I can’t get 10G connection between RB4011iGS+ and CRS312-4C+8XG-RM, any idea what could be the problem?
You do not provide any relevant detail for at least “guessing”
It’s the frog, it’s always the frog!
The RB4011 doesn’t seem to advertise 10G at all, any idea?


You’re using ether1. It’s a gigabit port, use the sfp+ cage
