CRS312 - port allows no connectivity

Mon Apr 11, 2022 2:49 pm

HI,
I have a problem with my CRS312-4C+8XG running in SWOS(latest release).
It seems that the switch is completely block network connectivity from time to time, the Port is still active but it's not able to communicate...only after I disable and enable that port again a proper comunication is possible.

It seems that it happens when I send a huge amount of data through that port for a long period of time.

Unfortunatly it does not seem that there is some advanced logging or something like that in SWOS to see what really happens or why...

Actually I read in some other thread that it might has something to do with some MTU size. But I don't think that this is my issue too... can now reproduce that issue without actually transfering data over that port, only initiating some data to transfer is sufficient to "disable" that port. And in the "Error" stats of the switch are no RX/TX Pause or other errors getting listed although the port was just shutdown.

Has anybody some experience on how to troubleshoot that?

Thanks.
