I am seeing "down" on the box itself through "cphaprob state".

"Also, not defining the topology seems like a bad idea to me, especially since many cluster features depend on whats defined in the topo. If you don't want to do antispoofing then simply uncheck it once the interface topo is defined."

Where do you base this information from? I have eth4 "defined" as the
sync interface, NOT cluster interface.

I have an identical setup on NG with AI R55 hfa_20 with interfaces
undefined and it works just fine.
