Query on USRP2 and Host device Communications

Hi All

I have a query motivated by the fact* *" USRP 2 device is communicating
through an ethernet cable
with an IP address"

given multiple host machines and multiple USRP2 devices connected over a
network.Is it possible to make sure
that give USRP device will communicate with a particular host machine
over
the network only. *
*
Based on this Query we have following questions.Kindly please help us in
clarify the following.

  1. How does host PC running Gnuradio detects a USRP device?
  2. In case of initial handshaking whether the USRP device or host
    machine
    initiates the handshake?
  3. After the initial handshake ,how will the host machine keep track of
    the
    USRP device address?

Thanks in advance for the clarifications…

Thanks

Communications are generally initiated by the host.

If you
explicitly specify the target device address using “addr=”, then the
host will communicate only with that USRP2 for the corresponding
flow-graph.

The USRP2 has no firewalling abilities or anything like
that, and doesn’t really use an IP routing stack, so the intention is
that it sit on a dedicated host-to-USRP2 Ethernet Link. It really isn’t
intended to live in a regular, routed IP environment.
