Software Boot Modes - Cisco Catalyst 9500 Manual

Performing Device Setup Configuration
• Software rollback to a previously installed package set.
• Emergency installation in the event that no valid installed packages reside on the boot flash.

Software Boot Modes

Your device supports two modes to boot the software packages:
• Installed mode
• Bundle mode
Installed Boot Mode
You can boot your device in installed mode by booting the software package provisioning file that resides in
flash:
Switch: boot flash:packages.conf
Note The packages.conf file for particular release is created on following the install workflow described in the
section, Installing a Software Package.
The provisioning file contains a list of software packages to boot, mount, and run. The ISO file system in
each installed package is mounted to the root file system directly from flash.
Note The packages and provisioning file used to boot in installed mode must reside in flash. Booting in installed
mode from usbflash0: or tftp: is not supported.
Bundle Boot Mode
You can boot your device in bundle boot mode by booting the bundle (.bin) file:
switch:
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. The ISO file system in each package is mounted to the
root file system.
Unlike install boot mode, additional memory that is equivalent to the size of the bundle is used when booting
in bundle mode.
Unlike install boot mode, bundle boot mode is available from several locations:
• flash:
• usbflash0:
Note This feature is not supported on the Cisco Catalyst 9500 Series High Performance
Switches.
