tc-id
—— The egress queue the packets with tag are mapped to. It ranges from
0 to 7, which represents TC queue from TC0 to TC7 respectively.
Command Mode
Global Configuration Mode
User Guidelines
1. By default, the mapping relation between tag/cos and the egress queue is:
0-TC2, 1-TC0, 2-TC1, 3-TC3, 4-TC4, 5-TC5, 6-TC6, 7-TC7.
2. Among the priority levels TC0-TC7, the bigger value, the higher
priority.
Example
Map CoS 5 to TC 2.:
T2700G-28TQ(config)#qos queue cos-map
5 2
qos queue dscp-map
Description
The
qos queue dscp-map
command is used to configure the mapping relation
between DSCP Priority and the TC egress queue. 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

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-pri
—— The cos priority the packets with tag are mapped to. It ranges from
0 to 7, which represents CoS0 to CoS7 respectively.
