				 For example:
				 
				 "6"  		indicates that OIDs from this MIB group are to be collected
								only for ethernet interfaces (ifType = 6)
				 "6,22"		indicates that OIDs from this MIB group are to be collected
								only for ethernet and serial interfaces
				 "all" 		indicates that the OIDs from this MIB group are to be
							collected for all interfaces regardless of ifType
				"ignore" 	indicates that OIDs from this MIB group are node-level
							objects
								
				Sample ifType descriptions/values:
