Use this command to associate or disassociate a CFM UP MEP group for subring protection across the main ring.
When an UP MEP is configured for protection of a subring, the Manual Switch event will be enforced on the subring port on the interconnected nodes.As per Appendix X of the standard, the MS is issued when the node type and the multiple failure type are the same. ExtremeXOS implementation currentlyconfigures the node type to be the same as the fault type. So the user will notice both the subring ports of the two interconnected nodes to be held inMS when multiple failures on the main ring occur. When the multiple failure clears this MS is also cleared.
The following command associates a CFM UP MEP group for subring protection on the group "group1":
configure erps ring1 cfm protection add group1
This command was first available in ExtremeXOS 15.3.
