sUNWffbentrysunSmTreeProp is a DisplayString holding the tree-position property string that places the Sun FFB graphics device within the device's internal Sun-style management object tree (the SUNWffb device table). An admin browsing the gateway's hardware inventory through this MIB relies on this property to know where the Sun FFB graphics device sits structurally relative to other components, rather than reading it as a health value itself. For example, a management console rendering a hardware tree view would use sUNWffbentrysunSmTreeProp to draw the Sun FFB graphics device entry nested under its parent chassis/board node rather than as a top-level item.
