Hello, I currently have an issue trying to stream packets through the SFP ports. Currently, when I ssh into the Ettus N321 and use ifconfig, I get the following output
> eth0 Link encap:Ethernet HWaddr 00:80:2F:35:25:BE > > inet addr:192.168.1.151 Bcast:192.168.1.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > > RX packets:108385 errors:211 dropped:0 overruns:96 frame:115 > > TX packets:92510 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:57550685 (54.8 MiB) TX bytes:25439541 (24.2 MiB) > > Interrupt:27 Base address:0xb000 > > int0 Link encap:Ethernet HWaddr 6E:C0:18:F0:B5:B5 > > inet addr:169.254.0.1 Bcast:169.254.0.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 > > RX packets:5342 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:1797 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:5608732 (5.3 MiB) TX bytes:123539 (120.6 KiB) > > lo Link encap:Local Loopback > > inet addr:127.0.0.1 Mask:255.0.0.0 > > UP LOOPBACK RUNNING MTU:65536 Metric:1 > > RX packets:116 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:116 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:10067 (9.8 KiB) TX bytes:10067 (9.8 KiB) > > sfp0 Link encap:Ethernet HWaddr 00:80:2F:35:25:BF > > inet addr:192.168.10.2 Bcast:192.168.10.255 Mask:255.255.255.0 > > UP BROADCAST MULTICAST MTU:9000 Metric:1 > > RX packets:0 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) > > sfp1 Link encap:Ethernet HWaddr 00:80:2F:35:25:C0 > > inet addr:192.168.20.2 Bcast:192.168.20.255 Mask:255.255.255.0 > > UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1 > > RX packets:0 errors:0 dropped:0 overruns:0 frame:0 > > TX packets:28 errors:0 dropped:0 overruns:0 carrier:0 > > collisions:0 txqueuelen:1000 > > RX bytes:0 (0.0 B) TX bytes:5252 (5.1 KiB) However, when I try to stream through the address port, either sfp0 or sfp1, I get the following timeout error > \[ERROR\] \[RFNOC::MGMT\] EnvironmentError: IOError: Timed out getting recv > buff for management transaction > > \[ERROR\] \[RFNOC::GRAPH\] IO Error during GSM initialization. > EnvironmentError: IOError: Timed out getting recv buff for management > transaction > > \[ERROR\] \[RFNOC::GRAPH\] Caught exception while initializing graph: > EnvironmentError: IOError: Timed out getting recv buff for management > transaction I have double checked my host computer configuration and it appears again that I am using the correct configuration. When I use “uhd_find_devices"“, it appears the address used for data is the same that is used for management, even though my guess is the argument “addr” should be either “192.168.10.2” or “192.168.20.2”. I believe this is probably related to the error I am receiving, however, I am unsure how to proceed from here. The output of uhd_find_devices is as follows… > -------------------------------------------------- > > \-- UHD Device 0 > > \-------------------------------------------------- > > Device Address: > > serial: 3255102 > > addr: 192.168.1.151 > > claimed: False > > fpga: HG > > mgmt_addr: 192.168.1.151 > > name: ni-n3xx-3255102 > > product: n320 > > type: n3xx Thanks Joe
