I confused about bond mode. I read from RHEV document: Modes 1, 2, 3 and 4 support both virtual machine (bridged) and non-virtual machine (bridgeless) network types. Modes 0, 5 and 6 support non-virtual machine (bridgeless) networks only. And in oVirt i can not choice bond mode 0 ,but can choice bond mode 5. But in my host , i use bond mode 0 two years, It is work fine. Can someone explain this,thk!
Which network was defined on your bond mode 0 for two years? Was it a VM network? Or did have some other role? mode 0 may work for VM networks by accident. But it is not to be used. I can only share jpirko words again: https://bugzilla.redhat.com/show_bug.cgi?id=1094842#c0 Do not use tlb or alb in bridge, never! It does not work, that's it. The reason is it mangles source macs in xmit frames and arps. When it is possible, just use mode 4 (lacp). That should be always possible because all enterprise switches support that. Generally, for 99% of use cases, you *should* use mode 4. There is no reason to use other modes.

I think 99% may be a bit high... what if one wants to split the bond between two or more non-stacked switches, which I would imagine is a pretty common scenario. My understanding is if mode 4 (LACP) is used, all the interfaces need to be connected to the same switch, no? Regards, Alan
