Chapter 2.2 Switch setup
Chapter 2.2.1 Dell Switch
In the following example the RUs are on ports 1 and 7, the GrandMaster is on port 5, the CN is on ports 11 and 12, and the gNB ports are connected to ports 49 and 51 all on vlan 2.
Set up MGMT access to the switch
Enable PTP on the switch:
OS10# configure terminal
OS10(config)#
ptp clock boundary profile g8275.1
ptp domain 24
ptp system-time enable
!
Configure the GrandMaster port:
OS10(config)# interface ethernet 1/1/5:1
no shutdown
no switchport
ip address 169.254.2.1/24
flowcontrol receive off
ptp delay-req-min-interval -4
ptp enable
ptp sync-interval -4
ptp transport layer2
!
Configure the other ports (repeat as necessary):
OS10(config)# interface ethernet1/1/1:1
no shutdown
switchport mode trunk
switchport trunk allowed vlan 2
mtu 8192
flowcontrol receive off
ptp enable
ptp transport layer2
!
Check the PTP status:

Chapter 2.2.2 Fibrolan Falcon RX Setup
Although the Fibrolan switch has not be qualified in NVIDIA lab, OAI labs incorporate the following configuration and switch for interoperability
To get started follow the Fibrolan Getting Started Guide.
In our setup the Qulsar GrandMaster is connected to port 4, the Aerial SDK to port 17, and the Foxconn RU to port 16 (C/U plane) and port 15 (S/M plane). You can ignore all other ports in the figures[A][B] below.
VLAN setup
In the following we assume that the VLAN tag for both the control plane and the user plane of the O-RAN CU plane is 2. VLAN 80 is used for everything else.
Open the configuration page of the Fibrolan switch, go to configuration -> VLANs. Port 4 (the Qulsar GrandMaster) needs to be configured in Access mode using and setting the port VLAN to 80.
Use the same configuration for port 15 (RU S/M plane).
Ports 16 and 17 need to be configured in Trunk mode, port VLAN 80, Untag Port VLAN, Allowed VLANs 80,2
DHCP setup
The RU M-plane requires to setup a DHCP server. Go to Configuration -> DHCP -> server -> pool and create a new DHCP server with the following settings
PTP setup
For the PTP setup, first follow the Fibrolan “PTP Boundary Clock Configuration” guide with the following specific settings: • Device Type “Ord-Bound” • Profile “G8275.1” • Clock domain 24 • VLAN 80 Also make sure you enable the used ports (4,15,16,17 in our case)
We also recommend to use “hybrid mode” as sync mode.
If everything is configured correctly, the Sync Center should be green
Chapter 2.3 PTP Setup
Step 1.
Enter these commands to configure PTP4L assuming the ens6f0
NIC interface and CPU core 20 are used for PTP:

Update network config on DU (aerial-ae-devkit-01):
Check the 10G interface connection of DU over the switch
To figure out what is actually connected, go into switch and run below, and then correlate the network device name on aerial-ae-devkit-01 with that MAC address on port 1/1/49. Answer ens6f0
OS10# show mac address-table
Codes: pv <vlan-id> - private vlan where the mac is originally learnt
VlanId Mac Address Type Interface

2 6c:ad:ad:00:02:02 dynamic ethernet1/1/1:1
2 b8:ce:f6:95:5f:6c dynamic ethernet1/1/49
Steup the DU 10G interface
At this point, we need to teardown the 1G interface and config the 10G interface on DU:
Note: Add these instructions to system startup script ‘/etc/rc.local’ so that we don’t have to manually run them when there is a reboot
| sudo ip link add link ens6f0 name ens6f0.2 type vlan id 2
| sudo ip addr add 169.254.1.101/24 dev ens6f0.2
| sudo ip link set up ens6f0.2
Check the 10G M-Plane connection
Ping with the 10G interface to O-RU from DU should be working by now:
| aerial@aerial-ae-devkit-01:~$ ping 169.254.1.11

This section describes how to setup the Aerial private 5G network which consists of:
Aerial SDK L1
Remaining components of OAI gNB
OAI Core Network
User Equipment (UE)
Edge Server Applications(e.g. iPerf)
These instructions assume that the core network and gNB can be deployed on the same host server.
Software Release Manifest
Component | Version |
Aerial SDK (ASDK) PHY | 22.2.2 |
OAI gNB | 2022.w50 |
OAI CN | 1.4.0 |
Setup Aerial SDK L1
Please follow the step by step installation guide for cuBB located at NVIDIA Developer Zone - Aerial SDK https://developer.nvidia.com/docs/gputelecom/aerial-sdk/text/cubb_install/index.html
cuBB Installation Guide: From System Requirements to Troubleshooting**()
Since cuBB 22.2.2 release, the test vectors are not included in the SDK. The developer needs to generate the TV files first before running cuPHY examples or cuBB end-to-end test.
Using Aerial Python mcore Module
No Matlab license required to generate TV files using Aerial Python mcore module. The cuBB Container already has aerial_mcore installed. To generate the TV files, run the following commands inside the Aerial container.
The TV generation may take few hours on the devkit with current isocpus parameter setting in kernel command line. Please also ensure the host has sufficient space to contain 111GB of TV files.
cd ${cuBB_SDK}/5GModel/aerial_mcore/examples
source ../scripts/setup.sh
export REGRESSION_MODE=1
time python3 ./example_5GModel_regression.py allChannels
echo $?
ls -alF GPU_test_input/
du -h GPU_test_input/
Example output is shown below. The “real” time takes less than one hour on a 24 cores x86 host. The “echo $?” shows the exit code of the process, which should be 0. A non-zero exit code indicates a failure.

