This read-create RowStatus governs the lifecycle of a conceptual row in the VMPS table, and requires a valid vmpsManagementDomain value before the row can be activated. An administrator uses it when provisioning a new VMPS instance via SNMP, though devices supporting only a single VMPS instance may keep this row permanently instantiated. For example, an attempt to activate a row without first setting vmpsManagementDomain would fail until that value is supplied.
