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 egress queue the packets with tag are mapped to. It ranges from
0 to 3, which represents TC0, TC1, TC2, TC3 respectively.
Command Mode
Global Configuration Mode
User Guidelines
1. By default, the mapping relation between tag and the egress queue is:
(0-15)-TC0, (16-31)-TC1, (32-47)-TC2, (48-63)-TC3
2. Among the priority levels TC0-TC3, the bigger value, the higher
priority.
Example
Map DSCP values 10-12 to TC 2:
TL-SL3428(config)#qos queue dscp-map 10-12 2
qos queue mode
Description
The qos queue mode command is used to configure the Schedule Mode. To
return to the default configuration, please use no qos queue mode command.
When the network is congested, the program that many packets complete for
resources must be solved, usually in the way of queue scheduling. The switch
will control the forwarding sequence of the packets according to the priority
