How to Authenticate SSH/Telnet Users Via RADIUS

We have around 58 MA5603T OLT’s in our networks. We want telnet/ssh authentication to be done via Radius.
Can you please support us in providing correct configuration to authenticate telnet/ssh users via radius?

Currently I’m trying to integrate my LAB OLT to radius.

Device Type             = MA5603T Device
Device Version          = MA5600V800R016C00


Configuration in live network：
