have two Css610-8G-2S, each has a single S+85DLC03D and are linked with a 75m OM5 cable.
After booting the link starts to randomly drop and is never up for more than a minute or two. I have tried to move the SFP module between ports on each switch, no change. When the link is up, it does not pass traffic.
I do not have any other hardware to test with. Any suggestions?
