This RowStatus object cannot move to active until an appropriate value exists for lecsMacConfigElanName, though the MIB notes the agent may auto-populate that value from lecsConfigTblDefaultElanName if one exists for the parent config table. An admin cares because this means a MAC mapping entry can become usable automatically by inheriting the table's default ELAN, not just by explicit configuration. For example, creating a MAC entry without setting an ELAN name explicitly will still activate successfully if the parent lecsConfigTblName already has a default ELAN configured.
