So we have 2 QFX-5100-48s switches.
We plugged a certified compatible 10GB optic into a port 46 on switch 1. It didnt light up. We figure, bad optic. We plug another known good optic into the same port. Doesnt work. Take this same known good optic, plug it into the port next door, works. Take it out, plug the first optic into the new port, doesnt work. Plug the known good one into this same new port, doesnt work.
Its almost like this first optic breaks ports ? This cant be true right ? I reboot the cluster, the condition persists. I have a case open.
Any thoughts ? Thanks.
