Traffic test issue

HI
I am testing currently with oai-5gcn. UE is registered successfully to core network, but I am not able to perform traffic test.
I have used docker container with two different networks for control and data plane as shown below -

Is that okay to use different network interface for data plane as below ?

Container Tester exiting immediately

Hi,
I'm using the docker environment (https://github.com/my5G/my5G-RANTester/wiki/Using-containers). When I run sudo docker-compose up -d the tester container exits immediately. When I try to run a new container, overriding the entrypoint and creating a shell, it doesn't have the uetun. Do you know how to solve this issue?

docker container logs tester:

• time="2021-07-23T10:23:59Z" level=fatal msg="Could not read file in: /workspace/my5G-RANTester/config/config.yml"

I tried editing the tester container's volume in docker-compose.yml this way

volumes:
     - ./config/tester.yaml:/workspace/my5G-RANTester/config/tester.yml

But then I have this error:

[FEATURE REQUEST]: Roaming MCC And MNC

Hi,

Open5gs is in the process of adding roaming support to the 5G core open5gs/open5gs#2194, the implication of this is that the UE will have to use a different MCC/MNC for the UE instead of the one configured for the gNB.

Can you consider adding this feature?

Thanks

PacketRusher: fork of my5G-RANTester

Hi my5G-RANTester Team,

I've wanted to mention that we just released PacketRusher, our fork of my5G-RANTester dedicated to the performance testing of both user plane and control plane. We refactored quite a lot the control plane (and implemented more procedures eg. handover, deregistration, multiple UEs/gNodeB in a single tool..), and we now use the free5gc's gtp5g module of user plane.
We are also in the process of adding integration testing by mocking an AMF.
It's still in the early days, and we are missing documentation and stuff.

We release our code under the Apache 2.0 licence, so we hope our changes will help you, and that we could collaborate!

Thanks a lot for the nice project and cheers,
Valentin

[Question] Maximum number of UEs

Hi
What are the maximum number of UEs are supported or tested with my5G-RANTester ?

Basic test Failed after installation

Add latency test for PDU session establishment

Hi! Thank you for such a great project.
I like the part of latency test that can reflect the core's performance.
Currently it only supports latency testing for UE registration. Do you ever consider adding a new function of testing the latency of PDU session establishment?
I appreciate a lot if you can implement that!

Follow up on multiple UEs registration and other topics

Hello,

Following the guidance you have provided me about increasing the UPF's buffer size, it seems it worked fine to register 100 UEs. My problem was, indeed that I needed to "make UPF" again so many thanks for this, in Free5GC they do not specify this.

Following with this subject, I have been assinged to study Free5GC capabilities, one of them is to study its limits in terms of the number of UEs registrated that it can support. Since it seems that increasing such buffer increases the maximum number of UEs allowed, my question is this: Have you got to any conclusion abouta maximum number of UEs that can be registered? What about the maximum number of UEs to be registered at the same time? I do not know if I will get to a conlcussion if I just keep rising the buffer and the number of UEs to register, both simultaneously and consecutively.

On the other subject I commented in the forum with you, I'm trying to conect the core network to internet, first with a single ping to, for instance, Google DNS (8.8.8.8). I have tried to put such address in the config file but I do not get a response. I guess something is wrog with my network configuration but I cannot find my error. The following script is used in my run.sh for the core network where you can see how I create and delete my network interfaces and iptables . My laptopt local IP address is 102.168.1.60 in the wlp2s0 interface:

sudo ifconfig eno1:amf 10.100.200.3 up
sudo ifconfig eno1:gnbn 10.100.255.39 up
sudo ifconfig eno1:smfp 192.168.2.1 up
sudo ifconfig eno1:upfp 192.168.2.2 up
sudo ifconfig eno1:gnbg 10.200.200.1 up up
sudo ifconfig eno1:upfg 10.200.200.102 up
sudo ifconfig eno1:ue 60.60.0.101 up

sudo sysctl -w net.ipv4.ip_forward=1

sudo iptables -t nat -A POSTROUTING -s 60.60.0.0/24 -j SNAT --to-source 192.168.1.60

sudo systemctl stop ufw

Then I only change amfcfg.config, smfcfg.config and upfcfg.yaml according such interfaces.

amfcfg.config:

configuration:
amfName: AMF
ngapIpList:
- 10.100.200.3

smfcfg.config:

pfcp:
addr: 10.200.200.1

node_id: 10.200.200.101
links:
- A: gNB1
B: UPF
ue_subnet: 60.60.0.0/16

upfcfg.yaml:

pfcp:
- addr: 192.168.2.2

gtpu:
- addr: 10.200.200.102
# [optional] gtpu.name
# - name: upf.5gc.nctu.me
# [optional] gtpu.ifname
# - ifname: gtpif

dnn_list:
- dnn: internet
cidr: 60.60.0.0/24
# [optional] dnn_list[*].natifname
natifname: wlp2s0

With all this setup I have read in the forums I should be able to get a ping to internet, but it doesn't seem to work. I cannot even ping to my gateway 192.168.1.1. Any ideas on this?

