+C. Pre-requisite for O1 Interface (Required only if run with O1 interface enabled)
+-----------------------------------------------------------------------------------
+1. Setup netconf server
+
+ Create new netconf user (login with root user and run following commands)
+ $adduser --system netconf && \
+ echo "netconf:netconf!" | chpasswd
+
+ $mkdir -p /home/netconf/.ssh && \
+ ssh-keygen -A && \
+ ssh-keygen -t dsa -P '' -f /home/netconf/.ssh/id_dsa && \
+ cat /home/netconf/.ssh/id_dsa.pub > /home/netconf/.ssh/authorized_keys
+ Install netconf packages.
+ $cd l2/build/scripts
+ $chmod +x install_lib_O1.sh
+ $ ./install_lib_O1.sh -c
+
+2. Start Netopeer2-server:
+ $cd l2/build/scripts
+ $./netopeer-server.sh start
+
+3. Install the yang modules
+ $cd l2/build/yang
+ $sysrepoctl -i o-ran-sc-odu-alarm-v1.yang
+ $sysrepoctl -i o-ran-sc-odu-interface-v1.yang
+ $sysrepoctl -i o-ran-sc-du-hello-world.yang
+
+4. Configure the startup IP and Port configurations for DU, CU and RIC
+
+ $cd l2/build/config
+
+ Open the startup_config.xml and edit the desired IP and Port for CU, DU and RIC.
+ Then load the configuration in the sysrepo running datastore using the command below
+
+ $sysrepocfg --import=startup_config.xml --datastore running --module o-ran-sc-odu-interface-v1
+
+5. Configure the netconf server details for VES PNF Event
+
+ $cd l2/build/config
+
+ Open the netconfConfig.json and edit the desired MAC address, IP, Port, Username and Password for VES PNF Registration.
+
+6. Configure the VES server details to send VES Events
+
+ $cd l2/build/config
+
+ Open the vesConfig.json and edit the desired IP, Port, Username and Password to send VES Event.
+
+7. Configure the nacm module to provide access to new user
+
+ $cd l2/build/config
+
+ Open the nacm_config.xml and edit the desired user-name to provide the access to that user.
+
+ $sysrepocfg --import=nacm_config.xml --datastore running --module ietf-netconf-acm
+
+
+
+D. How to Clean and Build:
+--------------------------
+1. Build commands:
+ a. odu - Builds all components of ODU
+ b. cu_stub - Builds all CU Stub
+ c. ric_stub - Builds all RIC_Stub
+ d. clean_odu - clean up ODU
+ e. clean_cu - clean up CU Stub
+ f. clean_ric - clean up RIC Stub
+ g. clean_all - cleanup everything
+ h. options:
+ i. MACHINE=BIT64/BIT32 - Specify underlying machine type. Default is BIT32
+ ii. NODE=TEST_STUB - Specify if it is a test node. Mandatory for cu_stub/ric_stub. Must not be used for odu
+ iii. MODE=FDD/TDD - Specify duplex mode. Default is FDD
+ iv. PHY=INTEL_L1 - Specify type of phy. If not specified, PHY stub is used
+ v. PHY_MODE=TIMER - Specify mode of phy. Used only if PHY=INTEL_L1. Default is radio mode
+ vi. O1_ENABLE=YES - Specify if O1 interface is enabled. If not specified, it is disabled
+
+2. Building ODU binary:
+ a. Build folder
+ cd l2/build/odu
+ b. Building ODU binary
+ make odu MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+ c. Cleaning ODU binary
+ make clean_odu MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+
+3. Building CU Stub binary:
+ a. Build folder
+ cd l2/build/odu
+ b. Building CU Stub binary
+ make cu_stub NODE=<refer section D.1.h> MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+ c. Cleaning CU Stub binary
+ make clean_cu NODE=<refer section D.1.h> MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+
+4. Building RIC Stub binary:
+ a. Build folder
+ cd l2/build/odu
+ b. Building RIC Stub binary
+ make ric_stub NODE=<refer section D.1.h> MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+ c. Cleaning RIC Stub binary
+ make clean_ric NODE=<refer section D.1.h> MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
+
+5. Cleaning ODU, CU Stub and RIC Stub:
+ make clean_all
+
+
