I am reviewing the QFX5120-32C.
Regarding Port Setting, I have seen a document with the following contents.
====================================================================================================

https://www.juniper.net/documentation/en_US/junos/topics/topic-map/switches-interface-port.html#config-steps
To configure ports 4 through 7 to operate as 25-Gigabit Ethernet ports, you must configure port 4 to operate as 25-Gigabit Ethernet ports.
[edit chassis fpc 0 pic 0]
user@switch# set port 4 speed 25g
====================================================================================================
Q1. Does it mean that 0-3, 4-7, 8-11 ... are operated at the same channelize speed as one port group?
Q2. If so, does the non-channelize port (40G/100G) work regardless of the port group?
I can't find the exact document.
Please Help me.
