From the log file that is generated, we can monitor several important steps, to assess that the test was successful: From the log file that is generated, we can monitor several important steps, to assess that the test was successful:
Step **6. Random Access Procedure** is successfully reached when the following messages are shown:
[X2AP ... Received elements for X2P]
...
[LSCH received ok]
The next message to check is: - eNB receives UE capabilities information, including its NR capabilites, and triggers sGNB Addition Request message:
[DCI type I payload] indicating some DL traffic for signaling
Eventually, step **12. E-RAB Modification Confirmation** is successfully reached when the following message is visible: ***eNBlog.1315 :***
[E-RAB Modification Confirmation], the message is properly received but not treated. ```

- gNB receives sGNB Addition request, processes UE capabilities for the corresponding UE and triggers sGNB Addition Request ACK, carrying NR RRC Reconfiguration message:
***gNBlog.2291 :***

- Upon reception of the sGNB Addition Request ACK, the eNB sends a new RRCConnectionReconfiguration message containing the NR Reconfiguration.
The UE replies with a Reconfiguration Complete message:
***eNBlog.1686 :***
```
[RRC] [FRAME 00000][eNB][MOD 00][RNTI 43eb] UE State = RRC_RECONFIGURED (default DRB, xid 1)

- The Random Access procedure of the UE to the gNB takes place:

- The eNB triggers the path switch procedure towards the MME, so that
the traffic can be routed now from the SGW towards the gNB on the S1-U
plane.
