The MIB's DESCRIPTION for cucsLicenseSourceAlwaysUse is only the auto-generated stub 'Cisco UCS license:Source:alwaysUse managed object property', but the 'alwaysUse' property name together with its TruthValue type tell us this column, on the license source configuration UCS Manager consults for a fabric interconnect's license server, holds the alwaysUse as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The alwaysUse TruthValue controls whether UCS Manager should always pull licenses from this particular source (versus only falling back to it if a preferred source is unavailable), a policy switch rather than a status report. Setting this true on a specific license source forces UCS Manager to check that source first for every license lookup, even if another source is also configured.
