+# hrui_port_isolation (Resource)
+
+
+
+## Example Usage
+
+```terraform
+resource "hrui_port_isolation" "example" {
+  port           = "Port 1"
+  isolation_list = ["Port 2", "Port 3"]
+}
+```
+
+<!-- schema generated by tfplugindocs -->
+## Schema
+
+### Required
+
+- `isolation_list` (List of String) List of isolated ports for the specified port.
+- `port` (String) The port name for which isolation will be configured. Acts as an implicit identifier.
