IPMI will not grab IP even with DHCP turned on : homelab

Posted by jpluimers on 2021/08/13

TL;DR

  1. ensure the IPMI network cable is connected before connecting the power cable
  2. ensure the IPMI LAN is using the dedicated interface
  3. ensure the IPMI LAN interface is connected to a “non green” port of your network switch
  4. ensure the DHCP server has been cold rebooted
  5. ensure the IPMI VLAN configuration matches your network
  6. ensure the IPMI firewall configuration matches the network you try to reach IPMI from
  7. ensure the motherboard does not have a short-circuit anywhere

Otherwise SuperMicro devices might not get a DHCP address on the IPMI (BMC) interface, despite the tooling like [WayBack] ipmicfg indicating getting DHCP was succesful.

This especially holds for X9 boards, likely for newer boards as well.

Personally I never had the 4. and up above, but I bumped into 1. and 2. with SuperMicro boards and 3. with other devices.
