 ERPS¶
 ERPS (Ethernet Ring Protection Switching) - если по-простому, "своими словами", то это протокол L2 уровня, который позволяет создавать резервные пути для прохождения вланов без образование петель. По сути создается два пути по "кольцу" из коммутаторов, при чем один путь является основным, второй резервным.
