The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcSanPcEp:transport managed object property", so it carries no real prose -- but the property name and its CucsFabricAFcSanEpTransport type tell you what it holds: It holds the underlying transport medium this FC SAN port-channel member port uses to carry its storage traffic. This tells UCS Manager (and anyone polling this OID) whether this particular FC SAN port-channel member port is riding native Fibre Channel or Fibre Channel over Ethernet, which in turn determines which set of speed, framing, and licensing rules apply to it. For FC SAN port-channel member port, transport typically reads "fc" here, matching the storage protocol this object was built to carry.
