Software Install Overview
The Software Install feature provides a uniform experience across different types of upgrades, such as full
image install, Software Maintenance Upgrade (SMU), In-Service Software Upgrade (ISSU)and In-Service
Model Update (data model package).
The Software Install feature facilitates moving from one version of the software to another version in install
mode. Use the
install
command in privileged EXEC mode to install or upgrade a software image. You can
also downgrade to a previous version of the software image, using the install mode.
The method that you use to upgrade Cisco IOS XE software depends on whether the switch is running in
install mode or in bundle mode. In bundle mode or consolidated boot mode, a .bin image file is used from a
local or remote location to boot the device. In the install boot mode, the bootloader uses the packages.conf
file to boot up the device.
The following software install features are supported on your switch:
• Software bundle installation on a standalone switch.
• Software rollback to a previously installed package set.
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
The packages.conf file for particular release is created on following the install workflow described in the
section,
Installing a Software Package
.
Note
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.
