Good morning

I am working to enable 100Gig interface on our MX204.    I have found community documentation online referencing the commands below and then offline and online commands.   I keep getting an error message after offline /online about invalid pic/port config.  I am looking to see if anyone else has run into this or has additional recommendations.  Thank you in advance!

Unfortunately, I keep getting an error message.

You need to disable 10G ports to use 100G ports as you can see in this document (table 3):

https://www.juniper.net/documentation/us/en/software/junos/interfaces-ethernet/topics/topic-map/port-speed-mx-routers.html

When you configure new port schema you need to restart fcp 0 (service impacted)

Thank you to everyone for the assistance the configuration references.  It appears I created my issue, by only configuring ports 0 and 1 of PIC 0. 

All of the shared configuration examples showed both PICs and ports configured.  Once we switched to configuring all ports the error cleared. 

I also found this line in the document shared by Francisco:  

On an MX204 router, there are two line card- MIC (PIC1) and fixed-port PIC (PIC0). You must configure both the PICs and all the associated ports, under the [edit chassis] hierarchy. Configuring ports on only one of the PICs results in an invalid configuration.

Here is a config for 3x100G + 8x10G combination:

set chassis fpc 0 pic 0 port 0 speed 100g
set chassis fpc 0 pic 0 port 1 speed 100g
set chassis fpc 0 pic 0 port 2 speed 100g
set chassis fpc 0 pic 1 port 0 speed 10g
set chassis fpc 0 pic 1 port 1 speed 10g
set chassis fpc 0 pic 1 port 2 speed 10g
set chassis fpc 0 pic 1 port 3 speed 10g
set chassis fpc 0 pic 1 port 4 speed 10g
set chassis fpc 0 pic 1 port 5 speed 10g
set chassis fpc 0 pic 1 port 6 speed 10g
set chassis fpc 0 pic 1 port 7 speed 10g
set interfaces et-0/0/3 disable

The command "unused" is unsupported on MX204, so a port can't be disabled under "chassis" configuration, and if it's not disabled, then it takes default settings no matter what, causing invalid combination.
