Runts are Ethernet packets that are less than 64 bytes and may be caused by excessive collisions.

A high number of CRCs is usually the result of collisions or a station transmitting bad data. On a LAN, this usually indicates noise or transmission problems on the LAN interface or the LAN bus itself.

CRC errors indicate that the cyclic redundancy checksum generated by the originating LAN device does not match the checksum calculated from the data received.

These are explanations of CRC errors and runts: Both sides should be set to auto speed and auto duplex, or hard set to the same speed and duplex settings.

If runts and Cyclic Redundancy Check (CRC) errors are incrementing in the show interface command output, or Frame Check Sequence (FCS) errors and runts are incrementing in the show port command output, check the port speed and duplex settings.Įnsure that both devices are configured identically.
