network traffic is the foundation for enabling other QoS features such as traffic shaping and traffic policing on your network. High-priority network traffic or traffic matching specific criteria can be singled out for special handling, and thus, help to achieve peak application performance. The goal of network traffic classification is to group traffic based on user-defined criteria so that the resulting groups of network traffic can then be subjected to specific QoS treatments. The QoS treatments might include faster forwarding by intermediate routers and switches or reduced probability of the traffic being dropped due to lack of buffering resources. The network traffic can be classified using the following steps:
If a class map is not created successfully, then the network traffic classification may not be defined as expected and the traffic cannot be matched to a specific class. Similarly, if the class map handles too much of traffic, then the performance of the application may degrade drastically. To avoid performance degradation, it is necessary to monitor the traffic on each class map so that the class map that is handling excessive traffic can be figured out. The CisQosClasMapStTest test helps administrators to monitor the network traffic specified for each class map. This test auto-discovers the class maps on the target Cisco Router and for each class map, monitors the amount of data transmitted/ received. This test also helps administrators figure out the packets transmitted through each class map and identify data drops instantly. Outputs of the test : One set of results for every source host. The measures made by this test are as follows:
