IPMI message handler: BMC returned incorrect response
Dear Dell Experts,
we are encountering the following repeated IPMI communication errors in the system logs (dmesg output below) of our Linux server (CentOS 7, model PowerEdge R510):
ipmi_si dmi-ipmi-si.0: IPMI message handler: BMC returned incorrect response, expected netfn 7 cmd 24, got netfn 4 cmd 3d
However, remote ipmitool commands are working correctly, and we are using IPMI version 2.0.
Could you please address the following questions?
What does the mismatch "expected netfn 7 cmd 24, got netfn 4 cmd 3d" indicate?
Are there recommended settings (BIOS, iDRAC, IPMI) to mitigate or eliminate these errors?
No Events found!

Hello,
The error message "expected netfn 7 cmd 24, got netfn 4 cmd 3d" indicates a mismatch in the expected and received IPMI commands. This typically happens when the system receives an unexpected command or response, which can be due to several reasons:
Firmware or Software issues
Configuration Problems
Network Issues
I would start with making sure the BIOS an iDRAC are up to date from the R510 support page:
https://www.dell.com/support/product-details/en-us/product/poweredge-r510/drivers
Then I would also verify in the iDRAC - iDRAC settings- IPMI Settings that Enable IPMI over LAN is enabled and the privilege level limit, and if your authorization matches.
This resource should help:
*Configuring Your iDRAC6 page 42
*Configuring the Network and IPMI LAN Settings page 54
*Table 4-5. IPMI Settings page 59
*Configuring IPMI page 66
