About the supported features
In the following tables, any feature with a check mark in a Supported column indicates that the feature is fully supported by Google Cloud Support. Features not explicitly listed in the tables receive best-effort support.
Supported default indicates a feature that is enabled by default when you install Anthos Service Mesh.
Supported optional indicates a feature that you can optionally enable when you install Anthos Service Mesh. For information on enabling a Supported optional feature, see Enabling optional features.
Not supported indicates that the feature is not supported in Anthos Service Mesh.
