Ethernet Ring protection switching

 (

ERPS

) is a link layer protocol applied on Ethernet loop protection to 

provide sub-50ms protection and recovery switching for Ethernet traffic in a ring topology. 

 

ERPS provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or RSTP, but the 

algorithms between them are not the same. In the Ring topology, every switch should be enabled with Ring function and two 

ports should be assigned as the member ports in the ERPS. Only one switch in the Ring group would be set as the RPL owner 

switch that one port would be blocked, called 

owner port

, and PRL neighbor switch has one port that one port would be blocked, 

called 

neighbor port

 that connect to owner port directly and this link is called the 

Ring Protection Link

 or 

RPL

. Each switch 

will sends ETH-CCM message to check the link status in the ring group. When the failure of network connection occurs, the 

nodes block the failed link and report the signal failure message, the RPL owner switch will automatically unblocks the PRL to 

recover from the failure.
