To make sure, do: - CU Configuration ``` shell= cd openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF sudo nano cu_gnb.conf ``` ![](https://hackmd.io/_uploads/rJtgblUrh.png) - DU Configuration ``` shell= cd openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF sudo nano du_gnb.conf ``` ![](https://hackmd.io/_uploads/B1aCfeIH3.png)
