ℹ️ Info
The Green Port - the leftmost RJ45 on the Dell IceLake 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.

Dell IceLake CBox with Dual CX6 NIC in IB mode with “Skip NIC - External” enabled
ℹ️ Info
The “Skip NIC - External” 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.
When this flag is used, VAST instructs the auto-ports feature to disable the NIC that is typically designated for northbound traffic. This means that if you use this flag on a node with two NICs, the NIC designated for internal traffic will handle both internal and external (aka Unified) network traffic. This means the network interfaces that would typically be solely used for northbound connections are effectively disabled. This flag is not valid on a single NIC CNode.
