This is my first post to this website. I this that my question is related to serverfault cause it is related to ethernet communication issue. If you disagree please let me know what is the appropriate place to move this post to. Thanks.
I am using USB3 to GigE converter - since I don't have GigE on my linux board. My problem is after connecting to an IP camera. It works for sometime and I am able to receive images but then it stops after one or two minutes. After it stops I cannot ping anything and I can see there are error in rx packets.
Here is my
ifconfig before connecting to the camera:
ifconfig eth1 Link encap:Ethernet HWaddr 00:13:3b:99:28:56 inet addr:192.168.0.117 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::213:3bff:fe99:2856/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:4000 Metric:1 RX packets:102 errors:0 dropped:0 overruns:0 frame:0 TX packets:39 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:29172 (29.1 KB) TX bytes:6614 (6.6 KB)
and here is the same after connecting to the camera and stops responding:
ifconfig eth1 Link encap:Ethernet HWaddr 00:13:3b:99:28:56 inet addr:192.168.0.117 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::213:3bff:fe99:2856/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:4000 Metric:1 RX packets:137338 errors:1604 dropped:0 overruns:0 frame:0 TX packets:3662 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:274563593 (274.5 MB) TX bytes:287885 (287.8 KB)
Clearly there are error in RX packets, I am not sure why.
Here is the
ethtool eth1 output:
