Lightweight to Autonomous (vice versa) Conversion…

mrncciew https://mrncciew.com/2012/10/20/lightweight-to-autonomous-conversion/


efore converting LWAP to Autonomous need to understand the type of OS image running on these platforms. I found following blog post is very useful to summarize the type of IOS & understanding its naming convention.

http://www.my80211.com/cisco-auton-labs/2011/11/19/understanding-cisco-access-point-ios-images.html

Following are the three type of IOS available & need to download the correct type before starting the conversion process.

  • k9w7 – autonomous IOS
  • k9w8 – full lightweight IOS (this is what is bundled in the WLC .aes image, and is factory installed on “mesh” APs)
  • rcvk9w8 – lightweight recovery image – this is factory installed on lightweight APs, unless a “mesh” image is specified; it lacks radio firmware

In our case we require k9w7 for Autonomous conversion. More specifically c1140-k9w7-tar.124-25d.JA.tar as my AP is 1142.

To convert Lightweight AP to Autonomous AP, need to have PC directly connected to AP’s ethernet port. If you are powering AP from the switch (i.e use PoE) then PC & AP needs to be in two switch ports in the same vlan. In my example PC is 10.10.10.1/24 & AP is 10.10.10.102/24.

Console into the access point & do the following configurations.

AP5475.d0f5.2ee7#sh ip int brief

Dot11Radio0                unassigned      NO  unset  up                    up

Once conversion process is over, you can verify the right image is on your access point.

For the LWAP conversion, use the recovery image ( e.g  c1140-rcvk9w8-tar.124-25d.JAL.tar). We can use the same command on the autonomous AP priviledge mode.

Following Cisco Support Community forum video demonstrate teh above process.

If you have WLC managed AP (currently registered to a WLC), then you can use WLC CLI command to convert that to Autonomous. In below example I have IW3702 AP on my WLC

<Cisco AP> Enter the name of the Cisco AP.

Once issue that command given AP should download new image from your TFTP server.
