Hi upendra,

You can execute the command to check router serial number & all see the below command.

Router#sh invertory

Router#sh hardware

Hi there,

Occasionally, the serial number is listed on "show version" - I have a 1700 series myself, but it's my home router, and I'm at work, so I can't check.

If it's not in "show version", do you have physical access to the router? If not, would you be able to contact someone who does?

Kind regards

HI Upendra,

#show inventory

-->command is applicable to specific IOS and Router Model.

#show version


#show hardware

-->might help you. Neverthless if nothing works then you need to have a Physical access to the Router.

hey upendra,

Router#sh hardware

Router#sh version

try these two commands otherwise go to router and "Router#show ?" it will show all compatable show commands for that particular router model

I prefer to have the serial number configured through SNMP for all the device that do not support the inventory command or report the processor ID when used.

snmp-server chassis-id

once you have this configured, you can fetch the serial number by uisng the sh snmp command
