#### MICROAMP FR2
|
||||
|
||||
|
||||
Interaction with RU is performed using `rucfg` utility provided by Microamp.
|
||||
|
||||
To check PTP status, you can use `rucfg ptp`. the output should be similar to:
|
||||
```bash
|
||||
[INFO] Check if RU is available
|
||||
[INFO] RU available
|

[INFO] Check SSH to RU available

##### RU configuration
|
||||
|
||||
You can use `rucfg show` to display the current RU configuration.
|
||||
|
||||
The OAI configuration file [`gnb.sa.band257.132prb.fhi72.2x2-microamp.conf`](../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band257.132prb.fhi72.2x2-microamp.conf) corresponds to the following RU configuration:
|
||||
|
||||
```bash
|
||||
[INFO] Check if RU is available
|
||||
[INFO] RU available
|
||||

}
|
||||
```
|
||||
|
||||
Execute `rucfg config -h` to check how to configure the RU.
|
||||
|
||||
You can also execute `rucfg stats` to show fronthaul statistics including on-time/late packet' counters.
