Just installed ESXi 6.5 U1 on a C240 M5 with a VIC 1457 mLOM in it and ESXi is only seeing 2 of the 4 ports. Furthermore, they're showing as down even though they're connected to known active ports. I can't find anywhere in the BIOS to make any configuration changes to the VIC. What am I missing? We have 3 of these servers and they're all doing the same thing.
Can you confirm the adapter settings from the CIMC? Do you have "port-channel mode" checked?
Did you install ESXi using Cisco custom ISO with correct drivers? Do you have link light on the interfaces that you expect to be up?
Well, 50% of the way there. I now see the 4 vNICs, but they're all showing as link down. The ports on the switch are enabled & configured, so not sure if I'm missing another setting somewhere.
How is the VIC connected to the upstream switches? Does port 1 and 2 go to one switch and 3 and 4 go to the other?
This document outlines supported connectivity for VIC 1455 and VIC 1457. Page 28-29
What is the config on the switchports that you are connecting the VIC to?
Ports 1 & 2 go to port 31 on a switch pair and ports 3 & 4 go to port 31 on another switch pair. So technically, each port on the VIC is going to a different switch. No link aggregation is configured on the switch ports.
Got it. What is the config on the switch ports? Are you trying to port-channel the links from the switch side down to the VIC?
Apparently the issue is actually bug. If you leave the FEC mode to the default "auto" setting, the link will not negotiate. If you define the setting as cl74, the links come right up. Apparently this issue is only for the vic 1457 in a C240 M5.
