The configuration does not work after restarting olt. #16

Closed Bai-genew closed 2 years ago

Bai-genew commented 2 years ago

Dear @selvaitech, After the configuration file 2_grpc-settings_1.0.xml is issued, port 8433 is established. However, after restarting olt, port 8433 will disappear. The configuration file 2_grpc-settings_1.0.xml or configuration file force-align.xml was issued, but port 8433 still did not appear.

It looks like a known problem. Lets call it "a feature". OB-BAA sends an empty copy-config to the OLT immediately after "device create" request. This copy config kills all the existing OLT configuration, including ietf-netconf-server. In result, netopeer2-server stops listening for new incoming connections. If OLT device is destroyed in OB-BAA and then re-created, it doesn't work because OLT is not accepting connections. I was told that it is possible to setup OB-BAA so that it will send some initial configuration in the copy-config request. That should allow to re-instate ietf-netconf-server configuration so that it keeps listening on the port 8433. I don't know how to do it, re-assigning this ticket to the OB-BAA team

@Bai-genew, can you use the tag push-pma-configuration-to-device set to "false" and try the steps? If this flag is set to false, OB-BAA will not be sending the initial config(copy-config) towards the device so that the device configurations are not erased.
