I found that I while I can get LACP working properly using eth0 and eth1, using the exact same setup with any of the other three lan fails. Is this a known issue? This is on Linux 2.6.32.10. Here is a blurb of dmesg showing the NICs detected. eth0: RTL8168b/8111b at 0xf8adc000, 00:30:18:ac:a6:80, XID 0c200000 IRQ 24 eth1: RTL8168b/8111b at 0xf8ae0000, 00:30:18:ac:a6:81, XID 0c200000 IRQ 25 eth2: RTL8169sc/8110sc at 0xf8ae4c00, 00:30:18:ae:34:3a, XID 18000000 IRQ 18 eth3: RTL8169sc/8110sc at 0xf8ae8800, 00:30:18:ae:34:3b, XID 18000000 IRQ 19 eth4: RTL8169sc/8110sc at 0xf8aec400, 00:30:18:ae:34:3c, XID 18000000 IRQ 16 I can probably manage this project using only eth0 and eth1 in LACP configuration but I figured I'd give a heads up. The interfaces seem able to detect when the link is up or down, bonding removes and adds them to the LACP trunk but I can't get traffic through them. Kind regards, Jonathan
