Packets In Error | Displays the number of error packets coming into the interface.It includes: |
| • Runt frames — Packets shorter than the minimum Ethernet frame length (64 bytes). |
| • CRC errors — The Cyclical Redundancy Check (CRC) is the 4 byte field at the end of every |
| frame the receiving station uses to interpret if the frame is valid. If CRC value computed |
| by the interface does not match with the value at the end of frame it is considered as a |
| CRC error. |
| • Late collisions — A late collision is any collision that occurs after the first 64 octets of |
| data have been sent by the sending station. |
| Late collisions are not normal and are usually the result of out of spec. cabling or a |
| malfunctioning device. |
| • Misaligned frames — A misaligned frame is a frame that somehow gets out of sync with |
| the receiving station’s receive clock recovery circuit. Misalignment is reported if the |
| frame ends with a CRC error and extra bits are also detected. |
Bytes Out | Displays the number of bytes going out on the interface. |
Packets Out | Displays the number of packets going out of the interface. |
Packets Out Dropped | Displays the number of dropped packets going out of the interface, due to the saturated |
| output queues assigned to the interface processor or the physical device/software module. |
| Packets can be dropped due to collisions as well. |
Packets Out Error | Displays the number of error packets going out of the interface, including frame forming |
| errors or malformed packets transmitted over the interface. |
