First thank you for your answer. Second it is not the case you described. If I leave only one machine online the bonding works very well. As soon as I bring online the second machine the bonding starts going crazy. I have the same configuration in both and it doesn't matter which one I shutdown and which one I let running. I also configured the bonding in active-backup mode with ARP monitoring, and as the documetation describe MII Status field in this case has no relevance. "down" doesn't mean the carrier signal is lost but the gateway cannot be reached like before (doesn't answer anymore to arpinging) As a side note I tried the same configuration with MII monitoring and it works perfectly. The downside of it is that I cannot find out when connections beyond the first switches are going down :( thanks again, Val __________________________________________________ Do You Yahoo!?
