DOWNLINK isn't working in SRSRAN-magma 5G setup #1110

Open mounika-alavala opened 1 year ago

mounika-alavala commented 1 year ago

Hi We setup Magma AGW and orchestrator on Openstack VMs. We also setup SRSRAN on another openstack VM. We have used srsRAN and UERANSIM with MAGMA Core setup. srsRAN is able to integrate with magma. We are able to ping UE from AGW and vice versa. With SRSRAN, using iperf UPLINK is working but not DOWNLINK. UERANSIM is not getting attached, there is some problem with AMF Auth key(even after using hexadecimal).

Attached are the screenshots of the same. Ping works: image image Also, using iperf3, I am able to run traffic from the UE to agw (uplink) and see the trace on srsenb console. image image image But am not able to run traffic from agw to UE. image image image No firewall is running. image image

Can someone suggest a possible solution? Thanks in advance.

If ping works, both UL and DL is working. If your iperf3 DL session isn't working maybe verify the listening IPs etc. Maybe also try iperf and use UDP to confirm the traffic is flowing there.

UE is attached successfully and assigned IP - 192.168.128.21. iperf server is listening on UE side Screenshot (1615) Ping works from agw to UE Screenshot (1618) But we see no traffic in the iperf DL session: Screenshot (1619) Screenshot (1620) The following screenshots were taken of iperf3 DL sessions: AGW side: Screenshot (1624) UE side: Screenshot (1623) Screenshot (1622)

Any help is appreciated. Thanks!
