== 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
}}}
