Software installation and deployment

This section describes the installation of the O-DU High on the reference hardware.

Libraries

Following libraries are required to compile and execute O-DU High:

  • GCC
    • Ubuntu : sudo apt-get install -y build-essential

    • CentOS : sudo yum groups mark install -y “Development Tools”

    Ensure the version is 4.6.3 and above using

    • gcc –version

  • LKSCTP
    • Ubuntu : sudo apt-get install -y libsctp-dev

    • CentOS : sudo yum install -y lksctp-tools-devel

  • PCAP:
    • Ubuntu : sudo apt-get install -y libpcap-dev

    • CentOS : sudo yum install -y libpcap-devel

Cloning code

  • Create a folder to clone the O-DU High code into. The folder is hereafter referred to as <O-DU High Directory>.

  • Clone code into <O-DU High Directory>

    git clone “https://gerrit.o-ran-sc.org/r/o-du/l2

Setting up Netconf server (Only if O1 interface enabled)

Following steps are required to compile and run ODU with O1 interface enabled.

  • Create a new netconf user

    Switch to root user or use sudo and run following commands

    • Ubuntu :
      cd <O-DU High Directory>/l2/build/scripts
      sudo ./add_netconf_user.sh
  • Install Netconf libraries:

    libssh, libyang, libnetconf2, sysrepo, netopeer2

    Script is provided in the following folder to install these libraries

    • Ubuntu :
      cd <O-DU High Directory>/l2/build/scripts
      sudo ./install_lib_O1.sh -c
  • Install the YANG modules and load initial configuration

    • Navigate to config folder and update the desired initial configuration

      cd <O-DU High Directory>/l2/build/config
      Open the startup_config.xml and edit the desired IP and Port for CU, DU and RIC.
      Open the nacm_config.xml and edit the desired user name to provide the access to that user.
      Open the netconf_server_ipv6.xml and edit the desired netconf server configuration.
      Open the oamVesConfig.json and edit the details of OAM VES collector.
      Open the smoVesConfig.json and edit the details of SMO VES collector.
      Open the netconfConfig.json and edit the details of Netopeer server.
      Install the yang modules and load initial configuration.
      • Ubuntu :

      $cd <O-DU High Directory>/l2/build/scripts
      $sudo ./load_yang.sh
    • To enable Standard Defined VES format:

      cd l2/src/o1/ves
      Enable the Macro “StdDef” in file VesUtils.h
      #define StdDef
  • Start Netopeer2-server:

    • Ubuntu :
      cd <O-DU High Directory>/l2/build/scripts
      sudo ./netopeer-server.sh start
