Hi, I have a problem with the N321 USRP. I find packet droppedin USRP but not in host. In host, I am running Ubuntu 18.04.
Below is the ifconfig result in N321: root@ni-n3xx-320CAAB:~# ifconfig eth0 Linkencap:Ethernet HWaddr 00:80:2F:32:36:BA inetaddr:192.168.10.165 Bcast:192.168.255.255 Mask:255.255.255.0 UPBROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RXpackets:618374 errors:0 dropped:11485 overruns:0 frame:0 TXpackets:193714 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RXbytes:39776733 (37.9 MiB) TX bytes:14546432 (13.8 MiB) Interrupt:27 Base address:0xb000 int0 Link encap:Ethernet HWaddr AE:CD:BA:E1:CF:96 inetaddr:169.254.0.1 Bcast:169.254.0.255 Mask:255.255.255.0 UPBROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RXpackets:456 errors:0 dropped:0 overruns:0 frame:0 TXpackets:15 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RXbytes:37392 (36.5 KiB) TX bytes:2770 (2.7 KiB) lo Linkencap:Local Loopback inetaddr:127.0.0.1 Mask:255.0.0.0 UPLOOPBACK RUNNING MTU:65536 Metric:1 RXpackets:89 errors:0 dropped:0 overruns:0 frame:0 TXpackets:89 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RXbytes:7480 (7.3 KiB) TX bytes:7480 (7.3 KiB) sfp0 Linkencap:Ethernet HWaddr 00:80:2F:32:36:BB inetaddr:192.168.12.2 Bcast:192.168.12.255 Mask:255.255.255.0 UPBROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RXpackets:6239 errors:0 dropped:804 overruns:0frame:0 TXpackets:5669 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RXbytes:18466697 (17.6 MiB) TX bytes:18417536 (17.5 MiB) sfp1 Linkencap:Ethernet HWaddr 00:80:2F:32:36:BC inetaddr:192.168.13.2 Bcast:192.168.13.255 Mask:255.255.255.0 UPBROADCAST RUNNING MULTICAST MTU:9000 Metric:1 RXpackets:24868 errors:0 dropped:796 overruns:0 frame:0 TXpackets:24613 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RXbytes:20486915 (19.5 MiB) TX bytes:19611643 (18.7 MiB) Below is ifconfig result in host: user@USRP-SERVER:~$ ifconfig eno1:flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet192.168.10.143 netmask 255.255.255.0 broadcast 192.168.255.255 inet6fe80::b27b:25ff:fe1d:9e4e prefixlen 64 scopeid 0x20<link> etherb0:7b:25:1d:9e:4e txqueuelen 1000 (Ethernet) RX packets5604 bytes 416435 (416.4 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets404 bytes 68556 (68.5 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt16 memory 0xd2100000-d2120000 enp1s0f0:flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 inet192.168.12.1 netmask 255.255.255.0 broadcast 192.168.12.255 inet6fe80::faf2:1eff:fe42:dddc prefixlen 64 scopeid 0x20<link> etherf8:f2:1e:42:dd:dc txqueuelen 1000 (Ethernet) RX packets294 bytes 35184 (35.1 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets395 bytes 37148 (37.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 enp1s0f1:flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 inet192.168.13.1 netmask 255.255.255.0 broadcast 192.168.13.255 inet6fe80::faf2:1eff:fe42:dddd prefixlen 64 scopeid 0x20<link> etherf8:f2:1e:42:dd:dd txqueuelen 1000 (Ethernet) RX packets9 bytes 2228 (2.2 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets72 bytes 7983 (7.9 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 21071 bytes 1497110 (1.4 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets21071 bytes 1497110 (1.4 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Could you please let me know what is the possible reason forpacket drop in USRP?
