I was asked to find the serial numbers for the routers at my company (which are all different models and IOS).
What is the one command to see what the routers serial number is similar to how you see it on the switches.
I tried the show diag command but it spits back like 2-3 different serial numbers and not sure which one is the actual whole routers serial number. Is it the PCB serial number or chassis serial number etc? or something else? I hope i dont have the physically go to the router to do this.
Please can someone help me on this.
