Jumbo Frame in same location

[nbctcp]

HW INFO:
-Fortigate 60F
-Switch ICX7150
-Ruckus AP WIFI6

If all those in same location

?
1. Do I need to enable Jumbo Frame 
-on AP, SWITCH and FIREWALL

2. SWITCH SIDE
if yes then is jumbo only in the port that AP connected or all ports

I am asking this because this link said so
https://higherlogicdownload.s3.amazonaws.com/HPE/MigratedAttachments2/D536B1B7-758C-4B2B-8C67-F355C2...

I don't know whether that link all in the same location or doing GRE tunneling between HQ and BRANCH

Based on that document, it sounds like you need to enable jumbo in the whole network. For ICX, It is a global config and is enabled switch-wide:

conf t

jumbo

[nbctcp]

when I ask the same in Aruba forum
https://community.arubanetworks.com/discussion/jumbo-frame#bm88e809b7-6ca9-4774-a71e-888e27791fd5
he said jumbo frame only needed when in Branch site need to tunneled back to HQ
but then we can't set jumbo in ISP site
?
1. If the function is there but can't be used in real life
Then what for the function created
2. In your experience
Do you enable Jumbo in local LAN between firewall as gateway, switches, WLC, AP
