Total Errors |
|
Total Errors | The total number of errors of any kind processed |
| by the device, board, or port. |
Collisions | The total number of collisions detected by the |
| device, board, or port. |
CRC Errors | The total number of packets with CRC (Cyclical |
| Redundancy Check) detected by the device, |
| board, or port. |
Runt Packets | The number of runt packets detected by the |
| device, board, or port. A runt frame is one that is |
| less than the minimum Ethernet frame size of 64 |
| bytes. |
Giant Packets | The number of giant packets detected by the |
| device, board, or port. A giant frame exceeds the |
| maximum Ethernet frame size of 1518 bytes |
| (excluding the preamble). |
Algn. Errors | The number of misaligned packets detected by |
| the device, board, or port. Misaligned packets |
| are those which contain a |
| of bytes (that is, any unit of bits less than a byte); |
| they can result from a MAC layer packet |
| formation problem, or from a cabling problem |
| that is corrupting or losing data. |
OOW Collns. | The number of collisions out of the standard |
| collision window (51.2 µs) detected by the |
| device, board, or port. There are two conditions |
| which can cause this type of error to occur: either |
| the network’s physical length exceeds IEEE 802.3 |
| specifications, or a node on the net is |
