Converting a CAWAP AP into a Mobility Express AP
To convert an access point running CAPWAP image into a Mobility Express capable image, you have to download and install the Mobility Express image from a TFTP server. A single CLI command has been provided to download the Mobility Express image from a TFTP server and convert the AP Configuration to MOBILITY EXPRESS CAPABLE.
A TFTP server with Mobility Express image. See Procedure below.
A DHCP server to assign an IP address to the Cisco 1800 Series access point.
The Cisco 1800 series access point must not join any existing controller in the network when you are trying to load Mobility Express image. If you have an existing controller on your network to which the AP can join, conversion is not successful.
To convert an AP running CAPWAP image to Mobility Express, perform the following steps:
Download the AIR-AP1850-K9-<version>.tar or AIR-AP1830-K9-<version>.tar file from cisco.com to a machine running TFTP server. Do not untar the file.
Connect and login to the Cisco 1800 series Access Point CLI.
Enter enable to go to privileged execution mode.
Enter show version on the Access Point CLI. From the show version output, you can determine the AP Image type and AP Configuration and can then proceed with the conversion process.
Enter the command below to change the AP Configuration to MOBILITY EXPRESS CAPABLE.
Since the Access Point has an AP Image type: MOBILITY EXPRESS IMAGE; a new image does not be downloaded. After the command is issued, the Access Point reboots and comes up as AP Configuration MOBILITY EXPRESS CAPABLE .
If AP Image Type and AP Configuration is not available in show version, it means that the AP is running CAPWAP image. To do the conversion, execute the command below:
After AP reboots, Mobility Express starts in Day 0 and CiscoAirProvison SSID is broadcast.
