There is no PFCP Association Setup Response, is your UPF running successfully?

#15

Kindly ignore the previous wireshark captures on pfcp.There were some warnings in pcf entity when I captures those logs.
After restarting my system I freshly took wireshark captures. I didnot notice any pfcp messages.
Im attaching entire terminal logs and fresh wireshark captures. It doesnot contain any pfcp messages even after applying filters.

I found the error:

http2: server connection error from 10.100.200.9:44714: connection error: PROTOCOL_ERROR

Try to set all of your sbi to https, will it work?

#17

Do you mean scheme has to be changed to https in all the config files?

Yes, for “all” config file. Let’s give it a try.

#19

Errors are coming like this after changing to https

If your scheme of NRF change to https, your nrf url for each NF must also be modify.

  1. I have modified http to https in all the places in config file, but still getting this error.

One more thing is that the same code base works fine without docker environment. In one/two runs we will ge this “cant find UPF with DNN” error, but after multiple runs we will be successful. (with sbi set to http)

#25

How about the latest log and pcap file. Maybe we can try to check it again.

#26

No messages are seen in wireshark as there is error in running entities. Please find the attachment of terminal logs. I dont think changing to https is a good idea.

Any other way of solving this ? Please help us to resolve

#28

can you please provide the latest PCAP file.

The old one still didn’t contain PFCP request. But if the message receive, can’t find UPF with DNN, it will allow SMF always sending the pfcp association request to UPF and get’s the response as well.

#29

As we have changed from http to https in all config files, entities are not running properly and no ngap or pfcp msgs are seen in wireshark. Should I revert it back to http and give you the pcap?
But pfcp association request is not sent to UPF even when the entities are properly up and running. Can you tell me what might be the issue for not having pfcp msgs in the captures?

#30

Can you please tell us what can be done further?

#31

Try to let pfcp message send to UPF successfully.

Trace if the destination of PFCP message same as smfcfg or not, check if your config not set well. And check if UPF receive and response PFCP message.
