tailieunhanh - Modular QoS CLI Service Policy

This module describes the policy part of the Modular QoS CLI (MQC). The module describes all the mechanisms that are currently supported by the MQC. As well, the module describes the class-based approach to the marking, shaping, policing, dropping and/or scheduling of IP packets using the modular QoS CLI. | 9 Modular QoS CLI Service Policy Overview This module describes the policy part of the Modular QoS CLI MQC . The module describes all the mechanisms that are currently supported by the MQC. As well the module describes the class-based approach to the marking shaping policing dropping and or scheduling of IP packets using the modular QoS CLI. Objectives Upon completion of this module you will be able to perform the following tasks Describe the policy part of the Modular QoS CLI Configure packet marking with modular CLI Configure policing and shaping with modular CLI Configure class-based WFQ with modular CLI Configure congestion avoidance mechanisms WRED with modular CLI Configure low-latency queuing Monitor and troubleshoot policy maps Service Policy Overview This lesson introduces the part of the MQC that is used to enable QoS mechanisms for classified traffic. Objectives Upon completion of this lesson you will be able to perform the following tasks Describe and configure policy maps. List all the QoS mechanisms currently available in the MQC. Monitor and troubleshoot policy maps. 9-2 IP QoS Modular QoS CLI Service Policy Copyright 2001 Cisco Systems Inc. One aspect of modularity of the MQC is the configuration part MQC is split into two modules - Configuration of classification - Configuration of service policies Classification is configured by using class maps Service Policy is configured by using policy maps 2001 Cisco Systems Inc. IP QoS Modular QoS CLI Service Policy-5 The Cisco IOS Modular QoS CLI MQC is the new unified method of QoS mechanism configuration in Cisco IOS. MQC separates classification and QoS mechanism configuration by separating the configuration tasks into Configuration of class-maps which define the classification of traffic Configuration of service policies which define how QoS mechanisms are applied to traffic classes This creates a flexible environment for the modular configuration of many QoS features and significantly reduces
