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 } { tc-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.
tc-id —— The TC queue ID, which ranges from 0 to 3.
Command Mode
Global Configuration Mode
User Guidelines
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.
Example
Map DSCP values 10-12 to TC 2:
TL-SG2452(config)# qos queue dscp-map 10-12 2
For TL-SG2216/TL-SG2424/TL-SG2424P:
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,
