MAP Overview 195

Loading and A MAP’s operational image is the software that allows it to function on Activating an the network as a wireless access point. As part of the MAP boot process,

Operational Image an operational image is loaded into the MAP’s RAM and activated. The MAP stores copies of its operational image locally, in its internal flash memory. The MAP can either load the locally stored image, or it can download an operational image from the WX switch to which it has connected.

After the MAP establishes a connection to a WX switch, the MAP’s bootloader determines if the WX switch permits the MAP to load a local image or if the image should be downloaded from the WX switch.

The MAP loads its local image only if the WX switch is running MSS Version 5.0 or later, and the WX switch does not have a newer MAP image than the one stored locally on the MAP. If the WX switch is not running MSS Version 5.0 or later, or the WX switch has a newer version of the MAP image than the version in the MAP’s local storage, the MAP downloads the operational image from the WX switch.

The bootloader also compares the version of the local image to the version available from the WX switch. If the two versions do not match, the image is downloaded from the WX switch, so that the MAP’s local image matches the version from the WX switch.

After an operational image is downloaded from the WX switch, it is copied into the MAP’s flash memory. The MAP then reboots, copying the downloaded operational image from its flash memory into RAM.

Obtaining Once the MAP loads an operational image, either from local storage or Configuration downloaded from a WX switch, the MAP receives configuration

Information from the information from the WX switch to which it has connected. This WX Switch information includes commands that activate the radios on the MAP,

regulate power levels, assign SSIDs, and so on.

After the MAP receives the configuration information from the WX switch, it is then operational on the network as a wireless access point.
