I am getting RX packet drop on
eth0 interface on Linux ( but not on eth1)
bond0 : RX packets:575214161 errors:0 dropped:6407 overruns:0 frame:0 eth0 : RX packets:573623915 errors:0 dropped:6410 overruns:0 frame:0 eth1 : RX packets:1590356 errors:0 dropped:0 overruns:0 frame:0
I have check MRTG to see traffic flow and its around ~30mbps
But interesting thing. I am seeing all 30mbps traffic on eth0, eth1 has few kbps traffic. That means my link is not doing load balancing right?
cacti reporting following data. LACP should share traffic on both link right?
eth0: 30mbps eth1: 600kbps
