Hello,

Do the S32K148 ENET transmit and receive statistics registers overflow and restart from 0, or freeze when saturated to max value?

Kind regards,

Jakub

Hello Jakub,

I tested it today and the counters overflow and start counting from 0 again.

You can refer to RTC2819, historyControlInterval OBJECT-TYPE

https://tools.ietf.org/html/rfc2819

 

Best regards,

Daniel

Hello Jakub,

No, they can be cleared in ENET_MIBC[MIB_CLEAR].

Hello Daniel,

One more question: do the counters clear on read?
