The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcSanPc:operState managed object property", so it carries no real prose -- but the property name and its CucsNetworkPortOperState type tell you what it holds: It holds the actual, currently-observed operational state of this FC SAN port-channel, as opposed to what an admin asked for. Because this reflects reality rather than intent, this is the value an admin watches to know whether this FC SAN port-channel is really passing traffic -- it can read down even when adminState says enabled, which is the signature of an actual fault such as a bad SFP or a disconnected cable. For instance operState might show "up" during normal operation and flip to "failed" or "link-down" the moment the SAN-side cable on this FC SAN port-channel is unplugged.
