A G.8032 misconfiguration detection method in a node includes receiving a mapped configuration from another node on a ring, wherein the mapped configuration includes a mapping of G.8032 instances to Virtual Local Area Network (VLAN) identifiers configured at the another node; comparing the mapped configuration with a local configuration on the node; and, responsive to a mismatch in the comparing, providing one of a trap and a notification based on the mismatch. The G.8032 misconfiguration can include one of a VLAN not mapped as protected to a node and a VLAN removed from a protected list at the node.
