The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcoeSanEp:operEthLinkProfileName managed object property", so it carries no real prose -- but the property name and its SnmpAdminString type tell you what it holds: It holds the name of the Ethernet link profile that is actually active on this FCoE SAN uplink port right now, as opposed to the one configured. If a profile was recently reassigned to this FCoE SAN uplink port but the change has not yet taken effect, this field can briefly lag ethLinkProfileName -- comparing the two is how an admin confirms a flow-control policy change has actually been applied to the hardware. Immediately after reassigning a profile, this FCoE SAN uplink port might still show the old value here until the fabric interconnect finishes applying it.
