What is juniSlepLinkStatusBadFCSs?

This read-only Counter32 tallies the number of frame check sequence (FCS) errors seen on this SLEP link entity, meaning frames received with a checksum mismatch indicating corruption in transit. An admin watches this counter to catch cabling, connector, or duplex-mismatch problems on the link, since a rising rate of FCS errors points to physical-layer trouble rather than a software issue. For example, if the counter climbs from 0 to several thousand over an hour on a given link, that link's cable or transceiver should be inspected and possibly replaced.
