The svcIfSapCfgTable contains objects to configure
(internal) SAP parameters for applicable group interfaces.
Conceptual rows in this table are created and destroyed by the system.
The system automatically creates a row in this table for each
applicable row in the TIMETRA-SERV-MIB::iesIfTable;
currently, applicable rows have the value of iesIfType
is equal to 'group' and the value of
iesIfGroupInterfaceType is equal to 'lns' or 'softGre'.
Deletion of such a row in the iesIfTable results in the same fate
for the corresponding row in this table.
