 In a cluster using a Kubernetes Container Network Interface (CNI) plug-in that supports Kubernetes network policy, network isolation is controlled entirely by `NetworkPolicy` objects.
 In {product-title} {product-version}, OpenShift SDN supports using network policy in its default network isolation mode.
 
-[NOTE]
-====
-When using the OpenShift SDN cluster network provider, the following limitations apply regarding network policies:
-
-* Egress network policy as specified by the `egress` field is not supported.
-* IPBlock is supported by network policy, but without support for `except` clauses. If you create a policy with an IPBlock section that includes an `except` clause, the SDN pods log warnings and the entire IPBlock section of that policy is ignored.

 [WARNING]
 ====
 Network policy does not apply to the host network namespace. Pods with host networking enabled are unaffected by network policy rules.
