Why would you do that?Hello, I have a question regarding the implementation of web server based applications. Is that possible to configure RPi CM4 Ethernet at 100 Mbps instead of 1000 Mbps ?
Place a 1000MBps jack on your carrier as outlined in the CM4IO/CM5IO schematics. Period.
If you connect a slower device the Pi's PHY should be able to autonegotiate. You can test this with a standard Pi 4/5 and an 100 MBps switch.
