Set the Default CNI for Tanzu Kubernetes Grid Clusters

As a vSphere administrator, you can set the default container network interface (CNI) for Tanzu Kubernetes clusters.

Default CNI

Tanzu Kubernetes Grid supports two CNI options for Tanzu Kubernetes Grid clusters: Antrea and Calico.

The system-defined default CNI is Antrea. For more information on the default CNI setting, see Using TKG Service with vSphere IaaS Control Plane.

You can change the default CNI by using the vSphere Client. To set the default CNI, complete the following procedure.
