Hello everyone,
I am having a strange (new) problem where my host machine can not
detect more than one USRP at a time. I recently re-installed
everything to update all devices to 3.13.1.0.
Each of my N310's SFP+0 ports is configured as follows:
MTU: 8000
Address: 192.168.5x/24
Where x is the device number I have assigned (1-9).
What is bizarre is if two N310's are connected to the host, only
one shows up in uhd_find_devices.
Each N310 connects fine on its own. Just plug and play. But
attaching more than one to the server breaks things.
The server is manually configured with a different static ip for
each SFP+ port:
192.168.20.2y
Where y is the port number (0-6).
Everything (SD file system, host install, FPGA, ixgbe driver) is
up to date. I can do whatever I want if only one device is
attached (SSH, UHD commands, GNU radio, device_probe).
I'm not sure what to do about this as individually all of them
work perfectly. Any ideas?
Thank you for your time,
Ali
Having two NICs on your server living on the same subnet (192.168.20) is
likely to not work because that's not how the IP routing machinery works in
most host operating systems--the routing machinery will use the first
port it finds that "matches" the desired destination address subnet.
