ℹ️ Info
The Green Port - the leftmost RJ45 on the Cascade Lake CNode (The Green Port) is “reserved” and is not used in a VAST Deployment.
⚠️ 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.
ℹ️ Note
Skip NIC cannot be used with mixed Ethernet + IB configurations.

Cascade Lake CBox with CX5+CX6 NIC in ETH + IB mode with “Reverse NICs” enabled
ℹ️ Info
The “Reverse NICs” flag is a setting that can be set either in the VAST GUI Installer or via the command line
configure_network.pytool. This flag is set on a per-CNode basis.
⚠️ Warning
Since this is a per-CNode setting, it is possible for a chassis to have CNodes with differing configurations. If you are unsure of the configuration of a CNode, please contact VAST Support for assistance.
The “Reverse NICs” flag refers to a specific configuration that swaps the roles between the NIC intended for northband traffic and the NIC intended for internal traffic. This is primarily used in scenarios where the physical cabling or hardware layout necessitates a reversal of these roles.
