Hope somebody can help with this problem I have. Basically an optical link (trunk) between 2 switches stops working after about 48 hours. These are  S4128F-ON and N1548P (SFP+ optics on both ends and 20m optical cable, 10G SFP+ port on S4128 and 10G tengig port 1 on N1548P). Re-inserting the optics/cable fixes the problem for a while. All gear is in a remote data center so diagnostics is pretty tricky. We already replaced the cable, guess now should try replacing all other components one by one? Usual suspects in such cases?

Thank you

P.S. Posting to this forum is horrendous. I get 'Correct the highlighted errors and try again.' but nothign is higleghted and preview is fine.
