Hi Marcus^2, Thanks for taking a look at this.
Yes, I am using 10G interface, but you will notice my streaming request was only at 200Mbps (via command —rate=200e6). > ``` > eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 > inet 192.168.0.67 netmask 255.255.255.0 broadcast 192.168.0.255 > inet6 fe80::3eec:efff:fec2:4346 prefixlen 64 scopeid 0x20<link> > ether 3c:ec:ef:c2:43:46 txqueuelen 1000 (Ethernet) > RX packets 16068286 bytes 7458604025 (7.4 GB) > RX errors 0 dropped 113 overruns 0 frame 0 > TX packets 11987991 bytes 3951547409 (3.9 GB) > TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 > > eno2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 > inet 192.168.30.1 netmask 255.255.255.0 broadcast 192.168.30.255 > inet6 fe80::3eec:efff:fec2:4347 prefixlen 64 scopeid 0x20<link> > ether 3c:ec:ef:c2:43:47 txqueuelen 1000 (Ethernet) > RX packets 5544521276 bytes 44302674870930 (44.3 TB) > RX errors 0 dropped 0 overruns 0 frame 0 > TX packets 61549463 bytes 5108838143 (5.1 GB) > TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 > > eno2:0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 > inet 192.168.30.30 netmask 255.255.255.0 broadcast 192.168.30.255 > ether 3c:ec:ef:c2:43:47 txqueuelen 1000 (Ethernet) > ``` You can add eno2:0 through this command “sudo ifconfig eno2:0 192.168.30.30 netmask 255.255.255.0 up”, but keep in mind if you reboot you will lose it. tcpdump is promiscuous, so it would see any traffic on 192.168.30.X network. Point taken on rfnoc, but take a look at source is in /uhlib/usrp/cores/xport_adapter_ctrl.hpp as you look for the other error message “Device was unable to look up Ethernet (MAC)…”. You will also notice the check for for an “arp” with a retry count of 3. Thanks, —Cy
