This read-only object mirrors the `policyLevel` property of a catalog entry describing a supported type of I/O card used inside a Cisco UCS fabric extender or I/O module slot inside Cisco UCS Manager's internal information model, exposed here as a non-negative gauge value for this IOM I/O-card type definition. The policyLevel is a numeric marker in UCS Manager's org-hierarchy policy-resolution model, recording which organizational level's settings were actually applied to this IOM I/O-card type definition. A value of 0 for an entry describing the I/O-card variant fitted to a 2408 fabric extender means the setting came from the root org, while a higher number means a sub-organization's override took precedence.
