This TruthValue flags whether UCS Manager considers the accompanying receive counters unreliable for this collection interval, for example after a counter rollover, a device reboot, or a gap in polling. It matters on the live receive-side counter set UCS Manager keeps for one Ethernet endpoint (a blade's vNIC adapter port, an I/O Module uplink, or a fabric-interconnect server port) inside a UCS domain because a monitoring tool that graphs raw byte/packet deltas without checking this flag can show a false spike or a false drop right after a counter reset. When suspect is true(1), an admin should discard that single sample rather than alert on it, e.g. a one-time reading of 4,294,967,295 bytes caused by a 32-bit counter wrap rather than real traffic.
