By default there is no probe traffic for IPMP. Link health is based on the state of the link, not an ICMP ping. This means that if your switch or network fails, but the link does not fail, then it will not be detected by IPMP. Not by coincidence, this is how link aggregation works, too. If you actually want to test that your network is working (as opposed to the switches) then you'll need to configure probes. -- richard > > Am I missing anything or are these our options?
