Product Specifications
InDiscards | Total valid frames received that are discarded due to lack of | |
| buffer space. This includes frames discarded at ingress as well as | |
| those dropped due to priority and congestion considerations at | |
| the output queues. Frames dropped at egress due to excessive | |
| collisions are not included but are counted in the Excessive | |
| counter. |
|
InFiltered | If 802.1Q is disabled on the port, these are the total valid frames | |
| received that are not forwarded to a destination port. These are | |
| frames for which the destination port vector is 0 or are not | |
| forwarded due to the state of the portState bits. valid frames | |
| discarded due to a lack of buffer space are not included. | |
| If 802.1Q is enabled on the port, then these are the total valid | |
| frames received (tagged or untagged) that were discarded due | |
| to an unknown VID (i.e., the frame's VID was not in the VTU) | |
OutUnicasts | Total valid frames transmitted with a unicast destination | |
| address |
|
OutBroadcasts | Total valid frames transmitted with destination address equal to | |
| FF:FF:FF:FF:FF:FF. |
|
OutPause | Total pause frames transmitted. |
|
OutMulticasts | Total valid frames transmitted with multicast destination | |
| address that are not counted in OutBroadcasts or OutPause. | |
OutFCSErr | Total frames transmitted with a valid length and an invalid FCS. | |
OutGoodOctets | Total data octets transmitted. The count includes the FCS but | |
| not the preamble. |
|
Out64Octets | Total frames transmitted with a length | of exactly 64 octets, |
| including those with errors. |
|
Out127Octets | Total frames transmitted with a length | of between 65 and 127 |
| octets inclusive, including those with errors. | |
Out255Octets | Total frames transmitted with a length | of between 128 and |
| 255 octets inclusive, including those with errors. | |
Out511Octets | Total frames transmitted with a length | of between 256 and |
| 511 octets inclusive, including those with errors. | |
Out1023Octets | Total frames transmitted with a length | of between 512 and |
| 1023 octets inclusive, including those with errors. | |
OutMaxOctets | Total frames transmitted with a length of between 1024 and | |
| 1522 octets inclusive, including those with errors. | |
Collisions | Total number of collisions during frame transmission. | |
Late | Total number of times collision is detected later than 512 bit- | |
| times into the transmission of a frame. |
|
Excessive | Total number of frames not transmitted because the frame | |
| experienced 16 transmission attempts and was discarded. The | |
| discard will only occur if DiscardExcessive is set to a 1 (in global | |
| control register). |
|
Multiple | Total number of successfully transmitted frames that | |
| experienced more than on collision. |
