Hello, friend!
The methods of setting the VLAN priority on the ONU are as follows:
1. For VLANs (such as service VLANs) that are transparently transmitted by the ONU, the VLAN priority is set to the priority configured in the traffic profile referenced by service-port command.
2. For the ONU VLAN (such as the management VLAN), run protocol-8021p-pri command to set the VLAN priority. For the ONU V800R308 and later versions, you can run vlan priority command to set the priority.
3. For the VLAN of the media IP address or signaling IP address in the VoIP service, run qos vlan command to set the VLAN priority.
Thank you!
