Delivery Status

DO NOT EDIT

Only the Integration PTL should edit the delivery status table to track the release validation progress

		Notes
Deployment Artifacts	Docker Container	O-DU-RIC-STUB is not available in OSC Nexus
	Helm Charts
	Deployment scripts
E2E Flows	E2 UE Attach Procedure	The CU stub and RIC stub is also used in the O-DU-high and O-DU-low integrated flow

This page describes running O-DU High using test stubs, namely CU Stub and RIC Stub. O-DU High also uses Phy Stub in the absence of O-DU Low. However, Phy Stub is built as a part of the O-DU High image itself.

Execution of below steps yields successful UE Attach procedure and message exchanges required for Traffic Steering use-case on the E2 interface. These can be verified on wireshark by capturing SCTP packets.

Prepare environment

sudo apt-get install libpcap-dev libsctp-dev

Cloning code

mkdir odu_high
cd odu_high
git clone "https://gerrit.o-ran-sc.org/r/o-du/l2"

Compilation of O-DU

cd odu_high/l2/build/odu
make clean_odu odu MACHINE=BIT64 MODE=FDD

Compilation of CU Stub

cd odu_high/l2/build/odu
make clean_cu cu_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

Compilation of RIC Stub

cd odu_high/l2/build/odu
make clean_ric ric_stub NODE=TEST_STUB MACHINE=BIT64 MODE=FDD

Execution - Assign IP addresses

ifconfig <interface name>:ODU “192.168.130.81”
ifconfig <interface name>:CU_STUB “192.168.130.82”
ifconfig <interface name>:RIC_STUB “192.168.130.80”

Running CU Stub

cd odu_high/l2/bin/cu_stub
sudo ./cu_stub

Running RIC Stub

cd odu_high/l2/bin/ric_stub
sudo ./ric_stub

Running O-DU
```
cd odu_high/l2/bin/odu
sudo ./odu
```
Note:
1. Each of the above binaries must be run in separate terminals
2. CU Stub and RIC Stub images must be run before O-DU image.
