I have a Cisco ASA5505 V11 firewall and would like to find out what the exact model is using the CLI since I only have a console cable avalible at the moment.
A show verison only gave me these informations:

Learning has never been so easy!
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)
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).

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

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
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
2 Steps total
Step 1: Get a Cisco serial number.
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.

- Thai PepperBloodHoundGang Oct 18, 2014 at 02:14pmI 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.
- Macebrianwhelton Oct 18, 2014 at 05:13pmFair one, should have thought of that, I've added it!
- JalapenoMitch9775 Oct 24, 2014 at 05:50pmNice work! I didn't realize that's how the SNs were comprised. Cool :)
- Pimientodirtdigger Feb 19, 2019 at 10:38amHi, and this serial, it's a SFP. Same rule?
FNS18431JBW
what can you tell about this one - Macebrianwhelton Feb 19, 2019 at 09:32pmNo, this only checks Cisco switches and Routers, you could try https://cway.cisco.com/sncheck/ is you have a Cisco support contract.
