10.10.0.100: I use it as the management ip of n310 and it is ETHERNET 1G.
10.10.2.100: I use it as the other ip of n310 for data and it is Fiber 10G.
With srsRAN I want to do 20MHz, TDD, N78 band, 2X2 MIMO. So DL will be
something around 120 Mbps and UL will be something around 11.5 Mbps.
But this issue happens before even Attaching a UE. Meaning I don't even run
data and I see this error:
