If a UNI port 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 mode.  

 

# Configure the VLAN operation mode of UNI 1 as VLAN transparent transmission mode.

minimum-bandwidth value1: Specifies the minimum uplink bandwidth, in the unit of 64 kbps. value1 is 

in the range 8 to 14400 and defaults to 32.  

maximum-bandwidth value2: Specifies the maximum uplink bandwidth, in the unit of 64 kbps. value2 

is in the range 8 to 16000 and defaults to 368.  

delay: Specifies the delay mode. The low keyword means that low delay is adopted and the high 

keyword is high delay. Low delay is adopted by default. 

Use the upstream-sla  command to set the ONU's minimum uplink bandwidth, maximum uplink 

bandwidth, and delay mode of packet forwarding through the EPON system.  

Use the undo upstream-sla command to restore the default values.
