+# Scope
+
+This document references requirements and provide the usages for managing an OCP Ethernet Switch.
+
+# Requirements
+
+As a Redfish-based interface, the required Redfish interface model
+elements are specified in a profile document. For the Ethernet Switch Hardware Management API v1.0.0, the profile is located at –
+
+```
+https://github.com/opencomputeproject/HWMgmt-OCP-Profiles/blob/master/OCPESwitchHardwareManagement.v1_0_0.json
+```
+
+The Redfish Interop Validator is an open-source conformance test which
+reads the profile, executes the tests against an implementation and
+generates a test report – in text or HTML format.
+
+```
+$> python3 RedfishInteropValidator.py profileName --ip host:port
+```
+
+The Redfish Interop Validator is located at
+<https://github.com/DMTF/Redfish-Interop-Validator>.
+
+The Switch Management v1.0.0 profile extends from the Baseline Hardware
+Management v1.0.1 profile. Conformance to the switch profile requires conformance to the Baseline profile. This extension is specified in the switch profile:
+
+```
+"RequiredProfiles": {
+	"OCPBaselineHardwareManagement": {
+		"MinVersion": "1.0.1"
+	}
+}
+```
+
+# Manageability Tasks
+
+The manageability tasks supported on an Ethernet switch is extended from OCP's common baseline management tasks.
+
+OCP's common baseline manageability task is specified in the "Usage Guide and Requirements for the OCP Baseline Hardware Management Profile v1.0.1" document.
+The following table lists the manageability tasks prescribed by that document.
+
+| **Use Case**          | **Manageability Task**   | **Requirement** |
