This read-create value controls the lifecycle of a row in the link backup interface configuration table, following standard SNMP RowStatus semantics for creating, activating, taking out of service, or deleting entries. An admin must ensure a row is not active(1) before modifying it, and can set notInService(2) to temporarily disable a specific link backup pair's configuration without deleting it. For example, an admin creating a new link backup pair sets hm2LinkBackupRowStatus to createAndGo(4) to instantiate and immediately activate the row after populating the primary and backup interface indices.
