Electronic Serial Numbers in IOS

[jmathis]

On the 1751 router, "sho inventory" will give you an electronic serial number (i.e. FOC...) for the overall device. This number, however, does not match up to a chassis serial number (i.e.JMX...) electronically. For trying to validate remote serial numbers, is there a way through the software to correlate this electronic serial number to the chassis serial number?

Thanks

AFAIK, the sh inventory command in the old routers like 17xx abd 26xx is a recent addition but they show the processor ID instead of the Chassis serial number

Only the ISR seems to provide the proper serial number with the above command

Its advisable to configure the serial number for these devices using the snmp chassis-id command which can be retreived later using SNMP
