Note: Booting in install mode from a USB flash drive or using Trivial File Transfer Protocol (TFTP) is not
supported.
Booting the Cisco Catalyst 3850 Switch in Bundle Mode
Booting a Cisco Catalyst 3850 Switch in bundle mode is just like booting a monolithic Cisco IOS Software image on
a Cisco Catalyst 3750-X Switch.
This command boots the switch in bundle mode:
Note: Booting the switch in bundle mode consumes more memory than booting in install mode because the
packages are extracted from the bundle and copied to the RAM.
You can boot the switch in bundle mode from the built-in flash memory, an external USB drive (usbflash0), or
TFTP. Bundle mode is used to boot a Cisco Catalyst 3850 Switch from the boot loader prompt.
Updating Cisco IOS XE Software
When the switch is in install mode, you can install any new Cisco IOS XE Software bundle by using the software
Install command.
Note: This command works only when the Cisco Catalyst 3850 Switch is booted in install mode.
Use the show switch command to check the status of the switch or switch stack. This example shows the status
of a two-switch stack, where switch 2 is active:
This example shows the command syntax and the console log from a software install in a stack of two switches:
