Configuring Priority Remark
669
Configuration example
# Configure to use the DSCP precedence when a packet enters an output queue
<SW7750> system-view
[SW7750] priority-trust dscp
Configuring the
Mapping Relationship
between 802.1p Priority
Values and Queues
You can modify the mapping relationship between 802.1p priority values and local
precedence values to modify the mapping relationship between 802.1p priority
values and output queues.
Configuration prerequisites
The mapping relationship between 802.1p priority values and local precedence
values and the default mapping table are well known.
Configuration procedure
Configuration example
■
Configure the 802.1p-to-local-precedence as follows: 0 to 2, 1 to 3, 2 to 4, 3
to 1, 4 to 7, 5 to 0, 6 to 5 and 7 to 6.
■
Display the configuration.

Configuring Priority
Remark
Refer to “Priority Remark” on page 660 for the introduction to priority remark.
Priority remark can be implemented in the following ways:
■
Through TP (only non-type-A I/O Modules support this function). When
configuring TP, you can define the action of remarking the DSCP precedence
for the packets exceeding the traffic limit. Refer to “Configuration Procedure
of TP” on page 672.
