This RowStatus object governs the lifecycle of a row in the per-interface LDP table, and the description notes a row cannot be modified while its value is 'active'. An admin uses it to create, activate, or destroy an interface's LDP configuration row, and must first move it out of active state to change other LDP settings on that interface. For example, an admin sets this to notInService(2) before adjusting h3cMplsExtLdpCapability, then back to active(1) once done.
