Thanks to Kiran on https://github.com/apache/cloudstack/pull/10630#issuecomment-2811728467 who has found indeed POST must be used.
Further, to answer my own question, it's further confirmed by Dell and Supermicro docs: https://downloads.dell.com/solutions/dell-management-solution-resources/Implementation%20of%20the%20DMTF%20Redfish%20API%20on%20Dell%20EMC%20PowerEdge%20Servers.pdf https://www.supermicro.com/manuals/other/redfish-ref-guide-html/Content/general-content/bmc-configuration-examples.htm#system-reset Regards. ________________________________ From: Rohit Yadav <rohit.ya...@shapeblue.com> Sent: Thursday, April 17, 2025 08:57 To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: Redfish OOBM plugin All, Can any user confirm if their real-world Redfish oobm/bmc: * uses ports other than port 80 or 443 * uses HTTP POST (or GET) for power actions such as on/off/reset/cycle and for power status check?
