# Dell IL 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.
