Follow these steps to configure the mapping between CoS precedence values and local precedence 

values: 

Enter system view 

— 

Enter ONU port view 

interface interface-type 
interface-number 

— 

Configure the mapping 
between CoS precedence 
values and local 
precedence values 

qos cos-local-precedence-map 
cos0-map-local-prec 
cos1-map-local-prec 
cos2-map-local-prec

Required 

For the default mapping, see

You can classify the traffic received on a UNI based on information in the traffic, such as MAC address 

and IP address, and then configure different mapping policies for each class of packets. When the ONU 

receives packets on a UNI, it determines the actions to perform for packets based on the match criteria, 

VLAN operation mode of the port, and VLAN tagging status of the received packets. For details, refer to 

Table 12-4 Relationship between VLAN operation modes and priority remarking  

With VLAN tag 

z 

In the case of traffic classification based on the source 
MAC address/destination MAC address, Ethernet 
priority, VLAN ID, or physical port, if the packet 
matches the configured traffic classification rule, the 
packet is priority-remarked with the value specified in 
the rule and is then forwarded; otherwise, the packet 
is directly forwarded. 

z 

In the case of traffic classification based on Ethernet 
type, DSCP, IP protocol type, source IP 
address/destination IP address, or source L4 port, the 
packet is forwarded without any change.  

Transparent 
mode 

Without VLAN tag 

The packet is forwarded without any change. 

With VLAN tag 

The packet is dropped. 

Tag mode 

Without VLAN tag 

The packet is tagged with the VLAN tag corresponding to 
the default PVID of the port, and then: 

z 

If the packet matches the configured traffic 
classification rule, the packet is priority-remarked with 
the value specified in the rule and is then forwarded; 

z 

Otherwise, the packet is remarked with the port 
priority and is then forwarded.
