Yes, thanks Corey. I saw that just after I had clicked Send. :-/ But the version of ipmitool would be important to know.

I don't really see a problem, except it looks to me like the BMC is very slow and ipmitool retransmits a few times. From what I can tell, those are retry responses and ipmitool correctly recognizes them. ipmitool should just ignore them, but I can't tell from this output if it does. -corey > > > IP - 192.168.1.1 > > MAC - 192:168:1:1:0:0 > > > > IP Address parameter response is taken for MAC Address parameter > response.
