The recommended mode during operation is INSTALL mode because it allows for more features and requires fewer resources when booting.

++Install Mode This is the out-of-the-box mode that your switch will be in. INSTALL mode uses a package provisioning file named packages.conf to boot the switch. If you happen to be in bundle mode upon boot, you can simply boot your switch in install mode by booting the software package provisioning file that resides in flash.

(once in install mode - execute the following command in global config: software auto-upgrade enable ) NOTE **Auto-upgrade includes an auto-copy process and an auto-extract process. ++Bundle Mode As noted previously, bundle mode consumes more memory than booting in install mode because the packages are extracted from the bundle and copied to the RAM. If you decide to convert to bundle mode, you will first need to download the.bin file from CCO if you don�t already have it in flash. Once in flash, you can simply change your boot statement to point to the (.bin) file: Switch#Config t Switch(config)# no boot system Switch(config): boot system switch all flash: cat3k_caa-universalk9.SPA.03.02.02.SE.150-1.EX2.bin Switch#write memory The provisioning file contained in a bundle is used to decide which packages to boot, mount, and run. Packages are extracted from the bundle and copied to RAM. NOTE **Auto install and smart install functionality is not supported in bundle boot mode.
