I am doing an inventory of all of our switches and I was wondering if there's a Cisco IOS command that will return the serial number for a switch and router?

Thanks in advance!

    show version should do it for you. You can also try show inventory but that command isn't universally supported. – joeqwerty Jan 20 '15 at 23:11

Sure, that info's usually in the output of show version , though that might vary with specific devices and software versions.


Some Cisco products (ranging from their SMB line to big-boy ASRs) use "show inventory" for displaying pertinent module and Serial Number information.


I'd recommend you to install observium server and via SNMP you can monitor and archive all information in real time.
