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:
I cannot help with srsRAN, maybe others know more about it.
But your N310 is essentially working, and your issue is likely with
configuration of your application (srsRAN?).

Hi Marcus
I ran the benchmark command on both ip of the n310 and attached
you can find the printout.
I"m going to guess that one of your interfaces is operating at
1Gbit, while the other is operating at 10Gbit?
I don't know what rates the srsRAN software runs the interface at,
but clearly in your 2nd example, on the
other IP, it's able to support 25Msps without any issue.

Many thanks for prompt reply Marcus! Please find attached
the printout for that probe command you asked for.
OK, so the next thing to do is to test your network capacity
between your host computer and the N310:
benchmark_rate --args
"type=n3xx,product=n310,addr=10.10.0.100,master_clock_rate=125e6"
--rx_rate 25e6 --tx_rate 25e6

I am running srsRAN gNB on my server (/Commit
9d5dd742a/). A version of srs of srsRAN that is
compiled with /UHD 4.7.0.0./
Here are the error messages I get:

And obviously it is not working with this amount of errors.
Can anyone help me with this please? Is it a bug in the
UHD version? Or is there something I am missing here?
Thanks
Houshang
Try "the basics" first.
What does:
uhd_usrp_probe --args
"type=n3xx,product=n310,addr=192.168.10.2"
Produce (you might have to change the addr to whatever
the address is of your N310).
