TUN interface[uesimtun0, 60.61.0.1] #369

Open noormohammedli opened 3 years ago

noormohammedli commented 3 years ago

Hello Sir,

I installed the free5GC Stage 3 Installation Guide from this link " https://www.free5gc.org/installations/stage-3/" by fallow this link "https://www.free5gc.org/stage-3-videos/create-ubuntu-machine/" and the UERANSIM from " https://github.com/aligungr/UERANSIM/wiki/Installation". At the beginning, everything went fine, I installed the 5G core and UERANSIM as well in different VMs.

In the UERANSIM VM, the UE is connected to the RAN and RAN connect to the free5GC VM. but the UE lost connection, as I see I had a connection failure. Also, TUN interface[uesimtun0, 60.61.0.1] not created.

Hello @noormohammedli

It seems that there are lots of "address already in use" errors. Please make sure that there is no other program using the same ports. (Perhaps you run more than one gNodeBs?)

(If you are unable to figure it out, try restarting your virtual machines)

Regards

Hello, Yes, I restart the VM and try it again they are connected but the tun interface is still not created.

Thanks. That's strange. "Initial random id conflict" is a very unusual error, and it may be a temporary situation. Is this issue still exists?

noormohammedli commented 3 years ago

Yes, Still exists.

uesimtun0 interface is not created. I am having the same problem. I used 3 different VMs to setup UERANSIM with free5gc. 1 machine running only UE. 2nd machine running gNB. I see successful connection between two machines. (UE and gNB are connected). 3rd. free5gc is configured. I can see a session established at SMF and UPF when I try to connect UE. After every connection and restarting a couple of times, still there is no uesimtun0 interface at UE VM.

@shahid2636 Please share your UE, gNodeB and core network logs.

shahid2636 commented 3 years ago

image image image image I am using a custom build UPF with ONOS. My UPF accepts PFCP request and responds to SMF which can be confirmed by SMF logs.

aligungr commented 3 years ago

@shahid2636

Looks like the issue is related to core network according to the logs you share.

It would be better to open a issue in free5gc side.

Regards.
