The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcSanPc:transport managed object property", so it carries no real prose -- but the property name and its CucsFabricFcSanPcTransport type tell you what it holds: It holds the underlying transport medium this FC SAN port-channel uses to carry its storage traffic. This tells UCS Manager (and anyone polling this OID) whether this particular FC SAN port-channel 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, transport typically reads "fc" here, matching the storage protocol this object was built to carry.
