An entry in the igControlChannelTable which AUGMENTs the base table interfaceGroupTable. There is a 1-to-1 correspondence between rows in interfaceGroupTable and rows in this table. When a row is created in the base table interfaceGroupTable, the corresponding row in the augmenting table igControlChannelTable must also be simultaneously created. A row in this table is created by setting the value of igRowStatus to 'CreateAndGo' and setting the appropriate values for the columns. Likewise, when a row expires by setting the value of igRowStatus to 'destroy' in the interfaceGroupTable base table, the same row also expires in this augmenting table.
