Ethernet Ring Protection Switch (ERPS) is an Ethernet ring protection protocol which is
used to prevent forming the loop in LAN, thus, the Broadcast Storm problem could be
avoided. The loop avoidance mechanism ensures the traffic flows on all but the RPL ring
link. In order to achieve the loop-avoidance mechanism, ITU-T G.8032 defines three
roles in ERPS, which are “RPL Owner Node”, “RPL Neighbor Node”, and “Normal Node”.
Below are two scenarios describing how to configure the ERPS in Antaira’s industrial
managed Ethernet switches. Users can reference it to configure the managed switch as
RPL-configured architecture shown in Figure 5.24 or Non-configure architecture shown
in Figure 5.25.
