If a UNI of an ET254-L ONU is added to an isolation group, the operation mode of the UNI port can 

be set to the transparent transmission mode only, but not VLAN tag mode or VLAN translation 

mode.  

 

If all ONU ports under an OLT port are access ports, to make sure that the packets received on the 

ONU port and PC are untagged packets, the VLAN operation mode of a UNI can only be 

configured as the transparent transmission mode.  

 

# Configure the VLAN operation mode of UNI 1 as VLAN tag mode, add the VLAN 100 tag to the 

untagged packets received on the port, and set the 802.1p precedence of the packets to 3.

uni-number: UNI number, in the range 1 to the number of UNI ports of the current ONU. The number of 

UNIs can be up to 80.  

priority-value: 802.1p precedence for packets, in the range 0 to 7. 

pvid: VLAN ID, in the range 1 to 4094.  

oldvid: Original VLAN ID, in the range 1 to 4094.  

newvid: New VLAN ID, in the range 1 to 4094.  

&<1-15>: Means that you can specify up to 15 VLAN IDs for the corresponding argument.  

Use the uni vlan-mode translation pvid command to configure the VLAN operation mode of the 

specified UNI as the VLAN translation mode and set the related parameters.  

Use the undo uni vlan-mode command to restore the default VLAN operation mode of the UNI.  

By default, the VLAN operation mode of a UNI is VLAN transparent transmission mode.  

Related commands: uni vlan-mode tag pvid, uni vlan-mode transparent.