To Generate the launch pattern for each test case using cubb_scripts:
cd $cuBB_SDK
cd cubb_scripts
python3 auto_lp.py -i ../5GModel/aerial_mcore/examples/GPU_test_input -t launch_pattern_nrSim.yaml
Then Copy the launch pattern and TV files to testVectors repo.
cd $cuBB_SDK
cp ./5GModel/aerial_mcore/examples/GPU_test_input/TVnr_* ./testVectors/.
cp ./5GModel/aerial_mcore/examples/GPU_test_input/launch_pattern* ./testVectors/multi-cell/.
Using Matlab
To generate TV files using Matlab, run the following command in Matlab:
cd('nr_matlab'); startup; [nTC, errCnt] = runRegression({'TestVector'}, {'allChannels'}, 'compact', [0, 1] );
All the cuPHY TVs are generated and stored under nr_matlab/GPU_test_input
.
Generate the launch pattern for each test case using cubb_scripts:
cd $cuBB_SDK
cd cubb_scripts
python3 auto_lp.py -i ../5GModel/nr_matlab/GPU_test_input -t launch_pattern_nrSim.yaml
Copy the launch pattern and TV files to testVectors repo.
cd $cuBB_SDK
cp ./5GModel/nr_matlab/GPU_test_input/TVnr_* ./testVectors/.
cp ./5GModel/nr_matlab/GPU_test_input/launch_pattern* ./testVectors/multi-cell/.
PTP slave setup Please refer to installation instructions at Installing Tools — Aerial SDK 22-2.2 documentation (nvidia.com)
Setup OAI gNB
Install Ubuntu on both servers
https://releases.ubuntu.com/20.04.4/ubuntu-20.04.4-desktop-amd64.iso
Run the following:
sudo apt update sudo apt dist-upgrade sudo apt autoremove
Prepare gNB docker images
Build gNB docker image
Check out the OpenAirInterface5G repository
git clone https://gitlab.eurecom.fr/rssilva/openairinterface5g.git
cd openairinterface5g
git checkout FAPI-Improvements
Build the docker image
docker build . -f docker/Dockerfile.aerial.ubuntu20
gNB configuration file
vnf.sa.band78.fr1.273PRB.Aerial.conf
What parameters need to be changed by the user?
TBD - docker-compose yaml file and an entrypoint script for the docker container(targeted in next release)
Setup OAI CN5G
Do this iptables setup below every time after a system reboot. It is also possible to make this permanent in Ubuntu system configuration.
On CN5G server, configure it to allow the traffic coming in by
adding this rule to iptables:
# On CN5G, upon startup:
sudo sysctl net.ipv4.conf.all.forwarding=1
sudo iptables -P FORWARD ACCEPT
Install the core network by following these steps:
The user configurable configuration files are:
~/oai-cn5g-fed/docker-compose/docker-compose-basic-nrf.yaml
~/oai-cn5g-fed/docker-compose/database/oai_db.sql
Configuring OAI gNB and CN5G
For the purpose of understanding which address is what in the example configuration setting and commands below, we will assume the gNB and CN5G servers have these interface names and IP addresses.
CN5G Server
eno1: 10.31.66.x = SSH management port for terminal
eno2: 169.254.200.6 = BH connection on SFP switch for gNB-CN5G traffic
gNB Server
eno1: 10.31.66.x = SSH management port for terminal
ens6f0: b8:ce:f6:4e:75:40 = FH MAC address
ens6f0.2: 169.254.1.105 = FH IP address
ens6f1: 169.254.200.5 = BH connection SFP switch for gNB-CN5G traffic
gNB to set static route
On the gNB server, add this static route for a path to the CN5G server. Please apply this route each time after the server power-on.
Syntax:
sudo ip route add 192.168.70.128/26 via <CN5G IP> dev <gNB interface for CN5G>
Example:
sudo ip route add 192.168.70.128/26 via 169.254.200.6 dev ens6f1
gNB to set the CN5G server to uses for AMF
Edit gNB configuration file: targets/PROJECTS/GENERIC-NR-5GC/CONF/vnf.sa.band78.fr1.273PRB.Aerial.conf
Below is an example with lab-specific network parameters. Your IP address and interface names may differ.
GNB_INTERFACE_NAME_FOR_NG_AMF = "ens6f1"; # gNB side interface name of the SFP port toward CN (was eno1)

Running CN5G
To start CN5G
cd ~/oai-cn5g-fed/docker-compose
python3 core-network.py --type start-basic --scenario 1
Or alternatively:
docker-compose up -d
To Stop CN5G
cd ~/oai-cn5g-fed/docker-compose
python3 core-network.py --type stop-basic --scenario 1
Or alternatively:
docker-compose down
To monitor CN5G logs while running
docker logs oai-amf -f
To capture PCAPs
docker exec -it oai-amf /bin/bash
apt update && apt install tcpdump -y
tcpdump -i any -w /tmp/amf.pcap
Then we can copy the pcap out from the container
docker cp oai-amf:/tmp/amf.pcap .

