The real DESCRIPTION field here is just the auto-generated stub "Cisco UCS fabric:FcSanPcEp:membership managed object property", so it carries no real prose -- but the property name and its CucsFabricMembershipStatus type tell you what it holds: It holds this member port's current membership status within its parent FC port-channel. Because one individual physical FC uplink that has been added as a member link into a larger FC SAN port-channel bundle, this status is what actually determines whether this link is contributing bandwidth to the bundle right now -- a member can be physically up yet still show "waiting" or "down" here if the port-channel protocol has not admitted it into the bundle. A contributing member typically shows membership "up"; one that has not yet been accepted into the channel might show "waiting" or "suspended".
