iDrac Virtual NIC MAC conflict
Hi,
I installed new WS2012R2 server on our PowerEdge R540 server. Problem is that, some iDrac Virtual NIC appears in a list of NICs and this adapter has the same MAC as physical adapter:
name MacAddress ---- ---------- NIC2 D0-94-66-74-67-BC NIC1 D0-94-66-74-67-BB SLOT 6 Port 2 B0-26-28-14-F5-ED SLOT 6 Port 1 B0-26-28-14-F5-EC SLOT 5 Port 2 B0-26-28-14-F5-E3 SLOT 5 Port 1 B0-26-28-14-F5-E2 vEthernet (BackupExec LAN) B0-26-28-14-F5-E2 iDrac Virtual NIC D0-94-66-74-67-B8 Management Team D0-94-66-74-67-BB BackupExec Team B0-26-28-14-F5-E2 IntranetLAN Team B0-26-28-14-F5-EC
| iDRAC9 | 3.21.23.22 (Build 7) |
Is it possible to remove this iDrac Virtual NIC from this list or do we need it for some compatibility/support reasons ? Or Can I safely change MAC for this adapter in a configuration tab?
I am not sure, but looks that this is causing short outages of the server in our env. Ping goes up for a few seconds up till timed out, then it returns back to normal ~1ms. It happens on this server only and very rarely.. ~1-3 times per day, so I believe that this is not related to a switch
many thanks for help !

This is pass-through NIC configured by iDRAC. You can get more details on this interface from below link. This interface is also used if you have iSM (iDRAC Service Module) installed on the server. You can login to iDRAC and disable "OS to iDRAC Pass-through" feature to disable this NIC. This setting is available in "iDRAC Settings -> Connectivity -> OS to iDRAC Pass-through" page of iDRAC.
