DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide The DSCP to CoS map is used by a DSCP trust port to map a DSCP value to an internal CoS value. In turn this CoS value is then mapped to the CoS queue based on the CoS to queue map configured by the priority-queue cos-map command. Example This example shows how to configure the DSCP to CoS map for mapping DSCP 12, 16, and 18 to CoS 1 for eth2/0/6. Switch# configure terminal Switch(config)# interface eth2/0/6 Switch(config-if)# mls qos map dscp-cos 12,16,18 to 1 Switch(config-if)# 54-10 mls qos map dscp-mutation This command is used to define a named Differentiated Services Code Point (DSCP) mutation map. To remove the mutation map, use the no form of this command. mls qos map dscp-mutation MAP-NAME INPUT-DSCP-LIST to OUTPUT-DSCP no mls qos map dscp-mutation MAP-NAME Parameters MAP-NAME INPUT-DSCP-LIST OUTPUT-DSCP Specifies the name of the DSCP mutation map in a string length up to 32 characters (no space is allowed) Specifies the list of DSCP code point to be mutated to another DSCP value. The range is from 0 to 63. A series of DSCPs can be separated by commas (,) or hyphens (-). No space or hyphen is before and after. Specifies the mutated DSCP value. Valid values are from 0 to 63. Default The output DSCP is equal to the input DSCP. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline When a packet is received by an interface, based on a DSCP mutation map, the incoming DSCP can be mutated to another DSCP immediately before any QoS operations. The DSCP mutation is helpful to integrate domains with different DSCP assignments. When configuring a named DSCP mutation map, note the following: • Enter multiple commands to map additional DSCP values to a mutated DSCP value. • Enter a separate command for each mutated DSCP value. The DSCP-CoS map and DSCP-color map will still be based on the packet's original DSCP. All the subsequent operations will base on the mutated DSCP. Example 484
