Not sure if it is possible.

On a 1231AG-A-K9 for example, the show hardware does not give a date for manufacture, but it does return the following:

Part Number : 73-8704-07

PCA Assembly Number : 800-23211-08

PCA Revision Number : A0

PCB Serial Number : FOC084103AQ

Top Assembly Part Number : 800-23304-07

Top Assembly Serial Number : FTX0843J239

Top Revision Number : B0

Product/Model Number : AIR-AP1231G-A-K9

Hi Thomas,

Not sure about finding the Manufacture date (maybe you are trying to find out about the presence of a MIC certificate) but we did go through this coversion from Autonomous to Lightweight on our infrastructure last summer.In this process we did convert about 70 1121's and 1231's to LWAPP and it worked very well. Here are some relevant docs;

Upgrading Autonomous Cisco Aironet Access Points to Lightweight Mode

From this excellent doc;

The following Cisco Aironet access points have the ability to operate as autonomous access points or lightweight access points:

Cisco Aironet 1240 AG Series Access Points

Cisco Aironet 1230 AG Series Access Points

Cisco Aironet 1200 Series Access Points that contain 802.11g (AIR-MP21G-x-K9) and/or second-generation 802.11a radios (AIR-RM21A-x-K9 or AIR-RM22A-x-K9)

Cisco Aironet 1130 AG Series Access Points

Cisco Aironet 1100 Series Access Points that contain 802.11g radios (AIR-AP1121G-x-K9)

Cisco Aironet 1300 Series Access Points/Bridges (AIR-BR1310G-x-K9 or AIR-BR1310G-x-K9-R).

Self-Signed Certificate Manual Addition to the Controller for LWAPP-Converted APs

LWAPP secures the control communication between the AP and the WLC by means of a secure key distribution. The secure key distribution requires already provisioned X.509 digital certificates on both the LAP and the WLC. Factory-installed certificates are referenced with the term "MIC", which is an acronym for Manufacturing Installed Certificate. Aironet APs that shipped before July 18, 2005, do not have MICs. So these APs create an SSC when they are converted to operate in lightweight mode. Controllers are programmed to accept SSCs for the authentication of specific APs.

LWAPP Upgrade Tool Troubleshoot Tips

Also, 5 points for Eric! For all your great work here lately.

Hope this helps!


The command (requires enable level) you want to determine if the AP has Manufacture Installed Certificates is: "test pb display"

Example below AP *HAS* MIC

ap1# test pb display


Display of the Parameter Block


Total Number of Records : 7

Number of Certs : 6

Number of Keys : 1


From an older AP without a MIC you get:

ap2# test pb display

Parameter Block Doesnt have any Records


Separately, has anyone come up with a way to put the necessary SSCs into an older AP *without* using that PC based upgrade tool? We want a way where we can define SSCs and capture the SHA1 Hashes well in advance of us upgrading the AP firmware and switching away from autonomous mode.
