DGS-6604 m qos map dscp-mutation qos map dscp-mutation To define a named differentiated services code point (DSCP) mutation map, use the qos map dscp-mutation command in global configuration mode. To return to the default mapping, use the no form of this command. qos map dscp-mutation MAP-NAME INPUT-DSCP-LIST to OUTPUT-DSCP no qos map dscp-mutation MAP-NAME Syntax Description MAP-NAME Name of the DSCP mutation map in a string length up to 32 characters (no space is allowed) INPUT-DSCP-LIST Specifies the list of DSCP code point to be mutated to another DSCP value . The range of DSCP is 0 to 63. A series of DSCPs can be separated by comma (,) or hyphen(-). No space is before and after , or -. OUTPUT-DSCP Mutated DSCP value; valid values are from 0 to 63. Default Command Mode Usage Guideline OUTPUT-DSCP equals the INPUT-DSCP Global configuration When a packet is received by an interface, the incoming DSCP can be mutated to another DSCP right before any QoS operations based on the DSCP mutation map. The DSCP mutation is helpful to integrate domains with different DSCP assignment. When configuring a named DSCP mutation map, note the following: • Multiple commands can be entered to map additional DSCP values to a mutated DSCP value. • A separate command can be entered for each mutated DSCP value. Example Up to 15 ingress-DSCP mutation maps can be configured to mutate the incoming DSCP value before any QoS operation. After the ingress-DSCP mutation map creation, use qos dscp-mutation command to attach the ingress-DSCP mutation map to physical interfaces. The DSCP-CoS map and DSCP-color map will still base on packet's original DSCP. All the subsequent operations will base on mutated DSCP. This example shows how to map DSCP 30 to mutated DSCP value 8, DSCP 20 to mutated DSCP 10, the mutation map named, mutemap1: Switch(config)#qos map dscp-mutation mutemap1 30 to 8 Switch(config)#qos map dscp-mutation mutemap1 20 to 10 Use the show qos map privileged EXEC command to verify the settings.
