In response to David: I'm not sure if this will offer any help but the new intel bmc's have dedicated MAC's for ipmi traffic and seperate MAC's for OS. Therefore it might be that the e1000 driver is not providing a multiplexor type operation correctly for discriminating between OS and IPMI traffic. Intel provided a dedicated MAC for the BMC for the reason that IPMI communication was not always reliable if MAC was shared, and problems were encountered such as you are seeing + bandwidth issues. I hope this helps, but as supermicro tools: ipmiview and ipmicli work reliably, i am unsure if the issues you are experiencing are related to the information i have given you. It may be that these tools provide different authentication steps to ipmitool, which enable them to work more reliably with the e1000 driver. If you give more detail (-vvvv), the data may give more insight. Thanks Tom Nabarro ------------------------------
