Update IOS XE
Install mode is the recommended mode for booting a switch. This is due to the fact that bundle mode requires more memory, is slower to boot, and auto-upgrade for example isn’t supported in bundle mode.
Bundle mode is the legacy way of booting a switch using a .bin file which is referenced directly in the boot system command.
Install mode on the other hand expands (extracts) the bin file to flash ahead of booting. These .pkg files are then referenced in the packages.conf file which is the file we point to with the boot system command.
