Please review LiteON O-RU configuration for DGX Spark + FibroLAN Falcon RX + Aerial Testbed 1.0

Accelerated Computing Aerial Forum

Hi NVIDIA Aerial team,

We are currently bringing up an O-RAN testbed with the following setup:

  • Server: DGX Spark
  • Timing / PTP: FibroLAN Falcon RX
  • O-RU: LiteON O-RU
  • Software: Aerial CUDA-Accelerated RAN / cuBB 26-1
  • Testbed: Aerial Testbed 1.0

The LiteON O-RU has already synchronized to PTP and the RF state is ready, but the O-RU still reports DuConnected : notReady.

Current LiteON O-RU configuration:

# show running-config

Band Width = 100000000
Center Frequency = 3750000000
Compression Bit = 9
Control and User Plane vlan = 2
M Plane vlan = 100
default gateway = 10.101.131.254
dpd mode : Enable
DU MAC Address = 4cbb472ff26b
phase compensation mode : Enable
RX gain = 14
TX power = 24
subcarrier spacing = 1
rj45_vlan_ip = 10.101.131.61
SFP_vlan_ip = 10.101.131.62
SFP_non_vlan_static_ip = 192.168.1.100
prach eAxC-id port 0, 1, 2, 3 = 0x0004, 0x0005, 0x0006, 0x0007
slotid = 0x00000001
jumboframe = 0x00000001
sync source : PTP

O-RU status:

# show oru-status

Sync State  : SYNCHRONIZED
RF State    : Ready
DPD         : Ready
DuConnected : notReady

Our current assumption is that the PTP side is working correctly, and the remaining issue is likely related to C/U-plane connectivity or parameter mismatch between the Aerial DU configuration and the LiteON O-RU configuration.

Could you please review the above LiteON O-RU settings and advise whether any of them should be changed for DGX Spark + FibroLAN Falcon RX + LiteON O-RU + Aerial Testbed 1.0?

Thanks.

RU config and L1 config look good. The only change I have is

# show running-config 
Band Width = 100000000
Center Frequency = 3750000000
Compression Bit = 9
Control and User Plane vlan = 564
M Plane vlan = 0
default gateway = 10.101.131.254
dpd mode : Enable
DU MAC Address = 9c63c0f426d2
phase compensation mode : Enable
RX gain = 14
TX power = 24
subcarrier spacing = 1
rj45_vlan_ip = 10.101.131.61
SFP_vlan_ip = 10.101.131.62
SFP_non_vlan_static_ip = 192.168.1.100
prach eAxC-id port 0, 1, 2, 3 = 0x0000, 0x0001, 0x0002, 0x0003
slotid = 0x00000001
jumboframe = 0x00000001
sync source : PTP

and L1 config
eAxC_id_prach: [0, 1, 2, 3]

Can you check that FH communication is working?

Hi @fmolander

It can now connect successfully, but we found that the stability is relatively poor, and it is much less stable than the WNC O-RU.

If we want to improve the stability, which aspects should we focus on optimizing?

I have only tested Liteon on Grace Hopper. For reference please have a look at my L1 config for Liteon.
With UEsim i could do 1000Mbps DL and 120Mbps UL.
