Locate Serial Numbers via Network

We need to verify serial numbers on our Cisco routers for our remote sites. Is there a way to do this from either Telnet or Ciscoworks?

Using 'show version' works on some of our equipment, but the 3810s (12.0 IOS) are the main ones for which we can't get any info.

Any thoughts?



Re: Locate Serial Numbers via Network

RME within the CW2000 bundle have various reports like the Hrdware and the Detailed Device Report which can show the device serial# provided you first add the device in the RME Inventory and it goes to the managed state. For XL switches and Switches running CatOS, RME will automatically pull the serial# since both of these show the serial# in the 'sh ver' output. You can also do a telnet to the switch to verify the serial#.

But for routers, you first have to manually add the serial# in the router config using the command snmp-server chassis-id before RME can poll it. This tech tip would clear things up in detail:

Alternately, you can also update the device serial# manually if you're using RME by doing the Change Device Attributes and enter the serial#. After that running the Hardware or the Detailed Device Report would show these. Hope this helps.
