Description: dot3StatsFCSErrors : A count of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check.

The count represented by an instance of this object is incremented when the frameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

What is snPOSStatsFCSErrors?

Counts received frames that are a whole number of octets in length but still fail the frame check sequence (dot3StatsFCSErrors equivalent). Rising values here usually indicate noise or signal degradation on the SONET/SDH circuit.
