A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented?
(Choose two)

• A.runts
• B.giants
• C.frame
• D.CRC
• E.input errors

Correct Answer: D,E

Explanation
Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the frame and counts it as some kind of input error.
Cisco switches list this error as a CRC error. Cyclic redundancy check (CRC) is a term related to how the FCS math detects an error.
The "input errors" includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts.
The output below show the interface counters with the "show interface s0/0/0" command:
