Serial Numbers for IOS and CatOS

What does Cisco recommend to use for asset inventory tracking purposes? Do they recommend using the Processor ID or the Chassis serial number? I'm curious because we just had a call and it was said that Cisco recommends using the Processor ID (you can find the ID when doing a 'sh ver'). I thought it would be wise to use the Chassis Serial # --- this can't be changed right? The processor ID and the Serial # are two different #s I think. A person on the call said that in their 6500s, the Processor ID and the chassis Serial # (on the backs-left of chassis) is the same -- how is this possisble?

I'm confused. Can someone help?

Thanks in advance.

Processor ID and system serial number is same. Its the Processor Id and Motherboard serial number which differs.

I am having a similiar question / problem. We are trying to clearup our smart net agreements and we are using the serial number as a guide. The "external" serial numbers are different from the "show version" serial numbers, on our VG248 devices?

EXTERNAL SERIAL NUMBER=SAD093301VT

SHOW VERSION=
