Hardware check on C9400

[junrey]

Hi all, 

Good day! 

Hope you are well. I'm trying to find out commands to use to check the C9400 switches if it is still working as it should be.  

I've run show tech command and the result is very long and I don't understand most of it. 

Is there a list of commands I can use for me to check the hardware?  e.g no dead port, ram, cpu, supervisor etc. 

Cheers!

that is for full diagnosis when TAC asked to provide, basic test you can do as per the below document :
