"Operation Status: Failed" ONT

Hi User,

An ONU connected to a GPON port of an OLT can go online successfully, but the queried Config state of the ONU is displayed as failed by running the display ont info command on the OLT and the ONU cannot work properly.

To better understand this fault, let's see the meaning of the ONU configuration status.

The ONU configuration status indicates whether the configuration restoration is enabled and whether the configuration restoration is complete. Configuration recovery refers to a process in which, after an ONU goes online, the OLT issues configurations to the ONU and then the ONU adjusts its operating parameters based on the issued configurations.
The ONU configuration status has the following states: initial, normal, configuring (config), and configuration failure (failed). When an ONU goes online, the ONU is in the configuration restoration stage. 

• The first status is initial. Soon the initial is complete and the ONU enters the config state. 
  

• In the config state, the ONU capability and configuration data are restored. The duration of the config state is determined by the amount of the data configured on the ONU. 
  

• If the configuration restoration is successful, the ONU transitions from the config state to the normal state.

• If the configuration restoration fails, the ONU transits from the config state to the failed state. Then the service is probably not carried forward.

After understanding the configuration status, let's see how to locate a problem.

thanks in advance

Hi @sohaib.ansar thanks for the suggestion.
In my case I am failing to understand the capability mismatches based on the diagnose command I posted above.
I don't understand what I am sending wrong and how I can fix or restore the config correctly?

Dear dishma237,

With regard to the problem you described, after I looked at your configuration interface, I thought it was beyond ont's capabilities.

It is recommended that you change the GEM port ID to a smaller value ranging from 1 to 32.

The information you give below the post is of little use because the otn is offline.

I hope it will help you. Thank you!
