Hi Fernando, This mgt port is used since at the beginning of installation, written into system inventory and is being used all the time in StarlingX system. My understanding is that it is less likely StarlingX provides an interface to change it after the system is deployed. Anyway, what’s your motivation to make such a change?? regards, Yong From: "Hernandez Gonzalez, Fernando" <fernando.hernandez.gonzalez@intel.com> Date: Friday, 25 January 2019 at 11:41 PM To: "starlingx-discuss@lists.starlingx.io" <starlingx-discuss@lists.starlingx.io> Subject: [Starlingx-discuss] Looking a command that changes Virtual host node MAC Addr.
