Hoping that someone can point me in a direction please?

I am having some issues with being able to use the VIC 1457 on my proxmox build (current at 9.2.3 but installed about a year ago and I think it was 8.7.X

For the original installation I used only the 2 x onboard interfaces and they work just fine, however I am now trying to bring up a 10G connection over fiber on the VIC 1457 MLOM card.

The interfaces do show up in the proxmox interface and I do see link on my Catalyst 2960X switch, however cannot ping the interface. I have gone through the CIMC and turned off all kinds of bits and currently have them in 'physical NIC mode'

I have also turned off the FEC and have changed the VLAN mode to Access...

I create a bridge interface and use one of the NIC interfaces, but cannot ping the IP on the bridge

Interestingly, what I see on switch versus on the Proxmox CLI shows a different MAC...

and

Thus the MAC/interface that proxmox and the CIMC show is not what is showing up on my switch..

Any ideas? what am I missing?

Thanks, Jeff
