The MIB's DESCRIPTION for cucsLsRequirementQualifier is only the auto-generated stub 'Cisco UCS ls:Requirement:qualifier managed object property', but the 'qualifier' property name together with its SnmpAdminString type tell us this column, on a service profile's server-pool requirement (the qualifier UCS Manager uses to auto-pick a blade from a pool), holds the qualifier as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The qualifier is the actual filtering criteria (CPU, memory, adapter type, etc.) this requirement applies when selecting a server from the pool, i.e. the rule that decides which pool members are eligible for this specific profile. A qualifier demanding a minimum of two CPU sockets would exclude single-socket blades from being auto-assigned to this profile even if they're in the pool.
