This TruthValue flags whether this particular live FCoE interface stats sample is considered unreliable — for instance because it was collected during a state transition, a counter reset, or a gap in polling. Admins should treat the accompanying counters on this FCoE interface object with caution whenever this flag reads true(1), since a spike recorded in the same sample could be an artifact of the collection glitch rather than real traffic or errors. For example, this would flip to true(1) briefly right after the adapter reinitializes following a firmware upgrade or link flap, then return to false(2) once clean sampling resumes.
