The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcZoneProfile:policyLevel managed object property", so it carries no real prose -- but the property name and its Gauge32 type tell you what it holds: It holds the level in the UCS organizational hierarchy at which this FC zoning profile's policy was actually defined. Since UCS Manager lets policies be defined at the root organization or overridden at a sub-organization, this number tells an admin how far down the org tree this specific zoning profile's controlling policy sits, which explains why two profiles under different sub-orgs might behave differently even with the same name. A value of 0 here would mean this zoning profile's policy comes straight from the root org, while a higher number reflects a policy overridden deeper in a sub-organization.
