 qos dscp enable 

The  qos dscp config command is used to configure the mapping relation 

between DSCP Priority and 802.1P Priority. To return to the default configuration, 

please use no qos dscp config 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. 

{dscp-list} {cos-id} 

 

  ——  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. 

  ——  The priority level the packets with tag are mapped to, which ranges 

from CoS 0 to CoS 7. 

Global Configuration Mode

 

DSCP priorities are mapped to the corresponding 802.1p priorities. IP datagram 

will detemin its egress queue based on the mapping relation between 802.1p 

priority and priority levels. 

Map DSCP values 10,11,15 to CoS0:
