Map 802.1Q tag 5 to TC 2.: 

TL-SG2008(config)# qos queue cos-map 5 2 

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. 

qos queue dscp-map { dscp-list } { tc-id } 

no qos queue dscp-map 

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. 

tc-id —— The TC queue ID, which ranges from 0 to 3. 

Global Configuration Mode

 

By default, the mapping relation between DSCP value and the egress queue is: 

(0-15)-TC 0, (16-31)-TC 1, (3247)-TC 2, (48-63)-TC 3. 

Map DSCP values 10-12 to TC 2: 

TL-SG2008(config)# qos queue dscp-map 10-12 2
