[ERRO][AMF][GMM][AMF_UE_NGAP_ID:1][SUPI:imsi-208930000000003] Select SMF failed: DNN[internet] is not supported or not subscribed in the slice[Snssai: {Sst:1 Sd:010203}]

Hello,

Please share your smfcfg.yaml file, this is most probably related to the SMF configuration file issue due to which this DNN is not subscribed with NRF and hence this error.

Regards,

Could you please remove the below data for other snssai and check this issue again.

  • sNssai: # S-NSSAI (Single Network Slice Selection Assistance Information)
    sst: 1 # Slice/Service Type (uinteger, range: 0~255)

Hi @virendra,
You can run the free5GC installation guide which is a newer version on the official website. It has been tested.
I believe your problem stems from that you cloned a older version of free5GC and UERANSIM.
If you have any further questions, please feel free to ask.

Daniel,

#8

so should I remove everything and install again ?

#9

Yes, please create another virtual machine for it.

#10

Hi, @danielh1204
I am going to install again as you said so currently i am using ubuntu live server as machine in vmbox so should i continue using that or should i use something else

because in that i am unable to access files directly to copy or download file. and also unable to use other software for packet capturing

#11

  1. You can use putty to ssh to your vm to do copy paste.

    Type your vm’s host-only-adaptor IP address at the host name and click Open.

  2. Do you mean downloading files from the vm to your host or, from the internet to the vm?

  3. What other software are you refering to for packet capturing?

#12

2 ) I meant downloading file from vm to local system to share someone if needed.

  1. i was trying to use wireshark
#13
  1. I believe you can set up shared folders in VM with virtualbox manager even in cli, but I haven’t personally tested yet. However, I think the easiest way is just to create a git repo.
  2. Wireshark provides a tool called tshark for cli. It provides similar functions as wireshark. You can refer to their offcial documentations for details.
  3. I will test if there are ubuntu desktop versions that are compatible with free5GC. I will get back to you asap.
#14

Thanks for the help. Do you have any link where i can find how to do using git repo.

#15

You can refer to this website.

This shows how to create a repository and upload files to it with cli.
After that, you can download it to your local system.

#16

Thanks a lot.It will be really helpfull

#17

Hi,
please type the following commands on free5gc vm

$ cd ~/free5gc/NFs/upf
$ go mod tidy

$ ./run.sh

After this, please restart gnb and UE.
