

Indicates the priority determined by the DSCP region of IP 
datagram. It ranges from 0 to 63. 

Indicates the priority level the packets with tag are mapped to. The 
priority levels are labeled as TC0, TC1, TC2 and TC3. 

To complete QoS function configuration, you have to go to the Schedule Mode page to select a 
schedule mode after the configuration is finished on this page. 

Configuration Procedure: 

1  Configure the mapping 

relation between the DSCP 
priority and TC 

Required. On QoS→DiffServ→DSCP Priority page, 
enable DSCP Priority and configure the mapping 
relation between the DSCP priority and TC. 

2 

Select a schedule mode 

Required.  On  QoS→DiffServ→Schedule Mode 
page, select a schedule mode. 

On this page you can configure the mapping relation between the 802.1P priority tag-id/CoS-id and 
the TC-id.   

802.1P gives the Pri field in 802.1Q tag a recommended definition. This field, ranging from 0-7, is 
used to divide packets into 8 priorities. 802.1P Priority is enabled by default, so the packets with 
802.1Q tag are mapped to different priority levels based on 802.1P priority mode but the untagged 
packets are mapped based on port priority mode. With the same value, the 802.1P priority tag and 
the CoS will be mapped to the same TC. 

Choose the menu QoS→DiffServ→802.1P/CoS Mapping to load the following page.
