What is usdSlepLinkStatusBadFCSs?

This Counter32 counts the number of frame check sequence (FCS/CRC) errors detected on this SLEP interface. An admin monitors this as a standard indicator of physical-layer link quality problems, such as bad cabling or a faulty transceiver, on the underlying link the SLEP interface rides on. A rapidly climbing FCS error count points the admin toward a physical-layer issue on the interface identified by usdSlepIfLowerIfIndex.
