Description
This article describes a use case for trying to change the link speed for one port which is a part of quad group.
Scope
FortiGate.
Solution
- Edited port25 and received the below warning as speed will be changed for other ports.
utm (port25) # set speed 25000full
utm (port25) # next
The speed/mediatype/FEC of port25/port26/port27/port28 will be changed from 10000full/sr/disable to 25000full/sr/cl91-rs-fec.
Do you want to continue? (y/n)n

It is possible to run the command 'get hardware npu np6 port-list' and check if these ports are part of quad group.
If it is a part of the quad group, the speed cannot be changed and it is not possible to split the ports separately from the port group members as it comes by design.
utm # get hardware npu np6 port-list
