Unreg |
| Numberof 802.3 frames received and discarded because the destination |

EthUnreg |
| Number of Ethernet frames received and discarded because the destination |
|
| Protocol was not configured in the node.. |
MacErr |
| A severe network fault prevented transmission of a frame for more than one |
|
| second. See Exception Log, Event c, Entry 2 = 10b. |
BufProb |
