Hello USRP-users mailing list,
We are using an X310 for OpenAirInterface (OAI). It has one RF card.
I wonder the following:
* With the following configuration:
* USRP X310, HG image, one RF card
* host connected to USRP through 1*10Gbps and 1*1Gbps
* I run OAI on the 10Gbps ethernet interface, and while it is running I
tried to run an other instance via the 1Gbps ethernet interface. I didn't
expect it to work, but I didn't expect neither the error message: uhd tells me
that no USRP was found (I made sure it looks-up through the 1Gbps interface).
* My interpretation is that once that all of the available RF cards have
an established link with the host, USRP closes all of the free interfaces
(PCIe, ethernet...)
* Thus, if I put an other RF card, and tell the USRP to use only one
ethernet interface per RF card, then I would be able to run one OAI instance
through an ethernet interface + an RF card, and an other instance through the
other ethernet interface + the other RF card. Is it correct?
* Now if we consider the N310, its 4 RF cards and its 2 ethernet
interfaces: (ignoring limitation from OAI bandwidth requirements) is it
possible to run two instances of OAI through a single ethernet interface, so
that I could run four instance through two ethernet interfaces?
* If all of the above is correct, do you have any idea on how to achieve
this?
Thank you
Regards,
Rodolphe
