Cisco devices have a standard serial number, from the serial number you can work out it's age and the location it was built.

Is there any tool that can autodiscover all Cisco Routers,Switches devices on the network with all the Serial number, Cisco IOS info without running individual. However, this would require that the candidate provide you with his or her 16-digit certificate verification number. Cisco Learning Network Moderator. Like Liked Unlike Reply. Edited by Admin February 16, 2020 at 3:53 AM. Hi, Can you help for my certificate. I had my certification on 20/1/2017 but till. 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. In later releases of the Cisco MDS 9509 Director, the chassis serial number label was moved, as shown in Figure E-2. Earlier releases may have the serial number label on the right side instead of the left. Figure E-2 Serial Number Location on Cisco MDS 9509 Director The Cisco MDS 9506 Director chassis serial number label is shown in Figure E-3.

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)
YY = Year code (08 = 2004...09=2005...etc...)
WW = Week code (weeks 01 to 52)
XXXX = Base-34 Alpha Numeric Unique identifier (Includes 0 to 9 & entire alphabet except I & O).

Location codes:
CTH --- Celestica - Thailand
FOC --- Foxconn - Shenzhen, China
JAB --- Jabil - Florida
JPE --- Jabil - Malaysia
JSH --- Jabil - Shanghai , China
TAU --- Solectron - Texas
PEN --- Solectron - Malaysia

Year codes:
01 = 1997
02 = 1998
03 = 1999
04 = 2000
05 = 2001
06 = 2002
07 = 2003
08 = 2004
09 = 2005
10 = 2006
11 = 2007
12 = 2008
13 = 2009
14 = 2010
15 = 2011
16 = 2012
17 = 2013
18 = 2014

Step 1: Get a Cisco serial number.

Cisco Serial Number Search

We'll use FOC0849N1BD.
The serial number can be obtained by looking at the rear of the device and it will be a white sticker with black printed letter, alternatively enter the command 'show version' onto the command line and look for the serial number in the output.

Step 2: Deciper!

FOC0849N1BD
Built in Foxconn, China in 2004 in week 49 of production and it's unique code is N1BD.

Knowing the actual age, not the purchase age, of you Cisco equipment can aid in forward planning for techical refreshing of you equipment.

  I think if you explained hot to pull the serial number from the device along with this it would have been more informative. But good information thanks for sharing.
