Error Type

Description

Input Errors

Total number of errors. It includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts.

Runts

Packets that are discarded because they are smaller than the minimum packet size for the medium. For instance, any Ethernet packet that is less than 64 bytes is considered a runt.

Giants

Packets that are discarded because they exceed the maximum packet size for the medium. For example, any Ethernet packet that is greater than 1,518 bytes is considered a giant.

CRC

CRC errors are generated when the calculated

checksum does not match received checksum

Output Errors

Sum of all errors that prevented the final

transmission from the interface being examined

Collisions

Transmissions due to Ethernet collisions

Late Collisions

Collision that occurs after 512 bits of the

frame have been transmitted
