If additional ports are more important than the full 100G throughput, you can configure it as 2x100+2x40+8x10. We tend to break out 10G ports on switches, so we can more fully utilize the 100G ports. My hope for a successor (MX205 ?) would be more flexibility and 25G ports. 4x100G+8x25G would be awesome. thanks, -Randy -- Randy Carpenter Vice President - IT Services First Network Group, Inc.

Adam,
Simply put - No there isn't a way to oversubscribe the front panel.
Juniper has a handy tool to check your port combinations though - [ https://apps.juniper.net/home/port-checker/index.html | https://apps.juniper.net/home/port-checker/index.html ]
The lack of being able to oversubscribe has to do with # of lanes to the EA ASIC, and how those can be broken down.

Hi all,
Hoping some Juniper-using folks know:
On the MX204, which comes with 4x100G + 8x10G ports, you can only use 3 of the 4 100G ports if you want to use any of the 10G ports at all.
Supposedly this is to prevent oversubscription on what is a 400G-rated router. However, I’m perfectly fine with oversubscription with a 400G aggregate throughput cap.
Is there a way to stop the automatic “oh, I’ll disable these other ports for you so you don’t oversubscribe the box” behaviour and let all the front-panel ports be used at once?
