Example Map DSCP values 10-12 to TC 2: T2600G-28TS(config)# qos queue dscp-map 10-12 2 30.7qos queue dscp-map (For other switches) Description The qos queue dscp-map command is used to configure the mapping relation between DSCP Priority and the CoS value. To return to the default configuration, please use no qos queue dscp-map command. DSCP (DiffServ Code Point) is a new definition to IP ToS field given by IEEE. This field is used to divide IP datagram into 64 priorities. When DSCP Priority is enabled, IP datagram are mapped to different priority levels based on DSCP priority mode; non-IP datagram with IEEE 802.1Q tag are mapped to different priority levels based on IEEE 802.1P priority mode if IEEE 802.1P Priority is enabled; the untagged non-IP datagram are mapped based on port priority mode. Syntax qos queue dscp-map { dscp-list } { cos-id } no qos queue dscp-map Parameter dscp-list -- List of DSCP value. One or several DSCP values can be typed using comma to separate. Use a hyphen to designate a range of values, for instance, 1,4-7,11 indicates choosing 1,4,5,6,7,11. The DSCP value ranges from 0 to 63. cos-id -- The priority level the packets with tag are mapped to, which ranges from CoS 0 to CoS 7. Command Mode Global Configuration Mode Privilege Requirement Only Admin, Operator and Power User level users have access to these commands. User Guidelines By default, the mapping relation between DSCP value and the CoS value is: (0-7)-CoS 0, (8-15)-CoS 1, (16-23)-CoS 2, (24-31)-CoS 3, (32-39)-CoS 4, (40-47)-CoS 5, (48-55)-CoS 6, (56-63)-CoS 7. 246
