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 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? -Adam *Adam Thompson* Consultant, Infrastructure Services [image: MERLIN] 100 - 135 Innovation Drive Winnipeg, MB R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) https://www.merlin.mb.ca Chat with me on Teams <https://teams.microsoft.com/l/chat/0/0?users=athompson () merlin mb ca>
