Same problem over here with CRS328-4C-20S-4S+RM on Sfp+ ports. I'm connected to a Dell X1052 with S+DA0003.
Let's wait for the correction.
I have a CCR1036-8G-2S+ on another 10G port on that same switch and nothing happens, including using the same type of cable.Just thinking, I have a CRS326, up time currently reported as 51d12h, have zero downtime / flaps on SFP+ port.
Are the flaps not maybe caused by the other side?
