The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcoeSanEp:fcoeState 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 operational state of the FCoE portion specifically of this FCoE SAN uplink port's link, layered on top of the underlying Ethernet link state. An Ethernet link can be physically up while FCoE itself has failed to establish (for example because FIP snooping or the FCoE VLAN negotiation failed), so this field on this FCoE SAN uplink port is what actually tells an admin whether storage traffic can flow, as opposed to just whether the cable is connected. This FCoE SAN uplink port might show its Ethernet link operationally up while fcoeState reads "down" if FCoE session establishment on top of it has not completed.
