[ovirt-users] bonding mode-alb

[Demeter Tibor]

Hi, 

Thanks for the answers. 

In this case the only question is: what is better for me? Mode 5 or 6? 
In which modes how is fast the switching? 

Until now I've use 802.3ad lacp on our old cluster. I did some tests and it was very fast. I know it is not same, but mode 5 or 6 how is safe? 
Thanks 

Regards, 

Tibor
