IPMI's speed or duplexity settigns are not always negotiated properly with different switches and/or routers, so the connection may break.
Not all of our products can be set using the commands from this article, please see the details at the bottom of the article.
IPMI is unreacheable after a short amount of time.
The manufacturer of the IPMI firmware made an option to set it.
The dedicated IPMI interface speed and duplexity settings can be set with the ipmitool utility's raw commands with OEM command format:
NetFn:0x30 / CMD:0x70 / SubCMD:0x63
Data 1: 0/1 [Get/Set]
Example for setting it to auto-negotiate the link:
ipmitool raw 0x30 0x70 0x63 1 0
