I recently bought an i350 ethernet controller. I would like to enable the "critical manageability session" of the card, but I can't find any documentation that explains how to do that. The only document related to my question is https://www-ssl.intel.com/content/dam/www/public/us/en/documents/guides/maintaining-the-ethernet-link-to-the-BMC.pdf# page=7&zoom=auto,70,298 https://www-ssl.intel.com/content/dam/www/public/us/en/documents/guides/maintaining-the-ethernet-link-to-the-BMC.pdf# pag… which says to refer to the i350 documentation. I did... but I was not able to find any concrete information in it. Any hint?
Try check on below documentation about the manageability session.
Please do let me know if above info help.
Thanks for the information. Unfortunately the i350 data-sheet and the document you sent me don't contain useful information to activate the critical manageability session. In your document the only related paragraph ("Overriding MAIN_PWR_OK") explains how to keep the critical manageability session once it has been activated, but does not explain how to activate it. Same comment for the official data-sheet (I've tried everything related to the critical session but so far failed to activate it).
Do you have any tool / precise guideline / (ipmi) command line to activate this feature? (Or know somebody that would know how to do that )
Good day. Further checking, you need to have an onboard NIC or LOM design which has BMC in order to enable critical session. The BMC can configure the critical session via the sideband interface and prevent the loss of link.
Hope this clarified.
