# Configure the VLAN operation mode as transparent for UNI 1 and UNI 2.
[Sysname-Onu3/0/1:1] uni 1 vlan-mode transparent
[Sysname-Onu3/0/1:1] uni 2 vlan-mode transparent
For detailed information about ONU uplink bandwidth and VLAN operation mode of a UNI, refer to
EPON-OLT in the Access Volume.
# Configure priority remarking for UNI 1 and UNI 2.
[Sysname-Onu3/0/1:1] uni 1 classification-marking index 1 queue 3 priority 3 src-mac equal
000A-EB7F-AAAB
[Sysname-Onu3/0/1:1] uni 2 classification-marking index 1 queue 1 priority 1 src-mac equal
001B-EB7F-21AC
After the configuration above is complete, when two streams (each 50 Mbps) from two UNIs of the ONU
are being forwarded to the OLT, the packets sourced from the MAC address of 001B-EB7F-21AC are
dropped at forwarding congestion on the ONU port, because the queue precedence of these packets is
lower than that of the packets sourced from the MAC address of 000A-EB7F-AAAB.
