The topic/title/post we're on right now is the thread that had a comment mentioning the SFP (post #7 by JunoBox on 10/13/21). I'm guessing we're using different terminology to refer to forum posts/threads/topics/followups.

Saw another post on this thread mentioning SFP ports having the same issue and thought it was OK to bring it up (thread title didn't limit the issue to QSFP+ only). Glad to hear the issue is resolved for the CRS326-24S+2Q+RM with QSFP+ ports in 2.16. Sad that the issue still remains for others.

SwOS 2.16 was released and it still seems to have the same problem. Tested on a CRS309-1G-8S+. Only thing I didn't do was removing power to the device after the upgrade to see if that changes anything.
