To use this feature, you (or your cluster administrator) will need to enable the `SCTPSupport` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) for the API server with `--feature-gates=SCTPSupport=true,…`.
As a beta feature, this is enabled by default. To disable SCTP at a cluster level, you (or your cluster administrator) will need to disable the `SCTPSupport` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) for the API server with `--feature-gates=SCTPSupport=false,…`.
When the feature gate is enabled, you can set the `protocol` field of a NetworkPolicy to `SCTP`.

### SCTP
{{< feature-state for_k8s_version="v1.12" state="alpha" >}}
{{< feature-state for_k8s_version="v1.19" state="beta" >}}
Kubernetes supports SCTP as a `protocol` value in Service, Endpoint, NetworkPolicy and Pod definitions as an alpha feature. To enable this feature, the cluster administrator needs to enable the `SCTPSupport` feature gate on the apiserver, for example, `--feature-gates=SCTPSupport=true,…`.
