This RowStatus object for an entry in the lecsAtmAddrConfigTable cannot be set to active until lecsAtmAddrConfigElanName has an appropriate value, though the agent may supply that value automatically from the parent table's default ELAN name if one is configured. An admin cares because, like the MAC-based table, this lets an ATM-address mapping row activate by inheriting a default rather than requiring an explicit ELAN name every time. For example, an address-range entry created without an explicit ELAN name will still activate if lecsConfigTblDefaultElanName is already set for its parent config table.
