The MIB's DESCRIPTION for cucsLicenseSourceFileQuant is only the auto-generated stub 'Cisco UCS license:SourceFile:quant managed object property', but the 'quant' property name together with its Gauge32 type tell us this column, on one individual license file entry recorded under a license source, holds the quant as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The quant is the quantity of the licensed feature this specific file entry grants, which UCS Manager sums across all installed files to arrive at the total absQuant seen on the license instance. A file granting 4 additional ports would show quant 4 here, adding to whatever quantity other installed files already contributed.
