Configuring QoS at the ONU Side
Priority mapping on the ONU port
When the ONU receives packets on an ONU port, it assigns local precedence to the packets according
to the 802.1p-to-local precedence mapping table.
Table 13-3 shows the default 802.1p-to-local
precedence mapping table.

Priority mapping on the UNI
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
