Hi Marcus,
Thank you for responding.
I can confirm that the USRP (192.168.30.2) and host (192.168.30.1) are
working (streaming data), as I wanted to verify before trying the
remote streaming.
I have added the 192.168.30.30 as second interface on the host, and it
is responding to pings. I do not have any firewall, they are all the
same LAN / subnet.
Based on the error “Requested remote UDP streaming, but transport
adapter sfp1 does not support it!”, it doesn’t seem like the program
is getting that far. I can also confirm that "sfp1” is the proper
interface with the ipaddr 192.168.30.2.
When monitoring the ethernet traffic, I never see a data packet with a
source of 192.168.30.2 to a destination of 192.168.30.30.

I do not have an active listener on dest udp, but I also don’t see any
traffic trying to set up a connection with 192.168.30.30.
There are no arps (when running program):

arp tcpdump: verbose output suppressed, use -v[v]... for full
protocol decode listening on eno2, link-type EN10MB (Ethernet),

There is no IP traffic with 192.168.30.30 (when program is running):
|cjohnson@demo:~/net$ sudo tcpdump --interface=eno2 -n host
192.168.30.30 tcpdump: verbose output suppressed, use -v[v]... for
full protocol decode listening on eno2, link-type EN10MB
(Ethernet), snapshot length 262144 bytes|
Is there a known working example with a stream listener on the remote
with a dest addr and dest udp port?
Not sure if relevant, and I can’t find any information on what each of
the address mean for USRP-2974, but the ip-addr0 and gateway are bogus
values below. I do have streaming connection from host 192.168.30.1 to
USRP 192.168.30.2, but still can’t get remote streaming to work.

To clarify, are you doing this on an external host, or on the embedded
x86 (i7) host inside the 2974?
