The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcZoneProfile:intId managed object property", so it carries no real prose -- but the property name and its SnmpAdminString type tell you what it holds: It holds an internal numeric identifier UCS Manager assigned to this FC zoning profile. Like the id field on a zone, this is the stable internal handle software uses to reference this specific zoning profile even if its admin-facing name is later changed, so cross-references elsewhere in the MIT keep pointing at the right object. This zoning profile might carry intId "20147" as its internal reference number.
