Cisco devices have a standard serial number, from the serial number you can work out it's age and the location it was built. To decipher the serial number, here's how it is composed. Cisco S/N format is LLLYYWWXXXX. LLL = Location code (i.e. FOC = FoxConn China). On any Cisco network component, the show version command is applicable to any of the hardware using Cisco Internetwork Operating System (IOS), including switches. The show version command displays slightly different information depending on the type of device you use it on. Look at the output of the. Locate the serial number tag on the router chassis. The serial number is displayed in the banner during boot. “show version” command. (Look for “Processor board ID”) “show inventory” command. (Look for “Hw Serial#” or “SN:”) “show diag” command. (Look for “Chassis Serial Number”) “show hardware” command. Just to be extra confusing, the Cisco Small Business line of switches (SG300, SF300, etc) use a different command to display the serial number: show systemid. There is a show version command, but it does not include the serial number for whatever reason.

The simple steps below will show you the easy way to locate Cisco catalyst switch serial numbers.Cisco Catalyst 6500/6000 Serial Numbers:Cisco Catalyst 6500/6000 switches can run CatOS system software on the Supervisor Engine and Cisco IOS Software on the MSFC. Or, the switches can run Cisco IOS System Software, with a software bundle for both the Supervisor Engine and MSFC. Cisco CatOS System SoftwareUse the show version command to determine the serial number of various hardware components, as this example below shows:Note: If the power supply serial number is not visible in the show version command output, issue the show sprom powersupply {1 | 2} command. In order to find the serial number of port adapters that plug into the Flex WAN module, issue the show diagbus command from the MSFC command-line interface (CLI).
Cisco Catalyst 5500/5000 Serial Numbers:Use the show version command to determine the serial number of various hardware components, as this example below shows: Note: Use the show diag command on the Cisco Route Switch Module RSM with Cisco Versatile Interface Processor VIP WS-X5304= to find the serial number of port adapters.
