# SMC Gen5 Genoa Port Diagrams - Mixed Ethernet + InfiniBand

> [!WARNING]
> ⚠️ Warning
> 
> Networking is configured on a per-CNode basis, it is possible for a chassis to have CNodes with differing configurations. If you are unsure of the configuration of a particular CNode, please contact VAST Support for assistance.

> [!NOTE]
> ℹ️ Note
> 
> Skip NIC cannot be used with mixed Ethernet + IB configurations.

| 7 | BMC | Dedicated BMC port | (*IPMI) |  |
| 8 | enp65s0f0 | 1 GbE Port 1 (Left) | MGMT/IPMI |  |
| 9 | enp65s0f1 | 1 GbE Port 2 | (*MGMT) |  |
| 10 | enp65s0f3 | 1 GbE Port 4 (Right) | TECH |  |

*In B2B IPMI configuration, the MGMT port is moved to 1GbE port 2 (enp65s0f1), and Port 1 (enp65s0f0) is connected to the Dedicated BMC Port of the Peer Node
