#### 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
[INFO] 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
[INFO] Check SSH to RU available
[INFO] SSH to RU available
[INFO] Downloading oran_autostart
[INFO] Downloading ructl_config.sh
[INFO] Downloading udc_pll_configurator_startup

{
eCPRI Compression: True
RF Bandwidth: 200MHz
CC Bandwidth: 200MHz
CCs: 1
LO frequency: 7.91642667e9
UL compensation frequency: 28.04928e9
DL compensation frequency: -28.04928e9
RU MAC: 10:70:FD:B8:86:02
DU MAC: 50:7C:6F:31:00:61
TDD config: dddsu
RF Power level: -5 dB - relative to maximum
VLAN ORAN: Enabled, tag: 600
VLAN PTP: Enabled, tag: 1
VLAN MGMT: False

}
```
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.
