The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcUserZone:id 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 numeric identifier UCS Manager assigned to this SAN user zone. Because zone names can be edited, this numeric id is the stable internal handle UCS Manager and any integrated tooling actually use to track this specific zone across renames, distinguishing it from every other zone configured in the same zoning profile. This zone might carry id 10025 internally, even though the admin-facing name shown elsewhere is something more descriptive.
