185 G. How to test with Intel L1:
186 -----------------------------
190 a. Create folder l2/src/wls_lib. Copy wls_lib.h from <intel_directory>/phy/wls_lib/ to l2/src/wls_lib.
191 b. Create folder l2/src/dpdk_lib. Copy following files from <intel_directory>/dpdk-19.11/x86_64-native-linuxapp-gcc/include/ to l2/sr c/dpdk_lib.
192 rte_branch_prediction.h
197 rte_pci_dev_feature_defs.h
207 make odu PHY=<refer section D.1.h> PHY_MODE=<refer section D.1.h> MACHINE=<refer section D.1.h> MODE=<refer section D.1.h>
209 2. Build CU Stub and RIC Stub:
210 a. Execute steps in sections D.3 and D.4
213 1. Refer to below link for assumptions, dependencies, pre-requisites etc for ODU-Low execution
214 https://docs.o-ran-sc.org/projects/o-ran-sc-o-du-phy/en/latest/
217 a. Setup environment:
218 cd <intel_directory>/phy/
221 cd <intel_directory>/FlexRAN/l1/bin/nr5g/gnb/l1
223 i. In timer mode : ./l1.sh -e
224 ii. In radio mode : ./l1.sh -xran
225 L1 is up when console prints follow:
227 Non BBU threads in application
228 ===========================================================================================================
229 nr5g_gnb_phy2mac_api_proc_stats_thread: [PID: 8659] binding on [CPU 0] [PRIO: 0] [POLICY: 1]
230 wls_rx_handler (non-rt): [PID: 8663] binding on [CPU 0]
231 ===========================================================================================================
233 PHY>welcome to application console
235 3. Execute FAPI Translator:
236 a. Setup environment:
237 cd <intel_directory>/phy/
239 b. Run FAPI translator binary:
240 cd <intel_directory>/phy/fapi_5g/bin/
241 ./oran_5g_fapi --cfg=oran_5g_fapi.cfg
243 4. Execute CU Stub and RIC Stub:
244 a. Run steps in sections E.1-E.3
247 a. DU execution folder
249 b. Export WLS library path
250 export LD_LIBRARY_PATH=<intel_directory>/phy/wls_lib/lib:$LD_LIBRARY_PATH
255 H. Push cell and slice configuration over O1 using netopeer-cli
256 ---------------------------------------------------------------
257 When O-DU High is run with O1 enabled it waits for initial cell configuration to be pushed by SMO before starting the stack. In case the SMO is not available then these configurations can be pushed via netopeer-cli as follows:
261 > connect --login netconf
262 Interactive SSH Authentication
265 > edit-config --target candidate --config=cellConfig.xml
269 > edit-config --target candidate --config=rrmPolicy.xml
274 For pushing these configurations in subsequent runs please edit cellConfig.xml and rrmPolicy.xml and increment number in the <id> tag to a new value e.g.
279 I. How to execute the Health Check using netopeer-cli : get alarm-list
280 -----------------------------------------------------------------------
282 In case the SMO is not available the alarm list can be checked using netopeer-cli as follows:
285 > connect --login netconf
286 Interactive SSH Authentication
289 > get --filter-xpath /o-ran-sc-odu-alarm-v1:odu/alarms
291 <odu xmlns="urn:o-ran:odu:alarm:1.0">
294 <alarm-id>1009</alarm-id>
295 <alarm-text>cell id [1] is up</alarm-text>
296 <severity>2</severity>
297 <status>Active</status>
298 <additional-info>cell UP</additional-info>
303 The XML output is a list of active alarms in the O-DU High system.
306 J. Troubleshooting Netconf server issues
307 ----------------------------------------
308 In case the Netconf server and sysrepo breaks down, run the following steps:
311 $sudo ./troubleshoot_netconf.sh cleanup
312 execute section C.3 and C.4 again
