The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcSanPcEp:autoNegotiate managed object property", so it carries no real prose -- but the property name and its TruthValue type tell you what it holds: It holds whether speed and duplex auto-negotiation is turned on for this FC SAN port-channel member port's link. When this is true, this FC SAN port-channel member port and the specific SAN switch port that this one bundled member link connects to negotiate their operating speed automatically on link-up; when false, an admin has pinned the speed manually, which is often required for older FC gear that does not negotiate reliably above a certain rate. This typically reads "true" on a modern 16G/32G FC uplink and might be forced to "false" if this FC SAN port-channel member port needs to be locked to a specific legacy speed.
