16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Configuration Tasks Table 14 shows the default DSCP-to-CoS map. Table 14 Default DSCP-to-CoS Map DSCP values 0 CoS values 0 8, 10 16, 18 24, 26 32, 34 40, 46 48 56 1 2 3 4 5 6 7 If these values are not appropriate for your network, you need to modify them. Beginning in privileged EXEC mode, follow these steps to modify the DSCP-to-CoS map: Step 1 Step 2 Step 3 Step 4 Step 5 Command configure terminal mls qos map dscp-cos dscp-list to cos end show mls qos maps dscp-to-cos copy running-config startup-config Purpose Enters global configuration mode. Modifies the DSCP-to-CoS map. For dscp-list, enter up to 13 DSCP values separated by spaces. Then enter the to keyword. For cos, enter the CoS value to which the DSCP values correspond. The supported DSCP values are 0, 8, 10, 16, 18, 24, 26, 32, 34, 40, 46, 48, and 56. The CoS range is 0 to 7. Returns to privileged EXEC mode. Verifies your entries. (Optional) Saves your entries in the configuration file. To return to the default map, use the no mls qos map dscp-cos global configuration command. Displaying QoS Information To display the current QoS information, use one or more of the privileged EXEC commands in Table 15: Table 15 Commands for Displaying QoS Information Command Purpose show class-map [class-map-name] Displays QoS class maps, which define the match criteria to classify traffic. show policy-map [policy-map-name [class class-name]] Displays QoS policy maps, which define classification criteria for incoming traffic. show mls qos maps [cos-dscp | dscp-cos] Displays QoS mapping information. Maps are used to generate an internal DSCP value, which represents the priority of the traffic. show mls qos interface [interface-id] [policers] show mls masks [qos | security] Displays QoS information at the interface level. Displays details regarding the masks1 used for QoS and security ACLs. 1. Access Control Parameters are called masks in the switch CLI commands and output.
