 ## Reading Services
 
 When an exported service has been imported to another cluster, you can use the `health` REST API endpoint to query the service on the consumer cluster.

 ## What is Consul Dataplane?
 
 When deployed to virtual machines or bare metal environments, the Consul control plane requires _server agents_ and _client agents_. Server agents maintain the service catalog and service mesh, including its security and consistency, while client agents manage communications between service instances, their sidecar proxies, and the servers. While this model is optimal for applications deployed on virtual machines or bare metal servers, orchestrators such as Kubernetes and ECS have native components that support health checking and service location functions typically provided by the client agent.

+### Namespace ACL permissions
+
+If ACLs are enabled, exported services between partitions that use dataplanes may experience errors when you define namespace partitions with the `*` wildcard. Consul dataplanes use a token with the `builtin/service` policy attached, but this policy does not include access to all namespaces.
+
+Add the following policies to the service token attached to Consul dataplanes to grant Consul access to exported services across all namespaces:
+
+```hcl
+partition "default" {
+  namespace "default" {
+    query_prefix "" {
+      policy = "read"