Step 1: Add the SIM User Profile
Modify:
oai_db.sql (with plain text editor)
There are currently 3 UEs pre-configured here, just search for: 001010000000001 and you will find them, add/edit as needed.
docker-compose-basic-nrf.yaml
MCC, MNC, OPERATOR_KEY (you need to change them in several places)
On gNB server, change the MCC and MNC in the gNB config file ./targets/PROJECTS/GENERIC-NR-5GC/CONF/vnf.sa.band78.fr1.273PRB.Aerial.conf
plmn_list = ({
- mcc = 208;
- mnc = 98;
+ mcc = 001;
+ mnc = 01;
mnc_length = 2;
Step 2: Setup the UE and SIM Card
For reference, please use the following
*SIM cards – 4G and 5G reference software (open-cells.com)*
Program SIM Card with Open Cells Project application “uicc-v2.6” https://open-cells.com/d5138782a8739209ec5760865b1e53b0/uicc-v2.6.tgz
Use the ADM code specific to the SIM card. If wrong ADM is used for 8 times, the SIM card will be permanently locked.
sudo ./program_uicc --adm 12345678 --imsi 001010000000001 --isdn 00000001 --acc 0001 --key fec86ba6eb707ed08905757b1bb44b8f --opc C42449363BBAD02B66D16BC975D77CC1 -spn "OpenAirInterface" --authenticate

Succeeded to authentify with SQN: 64
set HSS SQN value as: 96
CUE Configuration Setup
Install the “Magic IPERF” application on the UE:
To test with CUE, a test SIM card with Milenage support is required. The following has to be provisioned on the SIM and it has to match the Core Network settings: mcc, mnc, IMSI, Ki, OPc
The APN on the CUE should be configured according to Core Network settings.
Start the DNS (Core network should assign mobile IP address and DNS. If DNS is not assigned, set DNS with other Android app.)
Step 3. Running End-to-End OTA
This section describes how to run end to end traffic from UE to the edge core network.
Start OAI CN5G Core Network
Start CN5G Network
sudo sysctl net.ipv4.conf.all.forwarding=1
sudo iptables -P FORWARD ACCEPT
cd ~/oai-cn5g-fed/docker-compose
python3 core-network.py --type start-basic --scenario 1
Start CN5G Edge Application
After the CN5G is started, we can use oai-ext-dn container to run IPERF
docker exec -it oai-ext-dn /bin/bash
Start NVIDIA Aerial cuBB on the gNB
# Run on host: start a docker terminal
docker exec -it cuBB /bin/bash
# Run in docker container
export CUDA_DEVICE_MAX_CONNECTIONS=16
$cuBB_SDK/build/cuPHY-CP/cuphycontroller/examples/cuphycontroller P5G
# Wait until see console log
====> PhyDriver initialized!
16:29:35.913840 C [NVIPC:DEBUG] ipc_debug_open: pcap enabled:
fapi_type=1 fapi_tb_loc=1
16:29:36.141657 C [NVIPC:SHM] shm_ipc_open: forward_enable=0

16:29:36.153816 C [CTL.SCF]
====> cuPHYController initialized, L1 is ready!
Start OAI gNB L2 Stack on the gNB
Start up the OAI container:
docker run -dP --privileged --ipc container:c_aerial_aerial \
--gpus all --network host --shm-size=4096m -it \
-v /lib/modules:/lib/modules \
-v /dev/hugepages:/dev/hugepages \
-v /usr/src:/usr/src \
-v ~/openairinterface5g:/opt/oai/ \
-v ~/share:/opt/nvidia/cuBB/share \
--cpuset-cpus=6-13\
--name i_oai_aerial c_oai_aerial:latest
Then start the OAI nr-softmodem, enter the the container to run the using the configuration file mounted from the host
docker exec -it i_oai_aerial bash
# cd to the openairinterface directory
source oaienv
cd cmake_targets/ran_build/build/
./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/vnf.sa.band78.fr1.273PRB.Aerial.conf --nfapi aerial --sa
To stop the container:
docker stop i_oai_aerial
docker rm i_oai_aerial
CUE Connecting to 5G Network
Take the CUE out of Airplane mode to start the UE attaching to the network.
Observe 5G Connect Status
See Preamble log in cuphycontroller console output.
Check Core Network log or CUE log to see whether NAS authentication and PDU session succeed.
Running E2E IPERF Traffic
Start ping, iperf or other network app tests after PDU session connected successfully.
One can install and run “Magic IPerf” Android application on the CUE for this purpose.
