Cisco AP IOS命名规则

Note: Some older Cisco access points did not run IOS, such as the Aironet 340 which ran only VxWorks, and the 1000 series lightweight APs.  Access Point IOS is distributed as a tar file. These tar files can be downloaded from cisco.com SDS; lightweight IOS images (k9w8) are also bundled in the WLC software images (.aes.)  
The IOS image names include the following components:

platform-featureset-tar.version.tar

featureset- the set of software features supported by the image - one of:      
> k9w7 - autonomous (or "site survey") 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
> boot - bootloader image (not IOS) - normally installed by manufacturing and not updated in the field
> version- the IOS version
