You can change the polling interval with the miimon option, but I'm not sure how precise you can get, it does take some time for the system to register a link failure, if that is infact what causes the network to fail. Another failure mode is a layer 2 failure which can detected in some cases using the arp monitor. I think rather than trying to achieve zero loss on the network with regards to failures you should tune the cluster to be more tolerant and not raise a fit if the network is down for a second or two. nate
