The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcoeSanEp:locale managed object property", so it carries no real prose -- but the property name and its CucsFabricExternalEpLocale type tell you what it holds: It holds which side of the fabric UCS Manager considers this FCoE SAN uplink port to belong to -- internal (chassis-facing) versus external (uplink-facing). Since an Ethernet uplink port on the fabric interconnect that carries FCoE traffic to an upstream FCoE-capable SAN switch (an FCF), this value should consistently read "external" for this object; UCS Manager uses this classification internally to decide which set of validation and discovery rules apply to it. For this FCoE SAN uplink port the expected value is "external", flagging it as an uplink-side object rather than something facing the chassis backplane.
