Ethernet bonding -- link layer detection failover isn't enough, smarter detection?

Hi everyone,

We run redundant switches that two nic's on each server connect to. We also run bonding on our servers. Because we have two switches, we can't run lacp or anything. If a switch goes into a crashed state where it doesn't pass traffic but still provides link, bonding thinks the interface is still up and thus will still send traffic through it. Does anybody know a better way to configure the fail over of the interface? This would be a similar situation to somebody using a media converter.

You can use arp link monitoring by passing the 'arp_interval' and 'arp_ip_target' options to the bonding driver instead of 'miimon'.
