Hi,

I also noticed something odd.
When I run the flowgraph on the machines. Tx and Rx LEDs are one on both USRPS.
However as soon as I assign an IP Address to the virtual eth cards, the Rx LED on one of the USRPs goes off.
It happens randomly so sometimes it is PC1 side and sometimes PC2.

Cheers.

I'm going to assume the B210 isn't using the IP address

  192.168.200.1

Can you ping the B210 from PC1?

The B210 should be using the IP address

  192.168.200.2

Unless you create a virtual Ethernet device on PC2 you'll never be able
to ping the PC1 or the B210 from PC2.

Also, post the outputs of

  ifconfig

for PC1 and PC2.

Also, I don't know anything about the B210 - it may not be possible to
do what you're trying to do - but try it anyway.
