The downside of > it is that I cannot find out when connections beyond > the first switches are going down :( Let me clarify some things, are these correct?: o Failover works when using MII monitoring, if one *or both* systems are up. o Failover also works using ARP monitoring, providing only 1 system is up. o Failover does not work using ARP when both systems are up. o Failure is exhibited by the interface connected to the *working* route being marked bad. And some further observations: o The network diagramme you provided shows both interfaces on each host have the same MAC address, but ifconfig shows different MAC's for each interface, and neither corresponds to the bonding MAC. o Likewise the IP address you specify in the diagramme is different from that used by the bonding device. o You specify a primary interface, which may not strictly be necessary o You specify only 1 ARP target, which probably doesn't matter in this configuration as it is the end-point switch. With that in mind, my next advice would be to check the MAC addresses and IP addresses used on the hosts do not clash, and are correct. It would also be good if you could update the web page so that information from both hosts are side-by-side, in 2 columns. This would make it much easier to see if there is any collision or misconfiguration.