Something which I have found these last days is that if I read the traffic with Wireshark passing through these interfaces it does not catch anything, all the traffic seems to go through the loopback interface but I do not understand why since if I do not create such interfaces the core does not start properly. the following shows my ifconfig:

N3 GTP/UDP is not setting

I am having an issue when attempting to ping out via the tunnel interface of the virtual UE. I am using an Open5GS core with multiple physical UE connected and internet access working.

After starting the virtual GNB and UE they attach correctly with the core but the following message "N3 GTP/UDP is not setting" is repeated in the output and pings via the tunnel interface to 8.8.8.8 or google.com fail.

Is there any IP routing required for the tunnel interface to enable internet access?

error trying to start test

i am using open5s with amf, after i update the my5grantester docker-compose.yaml with the correct ip addresses, mnc, mcc, etc ... and try to start the test, i get the below error.

any idea how to troubleshoot this ?

[NGAP] DialSCTPExt not returning

I'm currently trying to setup an Open5GS sandbox for research purposes. I'm new to 5G networks in general and trying to setup my own to better understand 3GPP.

For my Open5GS environment, I've directly used the code from https://github.com/herlesupreeth/docker_open5gs instead for a 5G SA deployment as I've had problems to get my5G's version to work (still trying to debug it).

The docker containers I currently have on my host are the following:

Adding my own logging around DialSCTPExt (before and after), and running the gNB, I get the following:

For the AMF, the port is forwarded (:::38412->38412/sctp), but nothing is for the Control Interface Port.
Now I am stuck trying to understand what is supposed to listen on port 9487.

How do I access UE s command line interface to test its connectivity and use the established PDU session?

Hi ,
I am new to this field. So, these questions may sound too basic to you.
I am able to run./app ue and a pdu session is getting established successfully.
Hpw do i test this pdu session, for example can I login to UE's CLI and ping a website. Can I download some thing using wget from the internet via free5gc network.

Thank you

4G RAN Tester

Many thanks for the awesome software, it helped me a lot to simulate 1000 UEs on Open5GS CN.

Are there any plans to extend this tester to 4G/LTE as well ?

If not, are you aware of similar open-source software tester for 4G/LTE ?

Issue connecting more than 255 UEs

Hi, I'm trying to connect many UEs using the load-test.

The free5GC v3.0.6 stops the Data Plane connection after about 10 devices.
The Open5GS v2.3.6 can connect exactly 255 UEs with the data plane before stops registering new devices.

I tried to update the free5GC to v3.2.1 (the latest stable version - I'm using this repository) and, after running the load-test with 1000 devices, it stopped connecting exactly after 255 successful connections, the same behavior as the Open5GS core.
Btw, the latest version of the free5GC WebUI allows us to insert a lot of IMSI at the same time.

Taking a look at the context.go file, I saw that you are using a uint8 variable to store the device ID on lines 34 and 50. Is it possible that this uint8 id could cause this weird behavior?

Also, I noticed that after near to 400 UEs, the tester crashes with a Broken pipe error in both cores.

Thanks :)

Multiple QoS flows

Hi! I would like to know if my5G-RANTester is able to handle multiple QoS flows in a single PDU session. Thanks in advance.

Show error msg when config file is not found.

Show error msg when config file is not found. Currently, the app shows nothing.

How do I close the PDU session an ddetach the attached ue from the core

Hi there,
I am able to run ./app eu command and the ue is getting attached to the free5gc core that I am running. After the test how do i detach the ue from the network?

Thanks,
Manoj

visualize an interface in your host with name "uetun1"

Hello sir,
Thank you for sharing the code.

I try to connect the code that you share my5G-core as in the picture below with my5G-RANTester to connect the UE and RAN with 5G Core.

How can I know my registration done successfully?
How can I visualize an interface with the name "uetun1"?

Also, I tried your code for the docker (my5G-RANTester-docker), I don't know how can I view the interfaces with the prefix "uetun" inside the Tester container. or create a virtual interface.

Actually, with my5G-RANTester-docker code, it's run for the first time than the next day when I run the code the Tester container turn down and the other container on.
I tried to make it up by using "docker start tester" and service docker restart.

Regards,
