I can only quote jpirko's workds from the link above: 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 just tested mode 4, and the LACP with Fedora 20 appears to not be compatible with the LAG mode on my Dell 2824. Would there be any issues with bringing two NICS into the VM and doing balance-alb at the guest level? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[ovirt-users] 答复: bond mode balance-alb
HI, Blaster I test blance-alb and works well. But I modified the ifcfg-bond.cfg manually and restart the ovirt-engine service, then the modification will be reflacted in the GUI automatically.

I’m using Dell 2824 switches which support LAG (static 802.3ad apparently?) but not LACP (dynamic 802.3ad). Fedora only seems to support Dynamic mode from what I can tell. The next best choice seems to be balance-alb, but for some reason it’s not available as a mode in the drop down. Any reason why it’s missing? If I select custom and enter balance-alb, is that supported? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
