Yes it has one but you need physical access to see it :-)

Unfortunately the 2600 series do not report the chassis serial number with any command

All the new ISR routers and switches report the chassis serial number in the "sh inventory" command.

BTW if you have the contract ID, you should be able to raise a TAC case

Thanks both of you. Well i dont need it only for a TAC case, but more for a SLA against a wendor. We are running IOS 12.2 so sh inv is not available.

I would here what Cisco wants from me on this one.

Totally agree with Narayan, "show inventory" is not even available for the 2600 series.

The command is available as a part of the new IOS feature.

But when you use this command on a 26xx, it will show the processor ID and not the chassis serial number.

OK, then i have to walk 200 m :-) Ok i'l give you all a 2 ones for this, fair?

Yup, good old fasion way of walking to the router and looking at the sticker with SN on it.

Also, if you have your order/delivery lists saved, then you can get SN's from there.

HI Narayan,

Thanks for Info. But, i was trying to locate the Device Model / IOS Version that Supports "show inventory" command.

But no results found. Thanks again for Info.

Best Regards,

From what I have seen show inventory is just a cleaned up version of show diag. I believe they report basically the same information. What has changed is that the chassis serial number is now being reported instead of the motherboard serial number.

Dear Amrtinsen,

I think by using the "sh diag" command you able to see the serial number including the chassis, and the WIC as well.
