Chapter 31 Configuring QoS Configuring System Classes Send feedback to [email protected] Note Policy maps can also be configured for interface service policies. However, different parameters are supported in these policy maps. See the "Configuring QoS on Interfaces" section on page 31-13. The following example shows how to enable optimized multicast for the default Ethernet class: switch(config)# policy-map s1 switch(config-pmap)# class class-default switch(config-pmap-c)# multicast-optimize The following example shows how to create a policy map with a no-drop Ethernet class: switch(config)# class-map ethCoS4 switch(config-cmap)# match cos 4 switch(config-cmap)# exit switch(config)# policy-map ethNoDrop switch(config-pmap)# class ethCoS4 switch(config-pmap-c)# pause no-drop Creating the System Service Policy The service-policy command is used to associate the system class policy-map as the service policy for the system. Step 1 Step 2 Step 3 Command switch# configure terminal switch(config)# system qos switch(config-sys-qos)# service-policy name Purpose Enters configuration mode. Enters system class configuration mode. Specifies the policy-map to use as the service policy for the system. The following example sets a no-drop Ethernet policy map as the system class: switch(config)# class-map ethCoS4 switch(config-cmap)# match cos 4 switch(config-cmap)# exit switch(config)# policy-map ethNoDrop switch(config-pmap)# class ethCoS4 switch(config-pmap-c)# pause no-drop switch(config)# system qos switch(config-system)# service-policy ethNoDrop System Class Example In the following example, a new Ethernet no-drop system class is created, and the CoS values of the default system classes are changed from their default values: switch(config)# class-map trading-data-no-drop switch(config-cmap)# match cos 5 switch(config)# class-map class-fcoe switch(config-cmap)# match cos 2 switch(config)# policy-map system-policy switch(config-pmap)# class trading-data-no-drop OL-16597-01 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide 31-11
