[[Include(WikiToC)]] == ORAN Split 7.2 E2E == === Description === This tutorial contains instructions for setting up 5G ORAN Split 7.2 network using OAI/srsRAN + various O-RUs(LiteOn, Jabil, Benetel) in COSMOS SB1. === Prerequisites === In order to access the test bed, create a reservation and have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS [wiki:GettingStarted getting started] page to get started. === Resources required === 1 server in [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1 COSMOS SB1] domain and sdr1-in3(with SIMCOMM modem) === Tutorial Setup === Follow the steps below to gain access to the [wiki:/Architecture/Domains/cosmos_sb1 sandbox 1 console] and set up nodes with appropriate images. 1. If you don't have one already, sign up for a [https://www.cosmos-lab.org/portal-2/ COSMOS account] 1. [wiki:/GettingStarted#MakeaReservation Create a resource reservation] on sandbox 1 1. [wiki:/GettingStarted#LogintoyourReservation Login] into sandbox 1 console (console.sb1.cosmos-lab.org) with two SSH sessions. 1. Make sure all the resources in the domain are turned off: {{{#!shell omf tell -a offh -t system:topo:allres }}} For this tutorial we will be using the SB1 servers, srv1-lg1, srv2-lg1, USRP N310s in large and medium nodes, sdr1-s1-lg1 and sdr1-md1. 1. Load 5G-tutorial-cosmos.ndz on srv1-lg1,srv2-lg1. {{{#!shell omf load -i 5G-tutorial-cosmos.ndz -t srv1-lg1 }}} 1. Turn all the required resources on and check the status {{{#!shell omf tell -a on -t srv1-lg1,sdr1-in3 }}} {{{#!shell omf stat -t system:topo:allres }}} 1. ssh to the servers, use option -Y for using GUI. {{{#!shell ssh root@srv1-lg1 }}} === Tutorial Execution === [[CollapsibleStart(Initialize DPDK)]] {{{#!shell root@srv1-lg1:~# ./init_dpdk.sh --- Disable CPU sleep state --- WARNING: cpupower not found for kernel 5.15.0-1071 You may need to install the following packages for this specific kernel: linux-tools-5.15.0-1071-realtime linux-cloud-tools-5.15.0-1071-realtime You may also want to install one of the following packages to keep up to date: linux-tools-realtime linux-cloud-tools-realtime --- Set interface enp134s0f0 ring buffer size to 4096 --- ----- Set RX buffer size ----- ----- Set TX buffer size ----- --- Set interface enp134s0f0 MTU to 9000 --- --- Create VFs (enp134s0f0, MTU: 9000, VLAN: 4) --- ----- Creating VF 1 ----- ----- Creating VF 2 ----- --- Unbind/rebind DPDK devices (86:01.0 86:01.1) --- ----- Unbinding VF 0 ----- ----- Unbinding VF 1 ----- ----- Binding VF 0 ----- ----- Binding VF 1 ----- --- Final VF setup --- 3: enp134s0f0: mtu 9000 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 50:7c:6f:6c:76:9c brd ff:ff:ff:ff:ff:ff vf 0 link/ether 00:11:22:33:44:66 brd ff:ff:ff:ff:ff:ff, vlan 4, spoof checking off, link-state auto, trust off vf 1 link/ether 00:11:22:33:44:67 brd ff:ff:ff:ff:ff:ff, vlan 4, spoof checking off, link-state auto, trust off }}} [[CollapsibleEnd]] [[CollapsibleStart(Run the 5G Core)]] {{{#!shell root@srv1-lg1:/opt/amarisoft/ltemme-linux-2024-09-13# ./lte_init.sh Select enp134s0f0 enp94s0f0np0 default interface Configure NAT for enp134s0f0 Configure NAT for enp94s0f0np0 net.ipv4.tcp_congestion_control = bbr net.core.rmem_max = 62500000 net.core.wmem_max = 62500000 root@srv1-lg1:/opt/amarisoft/ltemme-linux-2024-09-13# ./ltemme config/mme.cfg Core Network version 2024-09-13, Copyright (C) 2012-2024 Amarisoft This software is licensed to Rutgers University (The State University of New Jersey).
