Hi Guys

Does anyone know the definition/output of NX-OS command “show hardware internal carmel crc”?

The output is eight column table, like below. I can’t find explanation of the column names like MM tx CRC etc.
I know about Tx Rx and CRC, but not the FI and MM.

+----------+------------+------------+------------+------------+------------+------------+------------+
|   Port   | MM rx CRC  | MM Rx Stomp| FI rx CRC  | FI Rx Stomp| FI tx CRC  | FI tx Stomp| MM tx CRC  |
+----------+------------+------------+------------+------------+------------+------------+------------+
| Eth 1/1  |        --- |        --- |        --- |        --- |        --- |       1740 |       1740 |
| Eth 1/2  |        --- |          2 |        --- |          2 |        --- |        168 |        168 |
| Eth 1/3  |        --- |        --- |        --- |        --- |        --- |          2 |          2 |

| Eth 1/8  |        --- |        --- |        --- |        --- |        --- |       1439 |       1439 |
| Eth 1/9  |        --- |        --- |        --- |        --- |        --- |        --- |        --- |
| Eth 1/10 |     472005 |        --- |        --- |     467858 |        --- |        164 |        164 |

I’m troubleshooting interface errors on Nexus 5000, probably caused by MTU violation.

TIA
