2-621Cisco Catalyst Blade Switch 3120 for HP Command ReferenceOL-12248-03Chapter 2 Cisco Catalyst Blade Switch 3120 for HP Cisco IOS Commandsshow mls qos mapsshow mls qos mapsUse the show mls qos maps user EXEC command to display quality of service (QoS) mappinginformation. During classification, QoS uses the mapping tables to represent the priority of the trafficand to derive a corresponding class of service (CoS) or Differentiated Services Code Point (DSCP) valuefrom the received CoS, DSCP, or IP precedence value.show mls qos maps [cos-dscp | cos-input-q | cos-output-q | dscp-cos | dscp-input-q |dscp-mutation dscp-mutation-name | dscp-output-q | ip-prec-dscp | policed-dscp] [ | {begin| exclude | include} expression]Syntax DescriptionCommand Modes User EXECCommand HistoryUsage Guidelines Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain outputdo not appear, but the lines that contain Output appear.The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digitin the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or themutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoSvalue of 5.cos-dscp (Optional) Display class of service (CoS)-to-DSCP map.cos-input-q (Optional) Display the CoS input queue threshold map.cos-output-q (Optional) Display the CoS output queue threshold map.dscp-cos (Optional) Display DSCP-to-CoS map.dscp-input-q (Optional) Display the DSCP input queue threshold map.dscp-mutation dscp-mutation-name (Optional) Display the specified DSCP-to-DSCP-mutationmap.dscp-output-q (Optional) Display the DSCP output queue threshold map.ip-prec-dscp (Optional) Display the IP-precedence-to-DSCP map.policed-dscp (Optional) Display the policed-DSCP map.| begin (Optional) Display begins with the line that matches theexpression.| exclude (Optional) Display excludes lines that match the expression.| include (Optional) Display includes lines that match the specifiedexpression.expression Expression in the output to use as a reference point.Release Modification12.2(40)EX1 This command was introduced.
